Dear Python.org Support Team,

I have already tried the following:

However, despite my efforts, I have been unable to successfully uninstall
the corrupted Python installation.


The more stuff you remove by hand the harder it is for the Windows 
installer to act to do an uninstall.


This tool usually helps if things are badly messed up:

Haven't used it for a while, but after it tries basic overall repairs to 
the installation subsystem (which is probably okay), there are prompts 
you can follow to point to a specific program that doesn't want to 
uninstall.

Windows restore any of the OS files if they have been damaged.  If 
everything is OK, then that would remove one potential issue, so it's

Here's what to do. First, open a console with administrative privileges

If repairable problems are found, then run:

dism /Online /Cleanup-Image /RestoreHealth

Finally follow up by running

sfc /scannow

sfc can also repair some errors, and some people run it first, but I 
have read that it's more useful to run Dism first.


If any errors were found and corrected, reboot and try to uninstall 
Python3.11, then re-install it.


If no errors were found, report that back here and we'll try to go on 
from there.


If it were me, the next thing I'd try is to install Python 3.10.x.  I'd 
get a 64-bit installer from python.org. Yes, I know you want to install 
3.11, but this way will give you a clean, fresh installer to try.  If 
the installation succeeds, it would be a good data point and also give 
you a (somewhat) updated version of Python on your system.


I would like to ask you for help. I have been using Python 3.8 for 
almost 2 years and I decided to update to 3.11. Initially everything 
was correct. But at some point Windows shows me that Python is being 
reinstalled (I don't have a message print screen ..), but from that 
time I cannot run Python at all on my PC.


So I tried to reinstall it several times with no success. All the time 
I receive this "The system cannot find the file 
C:\Users...\AppData\Local\Programs\Python\Python311\python.exe."

But files are there:
[cid:image001.png@01D953B0.4E12E170]

Strange thing is that after RE-Installing Python the "pip.exe" is 
missing in subfolder "Python/Scripts/" (it is simply empty - not 
installed but I mark pip to be installed):

That indicates two things: One, you are logged in as "Lenovo" and Two,
you are not running the installer with Admin privileges (or installed using
the "current user" option).

Install using admin privileges and select the "All Users" option.
Though I'd recommend installing to a simple C:\Python310. If you install in
the system default "Program Files" directory any updates (which may be PIP
module installs) will need to be done under admin privileges.

Someone chose that name. If M$ were choosing user names based on
manufacturer there would be thousands of "Lenovo" user names out there, and
that would not be possible for a "M$ login" (it would be possible for
"local machine" logins).

Furthermore, one CAN set up Windows 10 WITHOUT creating a Microsoft
Domain Login. Local login accounts can be created. The only reason I have a
M$ login on my machine is that they may want it for their "app store" and
things like Visual Studio -- my machine, however, is not logged in using
the M$ account, just my local username.

The second page of Advanced Options has a section to customize the
install location.

If some vestige of the old installation lives on, so the installer
thinks it's modifying an existing install rather than a fresh one, that
option would be greyed out.

You are (re-)running the INSTALLER. Once you've run it, hide it away
someplace and only look at it if you need to -- well -- repair or modify
the installation.

Python is not an IDE (it is not something like Visual Studio where one
opens a massive suite of editing/debugging tools which will eventually
invoke Visual C/C++/C#/BASIC compilers). It is a command line interpreter
which might (depending on install setting) configure the system to use it
to run files with .py (or .pyw for GUI applications where a console window
is not desired... note that running a .py by clicking on it will open a
console window, and that window will close when the program exits -- so
that option is often useless).

Is it possible that Python is already installed?

Open "Command Prompt" window, type python and press "Enter".

Hello,

I hope this email finds you well.

I have been trying to download and install the latest version of python on
my windows device. However, when I run the program, three options arise.
These are:

Modify
Repair
Uninstall

I have executed the modify and repair options several times but nothing has
changed. Please advise on what the problem could be and how it can be
resolved.

I look forward to hearing from you.

Thank you,

Thank you!



you asked this before, and didn't answer the questions you got in reply.

What does "doesn't work" mean? How is the problem manifested?  Doesn't 
IDLE selected from the start menu come up? Normally the installation 
creates a shortcut there that "does the right thing".  On Windows you 
don't normally start IDLE by typing a command name. You *can* bring it 
up from a command-line if you type


py -m idlelib

but this is definitely not the most common way to launch.

If you haven't read it, look at

https://docs.python.org/3/using/windows.html


among other things, the Microsoft Store version of Python is sometimes a 
little easier to get started with (it's the same programs, just packaged

You do not provide much detail to diagnose what your problem(s)
is(are).  By the "earlier one" is it the same version as the one you
re-installed?  Were you able to run IDLE with the "earlier one"?  By
not being able to import modules do you mean modules from Python's
standard library?  Or do you mean installing third party libraries
using pip?

> ...But now I am not able to open IDLE after multiple tries.

Have you looked in your start menu in the list of installed programs
for Python?  If it is there did you expand it and see if there is an
entry for IDLE?  How have you been trying (unsuccessfully) to open
IDLE?

Issue with Python installation for a beginner Python coder.

[Sarvesh Poddar via Python-list]

Hi,
I re-installed Python in my Windows system as the earlier one was not able to 
import modules. But now I am not able to open IDLE after multiple tries. 
Can you guys help me? I am a beginner and tried out a lot of solutions provided 
on the internet and it's just not getting fixed.
Please help. I look forward to it. 
PS : Falling in love with Python, slow and steady!

My experience of teaching total novice programmers is that you really
can't shirk the fundamental question: how should I install this thing

For grins (as boB would say) I scanned Oracle's intro pages to Java 
programming (JDK), and they have a logical progression from installation 
instructions to "proving" the installation with the ubiquitous 
Hello-World first-program.


Whereas the MySQL web site requires one to select the appropriate 
download and then remember (!) to keep reading. Whereupon the manual 
offers advice about testing the server, etc.


Whereas those are decades old and well-established, in case of 
comparison the 'younger' MongoDB's documentation was more complicated. 
The installation of the server was not followed by a link to information 
about running the client, to be able to assure the system and understand 
the most basic (debugging?) linkage.



None of these are suited to the 'smart phone' world, where software is 
selected from an 'app store' and once installed, 'it just works'. Is 
that where these neophyte users' troubles start - a disconnect between 
such expectations and the Python reality?
(it's all very alien to my Linux world/memories of MS-Win .msi files 
with a check-box at the end which invited a start-up or display of 
suitable help files)


Yes, the observation that we have folk who are quite probably 
downloading a command-line program(me) for the first time in their 
lives, but is that a valid excuse?



What I've run out of time to compare-and-contrast is the advantage of 
pointing users at a Python-environment distribution, eg Anaconda. If 
'we' are less interested in caring for beginners and their basic needs, 
should we point them at others who are?



Observations (further to/underlining @Oscar's points):

- the requirements of a beginner installing for the first time (and 
maybe his/her first programming language) are totally different to 
someone wanting to install a new version of Python or on a new machine. 
(ie done-it-all-before/want it to be quick-and-easy/don't bother me with 
loads of docs)


- most docs seem to try to be 'all things to all people', whereas the 
differences between platforms inevitably make the writing complicated 
and the reading difficult to follow. Thus, consider separating entries 
by OpSys and/or installation method.


- a reference manual is not 'the place' for beginners, who require a 
more tutorial/hand-holding approach


- a beginners' installation tutorial should include a first program(me) 
and thus run through the command-line/editor/execute/REPL etc 
philosophies. This may be opening yet another

I would say that the official tutorial is not targeted at the total
novice. I think it used to be described as the tutorial for people
with experience of programming in other languages but I might be
misremembering.

The main python.org page links to a "beginners guide" well actually
there are two beginners guides...
https://www.python.org/

Under "get started" there is a link to this beginners guide:
https://www.python.org/about/gettingstarted/

You can also hover over documentation and choose beginners guide to
get this one:
https://wiki.python.org/moin/BeginnersGuide

The former starts by asking whether you are new to programming and if
so suggests this page:
https://wiki.python.org/moin/BeginnersGuide/NonProgrammers

It also has an "installing" section which links to here:
https://wiki.python.org/moin/BeginnersGuide/Download

All of these have lots of information and many links to other pages.
I'm not sure how you'd find the page dn linked to which is at least
more direct about how to install:
https://docs.python.org/dev/using/windows.html

Certainly I don't see it if I go straight to the download pages:
https://www.python.org/downloads/
https://www.python.org/downloads/windows/

I think if I was new to programming or installing software in general
I would find all of this quite bewildering.

My experience of teaching total novice programmers is that you really
can't shirk the fundamental question: how should I install this thing
and start using it *before* I have any idea what I'm doing? Novices
don't need to be told that there are 100 ways to do it: they need to
be told exactly how to do it in a way that will work for them.

If I was writing the tutorial but aiming at total novices I would
probably begin by suggesting to use an online shell:
https://www.python.org/shell/

There could be a short guide there that explains very clearly how to
do simple commands in that online shell. At that point you are ready
to test the examples from page 3 of the official tutorial but I think
it is still not pitched at novices:
https://docs.python.org/3/tutorial/introduction.html

Then after a few examples and some familiarity it could be time to
suggest installing locally. That should be with a no nonsense
explanation that makes no reference to terminals, PATH, etc because
those are just intimidating distractions to a novice at that point in
time.

The sympy docs have a lot of room for improvement but one of the
things that is very useful for beginners there is the "Run code block
in sympy live" button which means that you can follow the
tutorial/docs and try things out before having anything installed
locally:
https://docs.sympy.org/latest/tutorial/intro.html#introduction

Fwd: Removing python installation

[Shawn Hoffman]

I've somehow wound up in a situation where I have both 3.7.5 and 3.7.6
installed, and the py.exe launcher can find both of them, and defaults
to the older one:

>py -0p
Installed Pythons found by py Launcher for Windows
 -3.7-64"C:\Program Files (x86)\Microsoft Visual
Studio\Shared\Python37_64\python.exe" *
 -3.7-64C:\Users\shawn\AppData\Local\Programs\Python\Python37\python.exe

As you can see, the 3.7.5 install is from Visual Studio. I want to
remove this python installation, however while uninstalling it via the
VS Installer GUI appears to work, none of the files are removed. Only
the json file VS Installer uses to track the package is removed. In
the VS Installer logs, I see:

Skipping uninstall of 'CPython3.Exe.x64,version=3.7.5,chip=x64'
because it is permanent.

which seems suspicious.

Additionally, in the aforementioned json file I can see the installer
being used is "python-3.7.5-amd64.exe" from
https://go.microsoft.com/fwlink/?linkid=2109129 , with args:
"/quiet /log \"[LogFile]\" InstallAllUsers=1 CompileAll=1
Include_symbols=1 TargetDir=\"[SharedInstallDir]\\Python37_64\""

So, I've downloaded this installer and tried to run it with the
/uninstall option. Again, the uninstall appears to complete OK, but
the files are not removed.
The uninstall log is here:
https://gist.github.com/shuffle2/3c3aa736f5cf9579e6e4a4a33b1ad81d

Is there some "clean" way to remove this VS-installed 3.7.5 (and not
break the 3.7.6 install)?

Thanks,
-Shawn

What is this "Unscramble software?"

After Python is installed, you probably will find the "Idle" integrated
development environment in your start menu under "Python."

Looks like recent versions of Python default to installing into your
home directory under AppData\Local\Programs\Python-38-32 (or -64).  Look
in there for python.exe and pythonw.exe.  Please note that Python is not
like Visual Studio. It's an interpreter that is meant to be run from the
command line with python script files you create in an editor.

It may also be helpful to click the option in the installed to add
Python to the PATH. That way you can just run python.exe from any
command prompt.

I prefer to keep communication on the list.  Where did you download the
installer from?  Python.org or some other distribution like Anaconda?
Are you installing for all users, or just for your current user?  What
has google found about this error message and python?  Does google tell
you whether anyone else has seen this error message while installing
Python before?

I don't have Windows, so I can only speculate, and do the same google
searches you can do.

Finally, have you tried installing Python through the Microsoft Store on
Windows 10?  It's officially released by python.org core devs and should
always be free.

Segmentation violation with python installation under Tumbleweed

[amitsis]

Hello,

My full Python installation doesn't seem to work due to a segmentation 
violation issue with libc-2.30:

Dec 30 23:54:14 craylinux1 Kernel: Python [8467]: Segfault at 100013483 ip

I think this is just a bug of mismatched binaries and libraries in my Python 
installation.

I want to reinstall the full Python installation including the libraries now, 
but how can you do it with Zypper to get a clean Python environment again?

Any help with the detailed command lines would be greatly appreciated.

RE: Python installation - fatal error

[Nagendra Babu Thillaiappan]

 

Hi, 

I am a new user to Python and was trying to install version 3.6.5 (on a
Windows 7 64-bit machine). However, I installed a different version by
mistake and had to uninstall it. 

Then I tried installing version 3.6.5 using the .exe file, and it
returns a fatal error (log in attachment). 

Can I request your help in sorting this out? 

Thank you.

The problem with locale went away when I changed DEFAULT_LANG from en to
sv in conf.py. 

pip list still throws exceptions at me but I have a plan. My secondary
computer has a very similar Debian installation. There are no Python
issues on that machine so I will do some comparative research.

Yes, it does, you should avoid that at all cost. The best way to do it
is by using virtualenv.

That’s a warning, and it happens to be caused by the `rpl` apt
package. Remove it from your system and try `pip --version` again:
https://github.com/certbot/certbot/issues/3795

Now, onto fixing Nikola issues:

As discussed on IRC, Nikola recommends (and will soon require) Python
3. And you’ll be better off with a virtualenv: install `virtualenv`
from apt and follow the Getting started guide for Nikola:
https://getnikola.com/getting-started.html

If you still get unicode issues when compiling posts, make sure
they’re saved as UTF-8, and that your locale is configured properly:

No web server is involved in this. Programs like Nikola takes pictures,
text files (Markdown, ReStructuredText...) + templates as input and
spits out html, css and sometimes javascript. Then it is up to you to
copy that result to a web server.

Exceptions. (Disclaimer: I am not a Python expert).

Today I tried pip --version and got the following:
/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py:1892:
UserWarning: /usr/lib/pymodules/python2.7/rpl-1.5.5.egg-info could not
be properly decoded in UTF-8
  warnings.warn(msg)

Reinstalling Python and pip makes no difference. pip3 --version throws
no warnings.

If this site is accessible from the internet, have you looked around other 
parts of the system? Like date/timestamps for /bin/*. I recently was asked to 
look at a friends web site and found they were doing several things that I 
consider a security no-no, like running the tomcat server as root to serve 
their web site. It had been root-kitted. I helped them setup a new system 
that ran tomcat under a non-priv user.

It's just a SWAG, but perhaps something further is amiss that you don't see. 
I was really surprised that my friend, a pretty good programmer, was clueless 
about such things.

The only other time I've seen python "damaged" was when some developer 
decided they wanted a more current version than the default installed on the 
CentOS system (2.6) which is required for updating the system. They borked it 
beyond repair and my boss took away root access after we repaired it.

Exceptions or crashes of the python interpreter ?

Repairing Python installation?

[Martin Schöön]

It seems something is amiss with my Python 2.7 installation. Revisiting
Nikola (static web site generator written in Python) for the first time
in several years the other day I experience some unexpected problems. I
got some help form the Nikola people and the conclusion is something
is broken with my Python 2.7. Pip list throws exceptions at me while
pip3 list works the way I expect it to do.

All this is happening on a Debian machine.

Questions:

Should I try to pinpoint what is broken (and how is that done) or should
I just remove everything Python 2.7 and re-install?

Could mixing pip installs with Debian distro installs of Python
packages lead to conflicts or other problems?

TIA,

/Martin

I've tried PyInstaller (development version) and it works with Python 3.6:

  $ py -3.6 -m pip install

Sure you can. You just have to do it like this (untested; I haven't used
Windows in many years):

@echo off

start %~dp0dist\python-3.6.0-embed-win32\python.exe %~dp0dist\app.py %*

I think %* expands to all the commandline parameters, apparently
excluding %0, which would be the command name itself.

How to run self-contained Python scripts who don't need Python installation?

[Juan C.]

I need to run some Python 3.6.0 scripts on the users' machines (W7 and
W10) in an enterprise environment, but I can't install Python on those
machines. I tried looking for those "py to exe", but sadly they don't
support Python 3.6.0. Then I found out about "Windows x86/x86-64
embeddable zip file" that Python.org made available since 3.5.0, and I
thought it would be the right thing for my case.

I have some questions regarding embeddable Python:

1. How can I install custom modules using pip?

2. I'd like to create a simple BAT to run my Python script, so there
would be only 2 things (a 'dist' folder with everything and a run.bat
to make it clear what should be run), for example:
@echo off
start %~dp0dist\python-3.6.0-embed-win32\python.exe %~dp0dist\app.py

The issue is that I can't parse args to app.py in this case. How would
that be possible? In the example above, if Python was fully installed,
I would give a file as argument to app.py, generally clicking and
dragging the file into the app.py icon so that it would start.

3. Is there a better approach for my case other than embedded Python?

The CRT update also requires service pack 1 on Windows 7 and service
pack 2 on Vista. 3.5.1's installer was updated to check for a
supported operating system. On an XP system the error message should
be "Windows Vista SP2 or later is required to continue installation".

I think there are several different issues to do with Python 3.5 and Windows.

Firstly support for Windows XP was dropped and 3.5 was made in a way
that is incompatible with XP. However initially neither the download
page nor the installer were warning XP users leading to a lot of
confusion. I thought this was suppose to have been fixed in 3.5.1
though so the installer should now warn that it won't work on XP.

Secondly the Windows builds of 3.5 are now compiled using VS2015 and I
believe the installer itself has had something of an overhaul. This
seems to have caused a number of different problems. One problem is
that the newer VS2015 runtime requires the installation of some dll
from Microsoft. So some users are getting error messages about a
missing dll.

The error message quoted above is something else though. I can't tell
but it seems as if there are a number of distinct issues caused by the
significant changes to Python 3.5 on Windows.

> Should this be raised on python-dev?

Probably better to go for bugs.python.org. There's a few 3.5/Windows
issues already there. Not sure if this one's already listed.

I am not a Windows user, but this question occurs a lot.

Is this cryptic message a missing dependency of the installer or of Python.  
Because if it is Python surely we should be doing potential users a favour and 
mentioning this 3.5 vs XP (and earlier?) issue in nice human friendly prose

As things stand, many users infer that they have a corrupt or broken download, 
not that they needed a different version of Python.


Should this be raised on python-dev?

Python Installation

[Kin Zhao]

Hello,

I had a similar problem as Jim Conyngham (DieInSente) as shown in the link
below.

Uninstalling from the uninstall exe doesn't actually, fully uninstall the
program. It just removes it from the menu and the folder in All Program.
You'll have to uninstall with the initial installation exe. That's what I
did and it removed the wrong version for me so I can install the 64 bit
version of Python 3.4 on my computer. Can be a bit annoying, if you have to
figure out which exe you used after trying so many.

The error message comes up, because it's already downloaded. Even though it
says it's overwriting the older one, it doesn't actually overwrite it and
that's where the problem is.

Link: https://bugs.python.org/issue22028


Thanks,

Kin Zhao

I'm totally confused.  You started out asking about problems getting

mod_wsgi to load you are asking a Python group about a PHP module.  Slow

That's a much MUCH harder thing to do than running Python code in your
web server, because of trust issues. I don't know how it's set up, but
there'll be something in there to protect the server against malicious
or accidental insanity (spinning with "while True: pass", trying to
read/write files, trying to execute commands, using up all of RAM with
"x = []\nwhile True: x.append(1)", etc, etc, etc). That's actually a

The ".\configure" thing is for Linux installations using autotools; it's

I don't run Apache on Windows, so I'm just guessing from the documentation  
here, but the mod_wsgi "Installation on Windows" page says to "follow the  
instructions for loading mod_wsgi in the Quick Installation Guide."  The  
"Quick Installation Guide" page has instructions for editing the Apache  
config files.  No mention of running ".\configure" -- why are you doing  
that?  Try just editing the config files as the documentation suggests and  
see if that works.

python installation on windows

[rborole06]

Hi Everybody

actually i want to run python on web browser. I downloaded python and installed 
but i'm not able to run it in browser but it running using command prompt. so i 
trying to install mod_wsgi 3.4. So i downloaded precompiled version 
mod_wsgi-3.4.ap22.win32-py2.6 and copied mod_wsgi.so file to 
C:\wamp\bin\apache\Apache2.2.11\modules after i'm trying to run .\configure on 
path C:\Documents and Settings\Rahul\Desktop\mod_wsgi-3.4.ap22.win32-py2.6 but 
it giving me error that .\configure is not recognized as internal or external 
command.

So please suggest me what can i do for that, i'm so beginner to python and 
installing and configuring modules for apache.

Thanks

Python installation/cleanup management

[Asaf Las]

Hi

What is the best way to manage Python isolated from 
/bin /usr/bin ... installations done via source code 
compilation on yum/rpm based systems? 

there are some alternatives i guess could be done: 

* configure --prefix, then delete
* checkinstall
* fpm (questionable for python?)
* make altinstall and diff fs for pre post changes 
* diving into rpm spec file
---
* any other?

main objective is to figure out upgrade or python 
release test methods done in least painless way. 

have searched issue but either missed or there is no 
much comparison of above.  

Thanks

The solution is of course to replace all duplicates by hard links.
A tool for this is useful in a lot of other circumstances too.
In a re-installation of the whole or parts, the hard links
will be removed, and the actual files are only removed if they aren't needed
for any of the installations, so this is transparent for reinstallation.
After a lot of reinstallation you want to run the tool again.

This is of course only possible on real file systems (probably not on FAT),
but your files reside on a server, so chances are they are on a real file
system.

(The above is partly in jest. It is a real solution to storage problems,
but storage problems are unheard of in these days of Tera byte disks.
It doesn't help with the clutter, which was probably the main motivation.)

Symbolic links are not as transparent, but they may work very well too.
Have the common part set apart and replace everything else by symbolic links.

There is always one more way to skin a cat.

Gak.  Never mind.  That's what you get when you're trying to hack
relocatable installations at 3am: even after some sleep you think you
know what's going on.

PYTHONHOME accepts a colon-separated list for prefix:exec-prefix.  This
is even clearly documented, even in the error output from the
interpreter when it can't find its installation!

Making this change in my wrapper script for GDB gets everything working.

Cheers!

I don't have any experience with your actual issue, so though I've
been reading your posts, I haven't anything to add to the thread. But
one small side point: If you're going to propose patches that
materially change functionality, they won't be applied to 2.7, which
is now closed for new features (and there won't be a 2.8). So the
first thing I'd recommend doing is trying the same things with 3.3, or
possibly an alpha of 3.4 (or the beta, if you can wait one week for
its launch). If it's exactly the same, then you could propose changes
to the 3.x branch (probably too late for 3.4 now, but 3.5), and
possibly they could be backported to 2.7 if it's considered a bugfix.
Or you might find that, by the magic of Guido's time machine, the
problem's already been solved in 3.x!

Maybe you can't actually migrate your codebase fully, but at very
least, try this sort of thing in both versions - at worst, you spend a
bit of time spinning up a duplicate and then say "Same thing happens
in 3.3.2".

Ouch.  I spoke a bit too soon.

The standard Python installation and interpreter works fine with the
"split --prefix and --exec-prefix" configuration, even with relocation
of the installation directory.  However, that configuration doesn't work
for embedded Python (for example, if you embed the Python interpreter in
GDB by linking libpython2.7.a) if you relocate it.

In that configuration when the interpreter looks for the lib/python
directory at runtime it appears to use only the prefix path Python was
originally compiled with (I'm using strace on Linux to see what paths
are being probed at startup).  It doesn't use the "current installation
path" via argv[0], which means it's not relocatable at all.

I can, of course, set PYTHONHOME to point to the right place.

Unfortunately, if you set PYTHONHOME then it's used for both $PREFIX and
$EXECPREFIX without any path probing whatsoever, so PYTHONHOME is
unusable with an installation where you've used different values for
--prefix and --exec-prefix during configure.

We'd need a new environment variable, like PYTHONEXECHOME or something,
which would be tested first when looking for the exec_path (only).  If
that didn't exist, it could try PYTHONHOME as before.

I'm willing to do this and file a bug with a patch if there's any
interest in pursuing it further.  Or should this be discussed on
python-dev?

OK, after some investigation and reading the code in Modules/getpath.c
to determine exactly how sys.prefix and sys.exec_prefix are computed (it
would be nice if this algorithm was documented somewhere... maybe it is
but I couldn't find it) I have a solution for this that appears to be
working fairly well.

In order to get this to work you need to use the following arguments
when you run "configure" to build your Python:

configure --prefix=$PREFIX --exec-prefix=$PREFIX/$ARCH

where $ARCH can be pretty much whatever you want, but should be unique
for each different architecture of course.  The $PREFIX should be the
same for all architectures.

The magic here is ensuring that the --exec-prefix directory is a
SUBDIRECTORY of --prefix.  If that's not true, nothing works!

The resulting python interpreter will live in $PREFIX/$ARCH/bin: you
have to leave it there!  If you move it nothing works.  Although you can
get rid of the "bin" and move it up into $PREFIX/$ARCH if you want;
that's OK.

What I do is have a little shell-script wrapper installed somewhere else
that runs 'exec $EXECPREFIX/bin/python "$@"'

You can also correctly install extra packages with setup.py, even if
those packages have their own shared objects (like pycrypto or
whatever).

I should say, I've not thought about Windows yet.  I don't know if this
will work out for Windows.  However, Windows is such a different beast
anyway I think (at least in my environment) it will be OK to treat it
separately and require Windows people to download/install their own
Python.


There are few nitty things that I needed to handle:

 1. The _sysconfigdata.py file is put into $PREFIX not $EXECPREFIX,
which is wrong since that file is very much
architecture-specific.  As a post-processing step I moved it
from $PREFIX/... into $EXECPREFIX/.../lib-dynload.  It's not
quite correct since it's not a dynamic object, but lib-dynload
is the only standard path on sys.paths from $EXECPREFIX.  It
works OK anyway.
 2. All the scripts, even the ones in $PREFIX/bin, have hardcoded #!
paths which go to a specific python in $EXECPREFIX/bin which is
wrong (they can't be shared that way).  I use a simple "sed -i"
to replace them all with "#!/usr/bin/env python" instead.
 3. There are some scripts that get dumped into $EXECPREFIX/bin
rather than into $PREFIX/bin: "2to3", "idle", "pydoc",
"smtpd.py".  I think this is simply a bug in the installation
and those should all go into $PREFIX/bin.

Another weird thing is that the normal installation (this has nothing to
do with the above; it happens even if you don't set --exec-prefix)
contains TWO copies of libpython2.7.a; one in $EXECPREFIX/lib and one in
$EXECPREFIX/lib/python2.7/config.  These are over 14M each so it's not
inconsequential to have two.

I'm deleting the one in lib/python2.7/config and things still seem to
work OK.  The pkgconfig python definition references the one in
$EXECPREFIX/lib.

Sharing Python installation between architectures

[Paul Smith]

One thing I always liked about Perl was the way you can create a single
installation directory which can be shared between archictures.  Say
what you will about the language: the Porters have an enormous amount of
experience and expertise producing portable and flexible interpreter
installations.

By this I mean, basically, multiple architectures (Linux, Solaris,
MacOSX, even Windows) sharing the same $prefix/lib/python2.7 directory.
The large majority of the contents there are completely portable across
architectures (aren't they?) so why should I have to duplicate many
megabytes worth of files?

The only parts of the install which are not shareable (as far as I can
tell) are the .so dynamic objects (and the python executable itself
obviously).

If the default sys.path included platform-specific directories as well
as the generic lib-dynload, it would be possible.


I do see that there are "plat-*" directories available in the default
path.  Is it possible to make use of these (say, by renaming each
architecture's lib-dynload to the appropriate plat-* name)?


If that works, the remaining issue is the site-packages directory.
There is no ability (that I can see) to separate out the shareable vs.
non-sharable aspects of the add-on site-packages.


Any comments or suggestions?  Am I overestimating the amount of sharing
that's possible?  Thanks!

I'm the one who was talking about the build/copy. You could manually
copy a bunch of .so, but there's a reasonable chance you wouldn't need
to - in many Linux systems, you have the binary packages for heaps of
things that you don't have the dev libraries (headers, .a files,
whatever) for. At work, we have just one computer on which we build
from C source (which happens to be my personal dev unit as well); all
the other computers - other devs' laptops, staging servers, production
servers - just get binaries deployed directly. There aren't very many
libraries to install on them, as they're fully-functional Linux boxes
already (we use Debian).

It may, of course, be different on your setup, but I figured it was worth a try.

One thing I don't understand is that I thought that Python would statically
link against sqlite and tcl/tk (I presume that this is the reason why you

load libtk.so (a dynamic shared library).

Does Python then load dynamic libraries from sqlite, tcl, tk when using the
respective modules?

Re: Preparing sqlite, dl and tkinter for Python installation (no admin rights)

All

I finally solved the problem. The problem was that setup.py tests loading
the dynamic library libtk (this I don't understand, since I though Python
would statically link against TCL, TK and SQLITE.

Either way, I have updated the thread at StackOverflow with the answer:
http://stackoverflow.com/questions/16026348/preparing-tkinter-and-sqlite3-for-python-installation-no-admin-rights/16090051#16090051

but basically the answer was:

Add the following include paths through `CPPFLAGS`

* /path_to/sqlite3/include
* /path_to/tcl/include
* /path_to/tk/include

the following lib paths through `LDFLAGS`

* /path_to/sqlite3/lib
* /path_to/tcl/lib
* /path_to/tk/lib

and the following lib paths through `LD_LIBRARY_PATH`:

* /path_to/sqlite/lib
* /path_to/tcl/lib
* /path_to/tk/lib

*** WARNING: renaming "_tkinter" since importing it failed: libtk8.6.so:

...
==

The odd thing is that I can see `libtk8.6.so` under /opt/tcl8.6.0/lib,  as
I specified with `LDFLAGS`:

==
cd /opt/tcl8.6.0/lib
ls
.
../
pkgconfig
tk8.6
libtkstub8.6.a
tkConfig.sh
libtk8.6.so
==

The file libtk8.6.so  has 1.5M and is definitely there.

So why did that compilation fail?

Most supercomputers I'm familiar with have some variant of Linux running
(e.g., SUSE or Red Hat are quite common).  Some of these machines only have
barebone kernels on the compute nodes, though, and have a fully-fledged
Linux OS only on the login nodes... This info is typically on the website
for that supercomputer (if it has one), or any other available
documentation.

That said, there are other options available that are probably less of a
hassle for you:

1) Skip tkinter unless you _know_ you really need it.  Do you plan on doing
X-forwarding when you log in?  Can you run the GUI app on your local
machine before uploading the files you need for computation?  Running GUIs
locally rather than over the network is typically much faster, anyway.

2) Submit a ticket to the supercomputer staff requesting that they install
the software you need.  There may be other 'gotchas' associated with
installing certain software on supercomputers that the staff would know
best.

Good luck,
Jason
