[Python-modules-team] Bug#495457: python-numpy: Error while loading a library

[Christophe Combelles]

Package: python-numpy
Version: 1:1.1.0-3
Severity: normal


I get an error while trying to 'import svm'.
libsvm is installed from source:
http://scipy.org/svn/scikits/trunk/scikits/learn/scikits/learn/machine/svm/

>>> import svm
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.5/site-packages/svm/__init__.py", line 62, in <module>
    from classification import *
  File "/usr/lib/python2.5/site-packages/svm/classification.py", line 5, in
<module>
    from model import Model
  File "/usr/lib/python2.5/site-packages/svm/model.py", line 3, in <module>
    from dataset import PrecomputedDataSet
  File "/usr/lib/python2.5/site-packages/svm/dataset.py", line 3, in <module>
    import libsvm
  File "/usr/lib/python2.5/site-packages/svm/libsvm.py", line 15, in <module>
    _libsvm = N.ctypeslib.load_library('libsvm_%s' % so_ext, __file__)
  File "/usr/lib/python2.5/site-packages/numpy/ctypeslib.py", line 48, in
load_library
    for ln in libname_ext:
UnboundLocalError: local variable 'libname_ext' referenced before assignment


In numpy/ctypeslib.py, libname_ext is defined in a within a 'if' statement:
     if '.' not in libname
If the condition is not satisfied, libname_ext is not defined although it is
used on line 48, thus leading to the error.

In my case, the name of the lib is 'libsvm_.so'.
