docker容器内运行python多进程卡住

在启动多进程的文件头部执行如下代码即可：

import multiprocessing as mp

try:
   mp.set_start_method('spawn', force=True)
   print("spawned")
except RuntimeError:
   pass

参考：

multiprocessing - mp.set_start_method('spawn') triggered an error saying the context is already been set - Stack Overflow
