Question

I just installed scipy and numpy using homebrew and pip. I did the following:

brew install python
brew install gfortran
easy_install pip
sudo pip install numpy
sudo pip install scipy

numpy and scipy are both easily found in /Library/Python/2.7/site-packages, but when I open a python shell in the terminal and type:

import numpy
import scipy

I get:

Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
ImportError: No module named numpy

and the same for scipy. What’s wrong? Pip seems to think they’re installed.

Answer 1

The python shell you are running from the terminal is probably OSX pre-bundled python and not the one you installed (with numpy & scipy).

You can list the current paths using:

import sys
print(sys.path)
