Conservative Q-Learning (CQL)

PyTorch implementation of the CQL algorithm (Paper). Including the discrete action space DQN-CQL version, the continuous action space SAC-CQL version and a discrete CQL-SAC implementation.

Setup

-> conda environment [ ] -> requirement.txt [ ]

Run

Select the folder [CQL-DQN, CQL-SAC, CQL-SAC-discrete] of the algorithm you want to train and run: python train.py
