在训练时，模型一直在跑，没有结果，日志也不更新，想请教一下可能的问题。

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.

    To fix this issue, refer to the "Safe importing of main module"
    section in https://docs.python.org/3/library/multiprocessing.html

run_longExp.py文件后导入完包以后加上那句 if ：这一行就行了，下面全部代码缩进到if里面就可以跑了
