PyCharm and Brian2 - code runs through when running the script normally but not in debugging mode

Hey,

I'm working with brian2 (https://github.com/brian-team/brian2) in PyCharm 2017.3.2. So far everyhing worked fine until I wanted to track every step in my code using PyCharms debugger mode. Though my code runs through when I simply run my code, it throws an error when I use the debugging mode. 

I explained the problem in detail here: https://github.com/brian-team/brian2/issues/909

I'd appreciate it a lot if you guys could help me! I have no idea what goes wrong and I really need to understand what is going on my code.

Thanks a lot in advance!
Sven
