[Numpy-discussion] numpy.test() fails if it runs after scipy.test()

[Christopher Burns]

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.
