SAC Agent playing seals/HalfCheetah-v1

This is a trained model of a SAC agent playing seals/HalfCheetah-v1 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
SB3: https://github.com/DLR-RM/stable-baselines3
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 sac --env seals/HalfCheetah-v1 -orga HumanCompatibleAI -f logs/
python -m rl_zoo3.enjoy --algo sac --env seals/HalfCheetah-v1  -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 sac --env seals/HalfCheetah-v1 -orga HumanCompatibleAI -f logs/
python -m rl_zoo3.enjoy --algo sac --env seals/HalfCheetah-v1  -f logs/

Training (with the RL Zoo)

python -m rl_zoo3.train --algo sac --env seals/HalfCheetah-v1 -f logs/
# Upload the model and generate video (when possible)
python -m rl_zoo3.push_to_hub --algo sac --env seals/HalfCheetah-v1 -f logs/ -orga HumanCompatibleAI
