numpy.test() fails if it runs after scipy.test()
Hi, I've got one failure if I run numpy.test() after running scipy.test() : ====================================================================== ERROR: Ticket #396 ---------------------------------------------------------------------- Traceback (most recent call last): File "/home/loic/tmp/Linux/lib/python2.5/site-packages/numpy/core/tests/test_regression.py", line 600, in check_poly1d_nan_roots self.failUnlessRaises(N.linalg.LinAlgError,getattr,p,"r") File "/home/loic/tmp/Linux/lib/python2.5/unittest.py", line 320, in failUnlessRaises callableObj(*args, **kwargs) File "/home/loic/tmp/Linux/lib/python2.5/site-packages/numpy/lib/polynomial.py", line 623, in __getattr__ return roots(self.coeffs) File "/home/loic/tmp/Linux/lib/python2.5/site-packages/numpy/lib/polynomial.py", line 124, in roots roots = _eigvals(A) File "/home/loic/tmp/Linux/lib/python2.5/site-packages/numpy/lib/polynomial.py", line 37, in _eigvals return eigvals(arg) File "/home/loic/tmp/Linux/lib/python2.5/site-packages/scipy/linalg/decomp.py", line 378, in eigvals return eig(a,b=b,left=0,right=0,overwrite_a=overwrite_a) File "/home/loic/tmp/Linux/lib/python2.5/site-packages/scipy/linalg/decomp.py", line 128, in eig a1 = asarray_chkfinite(a) File "/home/loic/tmp/Linux/lib/python2.5/site-packages/numpy/lib/function_base.py", line 398, in asarray_chkfinite raise ValueError, "array must not contain infs or NaNs" ValueError: array must not contain infs or NaNs But I've got no error if I begin with numpy test. I've seen that this Ticket #396 seems closed in Trac, should I reopen it ? for more information, I've attached the results of scipy.test and numpy.test . Regards, -- LB
Loic,
I was not able to reproduce this. Have you tried doing a clean
install by removing your numpy and scipy directories in the
site-packages and reinstalling. I've had old files in my install
directory cause problems in the past.
You are correct, the tests should not effect one another.

But I've got no error if I begin with numpy test. I've seen that this Ticket #396 seems closed in Trac, should I reopen it ?
for more information, I've attached the results of scipy.test and numpy.test.

That's very strange, I've made a local installation of numpy 1.0.4 and scipy 0.6 from official source, and I use the same kind of installation script as in http://www.scipy.org/Installing_SciPy/Linux/BuildingFromSource/GCC_1, so I always erase all the local directory to prevent this kind of conflict from happening. What's your configuration ? I'm under GNU/Linux debian lenny on a i686, and, I've just seen that this pb is already in the debian packages of my distribution, which are :
