from matplotlib import pyplot as plt

img = cv2.imread(\'pict         


        

Answer 1

The error has occurred due to the recent version of pyparsing being in conflict with matplotlib, which pip has picked up.

The workaround would be to: pip install pyparsing==2.1.1 followed by pip install matplotlib

Answer 2

It's a pyparsing issue:

Just wait for fix. Or you can upgrade python to 3.5

Answer 3

I had install the newest pyparsing(2.1.3) and this issue is fixed !
