Solution to the issue with multiprocessing AttributeError: Can't get attribute 'file_process' on <module '__main__' (built-in)>

Got this error and found a solution: Move file_process() to a different file then import it in main.py. Not sure if this issue happens to others. Just post this issue here for reference.

@LiangHsunChen out of curiosity - how did you encounter the error?
What code produced this behavior?

Neither calling the tool directly via CLI, nor by importing it into a 3rd party script gave me that kind of error

I had the same error, could be due to Mac?

If it's just Mac related, I'm open to patches, but will not work on it, as I have no Mac anywhere close.
So far this tool is Linux only (as stated in the metadata)
