Hey there!

I ran my python script from python it runs just fine. I tried running through python-shell with v2.7 and v3.6 of python and I get the same error. I read through your issues and it looks like I don't need to do anything special to import python libraries python-shell does all the heavy lifting. I'm at a loss for how to proceed.

Error

I have the same issue. Did you fix it ? Thanks a lot
