请问Multiworkers支持怎么开启？

在知乎上看到可以开启multiworkers进行探索，但是不知道在哪里可以开启这个功能？

Set args.num_worker in the code to a value greater than 1, and enable multi-processing by setting if_single_process = False. This will enable multiple workers.

将代码中的 args.num_worker=4 设置为大于1 的数值，并且开启多进程 if_single_process = False ，multi-workers 就会开启

You can see the code for the multiple workers that are enabled in train/run.py.

开启的多个workers 的代码 可以看 train/run.py：
