TQC Agent playing BipedalWalkerHardcore-v3

This is a trained model of a TQC agent playing BipedalWalkerHardcore-v3 using the stable-baselines3 library and the RL Zoo.

The RL Zoo is a training framework for Stable Baselines3 reinforcement learning agents, with hyperparameter optimization and pre-trained agents included.

Usage (with SB3 RL Zoo)

RL Zoo: https://github.com/DLR-RM/rl-baselines3-zoo<br/> SB3: https://github.com/DLR-RM/stable-baselines3<br/> SB3 Contrib: https://github.com/Stable-Baselines-Team/stable-baselines3-contrib

Install the RL Zoo (with SB3 and SB3-Contrib):

pip install rl_zoo3

# Download model and save it into the logs/ folder
python -m rl_zoo3.load_from_hub --algo tqc --env BipedalWalkerHardcore-v3 -orga MattStammers -f logs/
python -m rl_zoo3.enjoy --algo tqc --env BipedalWalkerHardcore-v3  -f logs/

If you installed the RL Zoo3 via pip (pip install rl_zoo3), from anywhere you can do:

python -m rl_zoo3.load_from_hub --algo tqc --env BipedalWalkerHardcore-v3 -orga MattStammers -f logs/
python -m rl_zoo3.enjoy --algo tqc --env BipedalWalkerHardcore-v3  -f logs/

Training (with the RL Zoo)

python -m rl_zoo3.train --algo tqc --env BipedalWalkerHardcore-v3 -f logs/
# Upload the model and generate video (when possible)
python -m rl_zoo3.push_to_hub --algo tqc --env BipedalWalkerHardcore-v3 -f logs/ -orga MattStammers

This was my 6th attempt to crack this. I know it can be done with TD3 and SAC but not using sb3's basic implementation as I found out when I tried. Only the sb3 TQC implementation works
