我正在使用ray并行运行pygame,但希望如此抑制 SDL 视频警告/错误。
这是我的代码:
@ray.remote
def run2(agent): # same as run1
sys.stdout = open(os.devnull, "w")
sys.stderr = open(os.devnull, "w")
os.environ["SDL_VIDEODRIVER"] = "dummy"
env = GameEnv(0)
state = env.reset()
steps =0
done= False
while not done:
steps+=1
action = agent.predict(state)
ns , r ,done ,i= env.step(env.action_space.sample())
return steps
# note: maybe run this twice to warmup the system
%time result = ray.get([run2.remote(pops[i]) for i in range(10)])

我曾尝试更改 stdout 和 stderr 但这似乎不起作用,或者我应该在其他地方更改它这是我为每个工人收到的警告

有没有办法使用光线参数或全局标准输出块来做到这一点?
发现你可以使用:
ray.init(log_to_driver=False)
