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.
