No module named 'mpl_toolkits' Error in Spyder-4.0.1

[Stephen P. Molnar]

I have installed Spyder-4.0.1 in ~/Anaconda3/envs/Spyder4 on my Debian-10.0.1 Platform.

When I run a Python Script, that ran without any problems in Spyder3, I encounter the "No module named 'mpl_toolkits' "  message which is module not found error.  Code Analysis finds:

E0401: 10,0: : Unable to import 'mpl_toolkits.axes_grid1'

E0401: 11,0: : Unable to import 'mpl_toolkits.axisartist'

E0401: 12,0: : Unable to import 'matplotlib.pyplot'

My attempts to find the missing module have resulted in failure.

What am I doing, or failing to do, to resolve the problem?

Thanks in advance
