Hi, I apologise if this question might seem a bit off-topic but the last I used oTree was while it was still on v3 and I have come back to it on PyCharm to try and reoperationalise a new experiment using the v5 version. 
Upon running the codes through the Python console to check coherence, I get the following error and I am not even where to begin fixing the "modulenotfound" errors. Any advice/help would be deeply appreciated!
Thanks!

Python console in PyCharm is somewhat broken with oTree 5 because PyCharm somehow assumes the project uses Django. Maybe if you start your project from scratch and copy-paste the app this error will go away. 

More concerning for me, debugging is broken and has been for a long time. I'm not sure but I'd give a lot for debugging in PyCharm to work again. Debugging with print() or breakpoint() isn't very fun.

Thanks for your swift reply @gmdcastillo. 
I'll have a try with your work-around and report back.

That is very problematic indeed because it now becomes extremely tedious to check coherences in the Python side of the code; it currently won't read the baseconstants, and so the code further down refers to C.someconstant, it won't read that either. 

I wonder what Chris thinks.
