python - Strange error while using Pycharm to debug PyQt gui

I've been using PyCharm to debug my gui in PyQt. This has been really successful thus far, until I've run into a strange error in trying to debug my gui just now. I've set a breakpoint at the beginning of the script as well as at various points but the program does not have a chance to get to this point. I've also tried removing all the breakpoints and running the debug but get the same result. The full traceback is:

                      ^

Process finished with exit code 1

Does anyone know what is causing this error and how it can be resolved? When I run the code normally (without debugging) I do not run into any of these errors.

I ran into the same issue, and it took me a while but I found a solution that works for me. I believe what happens, is that the debugger is looking for the module _pydevd_bundle.pydevd_cython in a directory code. However, because you are running the script out of your own code directory, the debugger checks your folder, sees their is no module, and throws the error. That would explain why deleting the __init__.py works, because the debugger won't confuse the two directories anymore.

So, renaming your code directory to something else, should fix the issue and let you keep the init file.
