[SciPy-user] SciPy autotester fails on pilutil

Hi all,



I am currently busy with SciPy 0.7.0 installation (I have NumPy v1.3.0
installed and PIL v).

If I run the scipy autotester (scipy.test()), I get the failure in testcase
from scipy.misc

ERROR: Failure: ImportError (No module named Image)

----------------------------------------------------------------------

Traceback (most recent call last):

  File
"/scratch/sources/numpy/nose-0.10.4-install/lib/python2.5/site-packages/nose/loader.py",
line 364, in loadTestsFromName     addr.filename, addr.module)

desc)

  File "/home/tgurzhiy/cadlib/scipy/misc/tests/test_pilutil.py", line 12, in
<module>

    import scipy.misc.pilutil as pilutil

  File
"/cadappl/python_scipy/0.7.0/python_scipy/lib/python2.5/site-packages/scipy/misc/pilutil.py",
line 10, in <module>     import Image

ImportError: No module named Image





In pilutil.py line 10 use import Image, the module Image is located in PIL.
In my case PYTHONPATH includes only directory (~/cadlib) that includes PIL,
NumPy, matloptlib and SciPy therefore module Image cannot be imported
directly if scipy.test() is ran.



As consequences of this error in pilutil, the functions from this file
cannot be used (e.g., imread, imshow, etc.)



>>> from scipy import misc

>>> im = misc.lena()

>>> im.shape

(512, 512)

>>> im1= misc.imresize(im,1.1)

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

AttributeError: 'module' object has no attribute 'imresize'



Why scipy/misc/pilutil.py uses direct import Image and not import PIL.Image?
The work-around could be to update my PYTHONPATH with ~/cadlib/PIL , but I
think it is not what should be done. Correct me if I am wrong.



Best regards,
