mac selfplay 每步很慢，需要几十秒

reneix commented 6 years ago

mac 10.13.3 python run.py --type distribute --distributed self

distribute.py: class PlayConfig: def init(self): self.max_processes = 1 # tune this to your cpu cores self.search_threads = 10 # increase this will be faster but with weaker performance

agent/player.py line 179: self.all_done.acquire(True) 发现这里每次调用时间很长，几百ms。去掉该调用之后，发现以下错误。走几步之后程序会退出。

请问这个all_done.acquire 是用来同步 MCTS_search 搜索状态的么？

是的。Mac很慢是正常的，因为只能用CPU来跑。

这个加锁是在循环里面调用的，没有看到release，求问这个是用来同步什么状态的么？

release在这里，保证这一批搜索都结束再开始下一批。 https://github.com/NeymarL/ChineseChess-AlphaZero/blob/eab27f28fb7371ad15508fd433857af4e257b347/cchess_alphazero/agent/player.py#L370-L374
