Everything works as supposed to on the Django development server. In Apache, the django app also works except when matplotlib is used. Here’s the error I get: 

No module named multiarray.

Exception Type: ImportError 
Exception Value: No module named multiarray 
Exception Location: /usr/share/pyshared/numpy/core/numerictypes.py in <module>, line 81 
Python Executable: /usr/bin/python 
Python Version: 2.6.4

From the python shell, both statements work: import numpy.core.multiarray and import multiarray. Any ideas?
Thanks

As I’m looking over the numpy files, I found the multiarray module, which has an extension of ‘so’. My guess, is that mod_python is not reading these files.

    Problem solved. Here’s what I did.

    First of all, before I was getting the import error:

    “No module named multiarray.”

    I was getting an error like this:

    “: Failed to create /some/dir/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data”

    By adding the pyshared folder to the PythonPath variable, this error went away and I got the import error.

    So here’s how I fixed it:

    Removed the pyshared folder from the PythonPath variable.

    Before importing the matplotlib module, add these lines:

    import os
os.environ['HOME']='/some/writable/dir'

    Next, before import matplotlib.pyplot or pylab, add these lines:

    import matplotlib
matplotlib.use('Agg') 
# 'Agg' or whatever your backend is.

    This is documented here.

    That’s is! It’s working on python2.5 for me now. But I believe it’ll work on 2.6 as well.
