进程创建后不能启动

[silkyrose]

主程序main-makespan.py在windows下执行 已增加： if name == 'main': freeze_support() 可以看到Process创建了13个进程，但是第一进程就不能start() 报错说它不能转换为数值

 for i in range(n_episode):
     algorithm = RLAlgorithm(agent, reward_giver, features_extract_func=features_extract_func,
                             features_normalize_func=features_normalize_func)
     episode = Episode(machine_configs, jobs_configs, algorithm, None)
     algorithm.reward_giver.attach(episode.simulation)
     p = Process(target=multiprocessing_run,
                 args=(episode, trajectories, makespans, average_completions, average_slowdowns))
     p.start()
     p.join()

我也遇到了这个问题，请问你解决了吗？

[silkyrose]

你好： 我还没有解决，你呢？ p.start() return convert_to_tensor, (self._numpy(),)ValueError: Cannot convert a Tensor of dtype resource to a NumPy array.

我改成用单进程去运行了

[silkyrose]

我知道是哪里的问题，episode这个对象不能作为process函数的参数传进去。但是我不会改，试图把episode转换为json字符串，在multiprocess函数里面再转回为对象，但是没成功

请问是怎样操作的？
