[Numpy-discussion] crashes after switching to 1.3.x

[Adrian E. Feiguin]

Hi Todd,

Thank you for your reply. I have a completely new installation, there 
are no conflicts with previous installations.
I found that the problem is in import_libnumeric in libnumeric.h. It 
seems that the libnumeric_API is not initialized because it doesn't pass 
the line:

        PyObject *module = 
PyImport_ImportModule("numarray.libnumeric");     \
        if (module != NULL) 
{                                               \

Any ideas?
Thank you again,
<ADRIAN>
