Getting error while testing

I am able to train policies.
But when loading the checkpoint to 'play' I am getting the following error :
AttributeError: 'Envpool' object has no attribute 'render'

The command I am running is :
python3 runner.py --play -c runs/Walker2d-v4_envpool_30-07-00-39/nn/last_Walker2d-v4_envpool_ep_1000_rew__5242.4565_.pth --file ./rl_games/configs/mujoco/walker2d_envpool.yaml

I tried searching for a solution and it looks like a problem with gym.

I am not sure if adding time is the best or recommended way?

Thats a reason why I switch to the gym version of the mujoco to use render.
Could you set render to false in the config? Currently it is true/
player:
render: True
AFAIK envpool doesn't support rendering at all.

Thanks a lot for the reply! Any workaround?

If you want to render your policy you can reuse same checkpoint but with config with regular mojuco gym. And don't forget set render:True in yaml.

Hey @Denys88 do you have support for the opensource mujoco. Currently, the player calls gym.envs.mujoco.mujoco_env, which calls mujoco_py (old mujoco). How can I call the latest version of mujoco, which is not dependent on gym
