When I try to run the colab example with the A2C algorithm on an Atari env, I get the following error:

`--------------------------------------------------------------------------- ConnectionResetError Traceback (most recent call last) in () ----> 1 env = make_atari_env('Boxing-v0', num_env=4, seed=0) 2 # Stack 4 frames 3 env = VecFrameStack(env, n_stack=4)
