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.

During handling of the above exception, another exception occurred:

if you want to use multiple process at the same time, I recommend you to use the threading python library or other similar one if you really need to have multiple process you could use pathos library or subprocess or multiprocessing (keep in mind that pathos is kind a wrapper of multiprocessing library IIRC)

I can't help you having no context or code about your error
