All workers' actions are "idle". Does it make sense?

[XinWang0219]

Describe the bug
During training, all workers' actions are "idle". Does it make sense? Or do I do something wrong in the steps before?

To Reproduce
Steps to reproduce the behavior:

1. After run "poker_ai cluster", get two files "card_info_lut.joblib" and "centroids.joblib".
2. I create directory "./research/blueprint_algo" and put these files in it.
3. Then run "poker_ai train start --lut_path ./research/blueprint_algo --sync_cfr --sync_discount --sync_serialise"

Expected behavior
I don't know whether these 'Woker-i': 'idle' are what they should be. But while I run "poker_ai play" and get "UnboundLocalError: local variable 'action' referenced before assignment", I think it may be because 'idle' is not in the expected choices of actions.

请问这个问题您解决了吗 我也是都是idle
Have you solved this problem? I am also idle

这个空闲应该不是不做事情，而是为了同步多个进程的资源。
用确保所有的工作进程（workers）在开始同步任务之前都处于闲置状态。这样做是为了避免在同步任务执行期间发生资源竞争或数据冲突。
