An error message about multiple processes

[0batsy0]

When I use pycharm to run code，I received an error report，It seems to be underlying multiprocess code：

Can you try disabling multiprocessing in phoebe (either by calling phoebe.multiprocessing_off() immediately after importing or by setting the enviroment variable PHOEBE_MULTIPROC_NPROCS=0) and let us know if that fixes the issue?

Thank you for your reply.Does a program work normally without multiple processes, which means it can only work in a single process? Is there any way to solve this situation?

Yes, phoebe can work serially or using MPI instead. The multiprocessing (which is on by default) seems to be incompatible with a few different setups, so the easiest option is to just disable it.
