❓ Question

from nes_py.wrappers import JoypadSpace import gym_super_mario_bros from gym_super_mario_bros.actions import SIMPLE_MOVEMENT import gym

Import Frame Stacker Wrapper and GrayScaling Wrapper

from gym.wrappers import GrayScaleObservation

Import Vectorization Wrappers

from stable_baselines3.common.vec_env import VecFrameStack, DummyVecEnv

Import Matplotlib to show the impact of frame stacking

from matplotlib import pyplot as plt

from nes_py.wrappers import JoypadSpace import gym_super_mario_bros from gym_super_mario_bros.actions import SIMPLE_MOVEMENT

env = gym_super_mario_bros.make('SuperMarioBros-v0') env = JoypadSpace(env, SIMPLE_MOVEMENT) env = GrayScaleObservation(env, keep_dim=True)

when i execute the line mentioned below:

4. Wrap inside the Dummy Environment

env = DummyVecEnv([lambda: env])

i got this error

Checklist

[X] I have checked that there is no similar issue in the repo
[X] I have read the documentation
[X] If code there is, it is minimal and working
[X] If code there is, it is formatted using the markdown code blocks for both code and stack traces.

It seems like you're using a custom env. So, please fill the custom env issue template completely.

I'm new to this and I really didn't get it. Im using virtual environment with python3.11. I saw a tutorial on the web I followed along.

Closing as the issue template was not filled properly, also seems to be related to a custom env, not SB3.

Bro I just solved this problem by reinstalling an old version of stable-baselines3. You can try: pip install stable-baselines3[extra]==1.4.0
