[Numpy-discussion] [SciPy-Dev] Setting up a dev environment with conda

[Michael Sarahan]

Running tests in the folder might be causing your problem.  If it's trying
to import numpy, and numpy is a folder in your current folder, sometimes
you see errors like this.  The confusion is that Python treats folders
(packages) similarly to modules, and the resolution order sometimes bites
you.  Try cd'ing to a different folder (importantly, one NOT containing a
numpy folder!) and run the test command from there.

HTH,
Michael
