Re: [Matplotlib-users] matplotlib, ipython and ubuntu

2008-01-29 Thread postmaster
I just migrated from edgy to gutsy this weekend. I did a clean install (boy it 
really
went smoothly - either I'm getting better or the installs are) and it all works 
fine
for me. I used Adept Manager to install everything. You installed numpy? I'm 
running
kubuntu.

 Hi people
 
 I'm trying to use matplotlib, ipython and xubuntu(gusty) all together. 
 Whenever I try to run ipython with -pylab tab, nothing extra happens to 
 the start up screen and pylab hasn't been imported. I have managed to 
 sucessfull install ipython and matplotlib on a Redhat system and ipython 
   -pylab works. ipython and matplotlib work btw
 
 I've tried install from source, apt and easy_install all to to avail
 
 Can anyone suggest what I am doing wrong or an output to post to show 
 more details of what is happening on my machine
 
 Thanks
 
 Andy

Re: [Matplotlib-users] matplotlib, ipython and ubuntu

Hello!

 Hmm, I did reinstall and still no joy, it insists on install python2.4 
 at the same time!
do a
$: sudo apt-get --purge remove matplotlib ipython
to really remove the configuration files. then
$: sudo apt-get install matplotlib ipython
check if pylab is on your system:
$: locate pylab

Here are the contents of pylab:
from matplotlib.pylab import *

so you may just test this in a python shell:

$ python
Python 2.5.1 (r251:54863, Oct  5 2007, 13:36:32)
[GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2
Type help, copyright, credits or license for more information.
  from matplotlib.pylab import *
 

then do the same from within ipython as I'd shown in my previous mail.

I hope that this helps you to narrow it down.

I have also some troubles with ipython that is currently in Gutsy:
  ipython
Python 2.5.1 (r251:54863, Oct  5 2007, 13:36:32)
Type copyright, credits or license for more information.

object? - Details about 'object'. ?object also works, ?? prints more.

Very strange.  I can't reproduce it here (on gutsy, but running
ipython from my own tree). What's odd is this:

In [1]: import Numeric

In [2]: print Numeric.ArrayType
type 'array'


So Numeric *most definitely* has an ArrayType member. Try doing the
same as I did, also showing us whether you started ipython with -pylab
or not.  There may be something odd about your Numeric installation.
Also do this:

In [3]: Numeric?
Type:   module
Base Class: type 'module'
Namespace:  Interactive
File:   /usr/lib/python2.5/site-packages/Numeric/Numeric.py

[etc]

It's possible that you have in your path a file called Numeric.py
which is not the 'real' Numeric module.  This would explain your
problem and why nobody else sees it.

Cheers,

f
