Why do you want to use Pycharm?
I guess, you are either want to use it as your standalone IDE, then this is the solution for you. It simply syncs back and forth between the notebook version and the Pycharm plain python version (think it like a dropbox between two ends, they are the same code in 2 IDEs)
Or you want only the debugging power of Pycharm. Then this is the solution for you.
