How are you trying to import it? What error message do you get? — Chathan Driehuys

@ChathanDriehuys well just open the python script from the terminal and import numpy Python 2.7.10 (default, Nov 27 2015, 18:37:43) [GCC 4.8.4] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import numpy Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named numpy — Squart

@Squart I just installed numpy using apt-get install python-numpy and didn't get the import error you did. My apt-cache looks identical to yours so I have no idea what's going on. Sorry. — Chathan Driehuys

From the comment I find that your local build of python is installed in /usr/local/bin and then does not have access to packages (like numpy) installed system-wide.

So try using:

/usr/bin/python -c "import numpy"
