sudo pip install matplotlib

When I go ahead the import that library in python. python says it could not find the modulus.

python3.5 -c 'import matplotlib; print(matplotlib.__version__, matplotlib.__file__)'

Traceback (most recent call last): File "", line 1, in ImportError: No module named 'matplotlib'

How can I fix this?

All the pip messages concern python 2.7, you are using python3.5, you are running the wrong version of pip or pip in a 2.7 environment. Install matplotlib in your 3.5 directory. – cdarke
I have no idea how 3.5 was installed, and what your path names are. Find the pip for 3.5 and run that by specifying the full hierarchic name. If you don't know what that is then ask whoever installed 3.5. – cdarke

You need to install those libraries for the same version of python that you are using later to execute your code.

So if you want to use Python 2.7 you have to call

sudo pip2 install matplotlib

When using python 3.5 use it in a similar way

sudo pip3 install matplotlib
