Please Help We are here to help, but in order to do that, it would help us to know what is going wrong. You have not given us much to go on. The following might help us: - what version of sage? - how did you install it (binary package from our website; similar from a package manager from your OS; compile from source)? - what hardware and OS (including OS version)? - how do you start sage (command line; notebook)? - what commands did you try, and what were the results.

Re: [sage-support] Memory issues when running simple program
FWIW, I ran this on a 2019 Mac Book Pro (8-core 2.4 GHz Core i9) with 64GB of
memory and ~4TB of disk.
The code thrashed the disk with more paging than I have seen in a long time
with this much disk. As Nils guesses, it’s the parametric_plot() call that
brings things to a halt. I finally killed it after about 4 hours.
Also, memory usage for this python process seemed to stabilize for the last 2-3
hours.

Well, perhaps Ubuntu has special mojo that would make that work, but on any Unix-like system I am aware of, what I saw in your attached snap of the command and output means to me that the command was expecting the file to be in the current directory. Nothing shows me that the command would know where in the world to look for the tarball other than locally. If it did work and now doesn’t, it’s beyond my experience. In your following message, you say “Unable to sagemath download pre-built binary from site”. Is that literal output from tar? It’s pretty weird phrasing, in the first place. And additionally, how does “it” know what the site is, and that the tarball contains a pre-built binary? Sorry I can’t be of more help. Justin -- Justin C.

It would help to know what “codes do not work” means. Do you get an error
message, or does the function f() not produce the result you want.
It may be that you do not have much experience with the Python programming
language. There is extensive documentation available at <https://python.org>.
In case your copy of the code you are writing was exactly what you used, the
problem may be that you are not following the indentation rules that Python
uses. This code, which is the same as yours, except for indentation, works for
me:
def f(i, v1):
v=[]
for j in v1:
v.append(j)
print(v)
v[i+1]=v1[i]
v[i]=v1[i+1]
return v

This generated the > arched crash log when attempting to launch via the Terminal I have roughly the same system as you, with 10.14.2. I have successfully installed the 8.5 “.app” from the DMG without issue (although I can’t seem to start sage in a terminal window). I have yet to install from the tarball, but it sounds like you unpacked the tarball and then tried to run “./sage”. Is that correct? If so, that does not work, because the tarball contains only source. To use it, you have to first build it, which, AFAIR, takes about 1-2 hours if you include testing. It also requires you to have the Xcode command-line tools installed. If you are not up for building from scratch, there should be a .dmg of a pre-built 8.5 version for 10.14 at the same place you got the .app version. That may work better for you. If some of that is unclear, or you want more pointers/info, reply back. There is also information available on the sagemath website. HTH Justin -- Justin C.

Re: [sage-support] different result from file or at prompt
Try returning the plot at the last line, and run the procedure again
return complex_plot(…)
I think the problem is that your procedure swallows the result of the plot.

Is this possible in sage? I doubt that there's a way to say "read this file" and have Sage provide a fully uncompressed and reformatted database for you (unless there is someone out there already working on this data). However, Sage is built on the programming language Python (v2.x right now), and you can do IO with the language. Check the documentation at <https://docs.python.org/2/library/index.html> (Sec 15.2 and possibly other places). You don't say how familiar you are with programming, Sage, and Python, so I stuck with the simple stuff. Ask here for more clarification, as needed. HTH Justin -- Justin C.

[sage-support] Development process
Hi, all, I have not done any real Sage development for a while (the last time, I think, there were wolves in Wales). I want to work on an existing Trac ticket, and I'm not clear on how to start this work. The ticket page gives me a branch (u/blah/branch-name). I am starting in a new, empty directory, and 'git' seems to want a repository specified. I have a "global" .gitconfig file set up. A couple of questions: Should I check out the 'develop' branch first, and then incorporate (how?) the branch on top, or should I check out the branch first, and then updated it (how?) to the develop branch? I have read the TentativeConventions page on the wiki, but it seems to be slightly outdated. Pointers, advice, etc. are more than welcome. Thanks in advance, Justin -- Justin C.

Re: [sage-support] PALP database for 4D reflexive polytopes?

If sage is installed on a multiuser system, in an admin/root-owned tree, you are stuck, I think. Check with the system admins.

Looks like a broken bash/sh script of some sort. "PS1" is the environment variable containing the shell prompt. The fact that the shell complains that "PS1: command not found" means that a script is trying to execute "PS1 ...". I would look for that string without a leading "$" (which would be needed for the shell to properly interpret it). Since this shows up right after the "last login" line, it appears this is in your startup sequence somewhere (see Volker's response). Was this the sage binary or the sage ".app"? HTH -- Justin C.

I don't know that recompiling would fix anything, but you could try. As for building, it is fairly simple (as long as nothing goes worng :-}). I just do "make" (with a "-j" factor to build in parallel; and if it breaks, take out the "-j", or cut down the number of threads).

If you type a full command name followed by . and then TAB, you get subcommands associated to that command/name. ?, ?? preceding or following a command or name (and then RETURN) will show you documentation for the command from the file where it is defined.

I found all files called macaulay2.py in the application
Sage-5.3-OSX-64bit-10.6.app and removed the -e from line 180.
If you remove the -e (see my comment earlier in the thread) you may need to
remove the stuff that follows, since that is supposed to be a command to the
M2 program. Can't say for sure what it does, but it might cause problems when
the line is given to a shell.
However, I don't think the -e is the problem.
I restarted my computer. Now I get the error:
TypeError: Unable to start macaulay2 because the command 'M2 --no-debug

Now I'm confused! I wonder if the other stuff (ZZ#{Standard etc) means
anything.
It surely does; I suspect it has something to do with 3+3.
I tried what you mentioned in your original post, and it worked (Mac OS X,
10.6.8). Perhaps the M2 interpreter is not in your default path. I know you
can run it from the command line, but you don't say how you do that.
Try this (assuming you don't have it set up similarly): make a symbolic link
from your M2 interpreter to /usr/bin (you may have to do this as root, e.g.,
with sudo):
$ ln -s /path/to/M2 /usr/bin/M2
and then try again. I don't think you have to restart your browser, but if it
doesn't work, do that and try again.

Any idea what is causing this mess up? I really need M2 to function in the

That command comes from line 180 in devel/sage/interfaces/macaulay2.py:

I have no idea what that -e does, but if you want to try removing it, that's
where you'd change something.
For the record, the -e allows the user to run Macaulay2 to evaluate an
expression that follows the -e on the command-line. You'd have to evaluate
that blather to figure out what the (bleep) was intended.

In my situation, length l of S is not fixed. Is there any method to solve this problem? This is the result of a feature of the Python language. 'T' is the name of an array, and acts like its address, so as you append T to S, you are continually reusing that same address.

The root of problem is that the explanation lies in the implementation details. The following is a rough sketch; the details are, well, details :-} To test whether something is an instance of a type, you have to have a specification for the type. When you modified the file that you previously attached, it was reloaded, and that action removed the old version and added the new version. The way types are maintained internally causes the isinstance() check to fail because, in fact, the old instance is not of the new type. Keep in mind that the internal code is not going to try to figure out that a newly-loaded version is different from the previous version; it's just out with the old; in with the new.

The documentation apparently needs to be fixed, at least as far as OS X is concerned. Oh, a few more things, in case people are reading this who aren't that familiar with the Terminal app and bash: you can give the command export SAGE_BROWSER='open -a /Applications/Firefox.app' at the shell prompt and it will have immediate effect, so you can test it right away. Second, if you instead change .bashrc, you should start a new terminal window for the changes to take effect. You can test whether it has done anything by typing 'export' and seeing if SAGE_BROWSER is listed with the appropriate setting. Thanks for your help, John. It turned out to be more complicated, trying to understand the deep mysteries of the bash shell and how Terminal is configured on my system. In spite of what the man page for bash says, Terminal seems to be ignoring the .bashrc file in my home directory, and instead reads .bash_profile. I was finally able to get Sage and notebook() to start Firefox by putting the export SAGE_BROWSER line into .bash_profile, not .bashrc. To clarify this, I believe that the man page says that .bash_profile is checked for a login shell, and that .bashrc is checked for a non-login, interactive shell.

Thanks, Mr. Curmudgeon ;-) That is indeed what I read in the man page, but my intuitive sense is that Terminal should open a non-login, interactive shell — after all, I am able to start entering UNIX commands interactively, and the shell does not prompt for a login. But when I actually try it out, the contents of .bashrc have no effect in Terminal/bash, but the contents of .bash_profile are processed. I conclude that something about a deeper understanding of Mac OS X and/or UNIX is eluding me. I think your confusion is in the use of the term login. Terminal starts a login shell for each window/tab that it opens, so your intuition needs a little polishing :-} Think of Terminal as a glorified xterm, in that all the windows belong to one Terminal, rather than each xterm owning one window. Login shells are represented (e.g., in 'ps' listings) with a leading - in the command name; and if you check a full ps listing, you'll see that the parent shell in each window (i.e., for each (pseudo)tty) has such a tag, and typically, no others do.

The doc tests say this is what the behavior should be, but I don't understand why. Is this actually the desired behavior and if so what am I misunderstanding? You're in the middle of a centuries-old debate, stemming from the Lagrange-Gauss smackdown (or maybe it was Legendre; it's been a while). The issue stems from the desire to equate quadratic forms and symmetric matrices (b*x0*x1 vs b/2*x0*x1+b/2*x1*x0). If you don't use the above, you end up having to deal with the ring ZZ[1/2].

I have to have the two functions separately for each matrix though just like my code above Definitely. You can do it roughly as your code snippets show, or there are built-in short-cuts depending on what you want to do. Here are a few: Q=deepcopy(U) # This copies everything Note that 1. if you use this inside a procedure, you have to import the name: from copy import deepcopy 2. if you use copy instead of deepcopy, you don't get what you might expect. Try this: Q=matrix(ZZ,6) U=Q U[1,1]=4 Q The reason is that more complex data types are copied by pointer (for speed); the deepcopy procedure actually makes a full copy, while copy just copies structure pointers, while the data values are shared between the copies. To find out more about using Sage as a program/scripting language, check out the documentation on http://sagemath.org and http://www.python.org. Python is the language used by Sage. Also, use expressions like matrix? to get on-line documentation on procedure/function/variable names; ?? gets both documentation and the code implementing the call (if possible; some built-in python things may not have code viewable). Finally, the TAB after a string will try to show you known names that begin with the string. If you type the full name of a class, followed by ., and then TAB, you will get a list of associated method, class variable, and instance variable names. You can then use the ? to find out more.

As you have discovered, if you type a partial string, TAB will give you completions that are known. TAB following the . will give you names of both methods (functions) and variables associated to the name you have just typed, as for E.. Not all names will work for a given instance; what will actually work depends on exactly how the instance was created (Sage is based on Python [see below], which has a good object structure underlying it). Also, once you have a complete name, ? and ?? will give you documentation (?) or documentation + implementation (if possible) (??) for the name. Try typing E?, once you have defined E as an elliptic curve (you get the same with Elliptic_Curcve?). It may also be helpful to review documentation on Python, and its class structures (see the documentation link on http://www.python.org). Python is the underlying language for both the Sage system and the Sage interpreter, so understanding that will help you to understand Sage. We don't put all of the possible details for all of Sage's functions and classes into documentation at any one time; Sage is dynamically changing, and to do so would be a lot of work. Instead, we rely on the above on-line mechanisms to supplement the documentation. A fair amount is automatically culled from source and put into various manuals (cf the documentation available in your installation, or on-line at http://sagemath.org). Finally (if you've gotten this far), your experience with mwrank shows that this is a method, i.e., a function/procedure. Typing E.mwrank? will give you information about how to use it.
