run problem about koopa HOT 3 CLOSED

I already solved this problem.Because my ps uses windows system, so I need to change the parameter num_workers=0.

from koopa.

Could you please give more details about how you run the run.py?
It is not recommended to run the run.py using python run.py directly. Instead, you could refer to bash script in scripts folder.

from koopa.

when I use the bash scripts,terminal shows

RuntimeError:
An attempt has been made to start a new process before the
current process has finished its bootstrapping phase.

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...

    The "freeze_support()" line can be omitted if the program
    is not going to be frozen to produce an executable.

just like I used python run.py to run the run.py directle
It shows same problem.
