ImportError :: Character not found: __PyErr_ReplaceException

I am using homebrew install python 2.7.10 and usr/local/bin/pythonlinked to python 2.7.10. But when I run my python code, an exception occurs as shown below. But when I use ipython import numpy, it goes well.

When I use a command in which python tells me what it /usr/local/bin/pythonis and use whereis python tells me what it is /usr/bin/python.

Traceback (most recent call last):

Try downgrading Python from 2.7.10 to 2.7.9, for example:

brew switch python 2.7.9

by overriding the existing one, since there seems to be a certain problem with 2.7.10.

For conda try: conda install python=2.7.9(according to this ).

PYTHONPATH, .

Python 3.
