jupyter notebook import error: no module named ‘matplotlib’

First, list your conda environments:

C:\Users\Felix>conda info --envs
# conda environments:
#
ipykernel_py2            D:\Anaconda\envs\ipykernel_py2
root                  *  D:\Anaconda

Next, activate your python 2 environment using source activate (Linux/OSX) or activate (Windows):

C:\Users\Felix>activate ipykernel_py2

(ipykernel_py2) C:\Users\Felix>

Finally, use pip to install the required packages:

(ipykernel_py2) C:\Users\Felix>pip install matplotlib
Collecting matplotlib
...
Successfully installed matplotlib-2.0.0

Hope that this helps.
