Can't import VecFrameStackFrame from Stable-baselines3 – importing problem

Question

I have a problem when importing some dependencies from stable baselines 3 library, I installed it with this command

pip install stable-baselines3[extra]

But When I import my dependencies

import gym
from stable_baselines3 import A2C
from stable_baselines3.common.vec_env import VecFrameStackFrame
from stable_baselines3.common.evaluation import evaluate_policy
from stable_baselines3.common.env_util import make_atari_env
import os

I face this error

ImportError: cannot import name 'VecFrameStackFrame' from 'stable_baselines3.common.vec_env' (C:UsersUseranaconda3envsrl_learninglibsite-packagesstable_baselines3commonvec_env__init__.py)

Any advice?

Answer 1

I knew that stable baselines new version has changed the name from

from stable_baselines3.common.vec_env import VecFrameStackFrame

To

from stable_baselines3.common.vec_env import vec_frame_stack

and it worked for me
