Hello,

I have just upgraded from SciPy 0.13.3 to 0.17.1 and Python scripts that used

to work don't work any more. The problem appears when I try to use the odeint

function. When I try this:

>>> from scipy.integrate import odeint

I get those following error messages:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/scipy/integrate/__init__.py", line 56, in <module>
from .odepack import *
File "/usr/local/lib/python2.7/dist-packages/scipy/integrate/odepack.py", line 6, in <module>
from . import _odepack
ImportError: /usr/local/lib/python2.7/dist-packages/scipy/integrate/_odepack.so: undefined symbol: lsoda_

The command above always worked fine with SciPy 0.13.3. Is this error somehow

related to Numpy or Lapack (sorry if this question makes no sense, but I'm

really lost)? Is there any test I could do?

Despite this error the whole SciPy module/package seems to import OK:

>>> import scipy
>>> print scipy.__version__
0.17.1
>>>

I'm running Ubuntu 14.04 64-bits with Python 2.7.6, gcc 4.8.4 and Numpy 1.11.0.

Thanks in advance for any help you provide.

Fausto
