DQN Agent playing MountainCar-v0

This is a trained model of a DQN agent playing MountainCar-v0 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

# Download model and save it into the logs/ folder
python -m rl_zoo3.load_from_hub --algo dqn --env MountainCar-v0 -orga sb3 -f logs/
python enjoy.py --algo dqn --env MountainCar-v0  -f logs/

Training (with the RL Zoo)

python train.py --algo dqn --env MountainCar-v0 -f logs/
# Upload the model and generate video (when possible)
python -m rl_zoo3.push_to_hub --algo dqn --env MountainCar-v0 -f logs/ -orga sb3
