import matplotlib.pyplot as plt -> error

I am getting the following error on the import line in the workspace for matplotlib:

ImportError: numpy.core.multiarray failed to import

Is there a reason this library will not import?

It appears that numpy.core.multiarray failed to import. Can you confirm if numpy is installed in your environment?

Can you start the Python REPL and import numpy? This should be error free:

$ python
Python 3.6.3 (default, Oct  3 2017, 21:45:48) 
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
