Python - Numpy install and import Issue

Question

I've used pip to install the module numpy (sudo pip install numpy).This works fine.

When importing numpy for use in my own module i get several the following errors.

 Traceback (most recent call last):
  File "<pyshell#65>", line 1, in <module>
    import numpy
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/numpy/__init__.py", line 180, in <module>

ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/numpy/core/multiarray.so, 2): Symbol not found: _PyBuffer_Type

  Expected in: flat namespace

I'm assuming the error has something to do with the multiarray.so file. I've tried turning it off and on (uninstall re install) and adding the where pip initially saves the module to python export path

(export PYTHONPATH="usr/local/lib/python2.7/site-packages")

doesn't seem to work.

Using which python in terminal gives me Python 2.7.6**, however I downloaded python 3.5 off of the site.

Answer 1

Issue resolved.

The reason i was having installation issues with pip, was down to the fact (thanks pv) that i was using the command:

"pip install moduleName"

rather than

"pip3.5 install moduleName"

this caused all sorts of complications, because i'm running python 3.5 and the "pip" command is for 2.7.

Thanks again.
