I ran into issues with some python files from Udacity course in Machine Learning. The file uses the Tk library, which gives an error 'TclError'. I followed some online advice:
I found that I have installed the tk both in anacode and system. But I donot know the reason in callback in Tk. So what I did is change the backend of matplotlib.
backend : TkAgg to
backend : Qt4Agg And it worked for me !
Worked for me too!
