Jupyter notebook will not import matplotlib although it appears to be installed

Question

in:

import matplotlib.pyplot as plt
%matplotlib inline

df.plot()

Gives:

ImportError: matplotlib is required for plotting.

I installed matplotlib through pip, and showing it gives:

Location: c:\users\miscs\appdata\local\programs\python\python36\lib\site-packages

in Jupyter, sys.executable outputs:

'C:\\Users\\miscs\\AppData\\Local\\Programs\\Python\\Python36\\python.exe'

Why is this error occurring and how can I fix it?

Just ran into the same error, resolved it thus:

I did pip install matplotlib in my virtualenv, and then I ran import matplotlib which succeeded, but the df.plot() step still gave me the ImportError: matplotlib is required for plotting. error.

Saved my Jupyter notebook, killed and restarted the Jupyter notebook server, and reopened the notebook. Didn't face the error again.

I guess matplotlib needs to be installed and available before the notebook is started.
