[sage-support] Help on creating packages/modules
Dear Supporters,
I am about to create a sage package pGroupcohomology comprising
several (extension) modules mtx, resolution, ...
From various Python and Cython manual pages, I thought that I ought to
write the following in my setup.py:
packages=[pGroupCohomology],
ext_package=pGroupCohomology, # Here I am not sure: Necessary?
ext_modules=[
Extension(pGroupCohomology.mtx, ...),
Extension(pGroupCohomology.resolution,...)], ...
After installation, the following works:
sage: from pGroupCohomolog.mtx import MTX
sage: M=MTX('some data')
I can do computations with M. But M does not know where it belongs to:
sage: M.__class__
mtx.MTX class instance at ...
I am puzzled by the fact that it says mtx.MTX and not
pGroupCohomology.mtx.MTX, which also makes pickling fail.
Can you tell me why the above setup does not yield the desired package
structure?
Best regards,
Simon

Yes (and please excuse that I wrote both to Cython-dev and Sage- devel). - In SAGE_LOCAL/lib/python2.5/site-packages/ I have a folder pGroupCohomology. - It contains __init__.py, mtx.so and some other .so - When I wrote my original post, I accidentally had another copy of mtx.so in the site-packages folder (not a subfolder). I removed it, and now the pickling error is a bit different: PicklingError: Can't pickle mtx.MTX_unpickle_class: import of module mtx failed Explanation of the Pickling errors: 1 The module pGroupCohomology.mtx believes that it is simply mtx, without being contained in a package. 2 Hence, when pickling, the MTX_unpickle_class is looked up in mtx (not pGroupCohomology.mtx). 3 When there was an abandoned mtx.so in the site-packages, it was possible to find mtx.MTX_unpickle_class, but of course it was not identic with pGroupCohomology.mtx.MTX_unpickle_class --- this explains the error message from my first post 4 Now, there is no mtx.so in the site-packages (only in a sub-folder). Hence, looking up mtx.MTX_unpickle_class fails, therefore the new error message. Anyway. It seems the key problem is that the modules in the package pGroupCohomology are unaware that they belong to a package. And I have no clue why.

And I have no clue why. The thread here seems relevant: http://www.mail-archive.com/cython-...@codespeak.net/msg02790.html It starts with the same observation that when a cython module foo with a class Foo is part of a package pkg then one has pkg.foo.Foo ().__module__ == 'foo', while it should be == 'pkg.foo'. It is also said (if I understand correctly) that it is a pyrex vs. cython issue. The difference is that the poster also wants to be able to fix the fully qualified module name at run time, not at compile time. I would be happy to fix the fully qualified module name at compile time --- but I don't know how, since Cython apparently gets it wrong. Meanwhile I wonder how all the extension modules in Sage get their fully qualified names. After Robert's advice off list, I changed the folder names in my sources so that it reflects the intended package- module structure. Now I have spkg-install src/ setup.py pGroupCohomology/ (before, i used CohoSrc/) __init__.py mtx.pyx ... In setup.py, I have name=pGroupCohomology, packages=[pGroupCohomology], ext_modules=[...

And I don't see a fundamental difference to all the 100s extensions in Sage. Is setup.py not the right place to determine the package-module structure? Is it needed to hard-code the fully qualified name into mtx.pyx? But how?

[sage-support] @parallel() globals problem
I don't see many posts about the @parallel decorator, but I'm having a problem that I would think would be pretty common. I want to decorate a function that performs some action with an instantiated class and returns the results of that class method, but when I try to execute the generator returned from the decorated function, I get an error that the 'global' class cannot be found. Here's an example: class foo(): def do_something(self, myargs): return myargs @parallel() def f(N): a = foo() return a.do_something(N) g=f([1,2,3,4]) list(g) --- NameError Traceback (most recent call last) /home/jlh/ipython console in module() /usr/local/sage-3.4.1/local/lib/python2.5/site-packages/sage/parallel/ multiprocessing.pyc in parallel_iter(processes, f, inputs) /usr/local/sage-3.4.1/local/lib/python2.5/site-packages/processing/ pool.pyc in next(self, timeout) NameError: global name 'foo' is not defined sage: So anyway, the only examples I've found of sage + @parallel use functions that don't instantiate a user class. They just use like def f(N): return N^2 and so on. Thanks for any pointers to docs or examples that might help me use this decorator.

Look at the file ~/.sage/ipython/ipythonrc (search for color). * Output automatically pretty-printed and centered Ewww :-} If `twere to be done, I'd prefer the default to be off. This isn't automatic, but some pretty-printing can occur: sage: f=x^2 sage: f x^2 sage: print f 2 x But note this: sage: Zx.x=PolynomialRing(ZZ); sage: f=x^2 sage: f x^2 sage: print f x^2 The former behavior comes from the symbolic ring support, which is currently handled by maxima (and is therefore subject to change). * (This is a more general Sage issue): when a variable is defined, as in x=sqrt(y^2+1) it is automatically printed to the screen, unless the user requests otherwise (say, with a semi-colon) Like Alex, I prefer the current behavior, so again, if done, I'd prefer it default to off. Is there any easy way of coercing Sage to act like this? I don't think so, beyond what's mentioned in this thread; someone who really knows may be able to be more specific. HTH Justin -- Justin C.

[sage-support] Re: installing binary of sage-3.4.1 OSX10.4 on G4
When I say I cannot move the sage folder, I mean, it just jumps back into the .dmg package with NO complaints or error messages. I have no evidence of any problem with my OSX (I downloaded 3.4 about 3 or 4 weeks ago with no problems). I also re- downloaded both with Firefox and with Safari. Always the same result. The README.text file includes ** WARNING ** If you get an error copying the folder do the following: Do not drag the the folder out of the dmg image. Use the shell (via Terminal) and do a cp -R -P /Volumes/sage-2.9.2-OSX10.4-intel-i386-Darwin/sage . from the location where you want to install to. Adjust the name of the Volume as needed. This is why I think there may be a mix-up, since the G4 is NOT an Intel machine...

Yes, I read that already. How does that manifest itself? Do you get an error message? Is the folder not selectable? etc. Also, the only to move this non-working .dmg into the trash is to force Finder to quit and restart! It sounds like your local install of OSX is either broken or the dmg you downloaded has been corrupted during the download (assuming the upload worked when placing it on the sever). Have you verified the md5sum that is posted with the binary right on the download page? Thank you.

Look in Console (in your Utilities Folder - cmd-shift-u). There might be something related in there.
