recv disconnected

[picksh]

hi, I have met the problem that when I run python3 -m minos.tools.pygame_client --dataset mp3d --scene_ids 17DRP5sb8fy --env_config pointgoal_mp3d_s, it can be connected but receive disconnected immediately. I don't known how to handle this problem and do you have some suggestions? Thank you!
I use the master branch.
