Description： My RL Env is laikago env which copy from https://github.com/erwincoumans/motion_imitation. So my probelm is that when I visualize my trainning process and timesteps reach 6m~7m, my visualization would be suspended: the robot seems frozen and windows does not have any changes, but meanwhile process still is alive.
