I'm getting the following error when running my iPython Notebook and was wondering if someone could help.
I have tried browsing in previous posts but couldn't find an answer. The noteboook does run in the end on the web browser but the error keeps appearing.
Error in console:

Any ideas? Thanks!
Update
Actually this error only happens when I run the jupyter/ipython notebook from the PyCharm editor. If I run it on a web browser the errors disappear. It seems PyCharm's notebook compatibility is still suffering from bugs...

I had the same problem after using PyCharm on a notebook.
I could make the error disappear in the browser by simply restarting the kernel, clearing all output and saving the notebook.
Restarting the kernel is done by going to the Kernal menu and then selecting Restart & Clear Output. See screenshot for an example:
