Most people use it interactively, or for long running programs. Import times only matters for interactive commands depending on numpy. > > and I am not saying to change this code.

It was a merge from a (at the time) experimental branch. I can't remove it now because my company does not allow subversion access, but I will fix this tonight.

You are supposed to run the tests on an installed numpy, not in the sources: import numpy numpy.test(verbose = 10) You can't really use run numpy without it to be installed first (which is what the message is about). cheers, David _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
