I've had that happen a few times, not really sure why it happens, but
there's an easy work around...

python setup.py develop
cd pyNastran
python all_tests.py

Also make sure you're running the right version.  The bug might be
caused by overwriting a previous version in site-packages.
python
import pyNastran
print pyNastran.__version__

It should say 0.4.1.  Let me know if it doesn't work properly.

 Dear Steven,

 

I have tried also  python all_tests.py, but it didn't run, because missed the wave module of scipy.

 

I had install this module, updated with some patch from science repository of Opensuse 11.4 x86.64

and now pyNastran 0.4.1. run fine.

 

Now, I'll try to use it.

 

thanks

Scipy.weave is a very strange module.   Scipy.weave is for embedding pure C code in Python, which is not even done in pyNastran.  It's actually only in pyNastran because pyNastran uses sparse matrices, which if you use sparse matrices without importing scipy.weave will erroneously return an error code of 0 if Python crashes.  How this happens is beyond me, but scipy.weave magically fixes the bug.

If enough people bug the scipy developers it might get fixed.
