OS X (MacBook Pro; Intel) FiPy installation problems

[fipymigrate]

Hi guys,

I installed (apparently) FiPy in my PowerBook Pro. However, when I try running one of the examples, I get the message:

adamantium:~/Installs/FiPy-1.2 edwin$ python examples/diffusion/mesh1D.py
Traceback (most recent call last):

File "fipy/tools/sparseMatrix.py", line 322, in addAt
self.matrix.update_add_at(vector, id1, id2)
TypeError: No array interface and array method not returning Numeric array.

I installed PySparse from the tar ball. In the process, I edited setup.py and set use_numpy to False because it was NOT compiling. Does this have to do anything with the behavior that I am experiencing? I am using python 2.4. When I installed FiPy I did NOT get any complaints.

I ran then all the tests, and I got 64 failures (too many to post here).

I would appreciate any help.

Thanks!,

Edwin

The problem is that you are using the old Numeric with pysparse, but the new numpy
with fipy (doesn't work). The reason that pysparse didn't compile with numpy is that at the moment numpy is not putting the header files in the correct place. I put out a mail to the pysparse list, but, because technology sucks, I can't access it on sourceforge. Anyway, to fix your problem copy the header files from:

/pythonBasePath/site-packages/python/numpy/core/include/

to

Include/Lib/numpy

in your working copy of pysparse and switch use_numpy to True.
