double free or corruption (!prev)
from garage.envs import GymEnv import gym import gym.wrappers import gym.envs.atari import copy env = gym.envs.atari.AtariEnv('breakout') env.spec = gym.envs.registration.EnvSpec('NoFrameskip-v0') env = gym.wrappers.AtariPreprocessing(env) env = GymEnv(env, max_episode_length=1000) copy.deepcopy(env) copy.deepcopy(env)
The issue only occurs on the second deepcopy.
