Public bug reported:
Binary package hint: python-numpy
I am writing an application that embeds python and invokes scripts that
import numpy. I have found that while numpy will import correctly the
first time, if I run Py_Finalize() and then reinitialize the python
interpreter, the second time numpy is imported I get this error:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/local/lib/rtxi/rtxilib.py", line 3, in <module>
from numpy import ndarray, array, empty
File "/usr/lib/python2.5/site-packages/numpy/__init__.py", line 36, in
<module>
import core
File "/usr/lib/python2.5/site-packages/numpy/core/__init__.py", line 5, in
<module>
import multiarray
SystemError: dynamic module not initialized properly
The workaround is to simply skip the call to Py_Finalize(). This problem was
discussed on the scipy mailing list previously:
