Softlearning is a reinforcement learning framework for training maximum entropy policies in continuous domains. Includes the official implementation of the Soft Actor-Critic algorithm.

Overview

Softlearning

Softlearning is a deep reinforcement learning toolbox for training maximum entropy policies in continuous domains. The implementation is fairly thin and primarily optimized for our own development purposes. It utilizes the tf.keras modules for most of the model classes (e.g. policies and value functions). We use Ray for the experiment orchestration. Ray Tune and Autoscaler implement several neat features that enable us to seamlessly run the same experiment scripts that we use for local prototyping to launch large-scale experiments on any chosen cloud service (e.g. GCP or AWS), and intelligently parallelize and distribute training for effective resource allocation.

This implementation uses Tensorflow. For a PyTorch implementation of soft actor-critic, take a look at rlkit.

Getting Started

Prerequisites

The environment can be run either locally using conda or inside a docker container. For conda installation, you need to have Conda installed. For docker installation you will need to have Docker and Docker Compose installed. Also, most of our environments currently require a MuJoCo license.

Conda Installation

  1. Download and install MuJoCo 1.50 and 2.00 from the MuJoCo website. We assume that the MuJoCo files are extracted to the default location (~/.mujoco/mjpro150 and ~/.mujoco/mujoco200_{platform}). Unfortunately, gym and dm_control expect different paths for MuJoCo 2.00 installation, which is why you will need to have it installed both in ~/.mujoco/mujoco200_{platform} and ~/.mujoco/mujoco200. The easiest way is to create a symlink from ~/.mujoco/mujoco200_{plaftorm} -> ~/.mujoco/mujoco200 with: ln -s ~/.mujoco/mujoco200_{platform} ~/.mujoco/mujoco200.

  2. Copy your MuJoCo license key (mjkey.txt) to ~/.mujoco/mjkey.txt:

  3. Clone softlearning

git clone https://github.com/rail-berkeley/softlearning.git ${SOFTLEARNING_PATH}
  1. Create and activate conda environment, install softlearning to enable command line interface.
cd ${SOFTLEARNING_PATH}
conda env create -f environment.yml
conda activate softlearning
pip install -e ${SOFTLEARNING_PATH}

The environment should be ready to run. See examples section for examples of how to train and simulate the agents.

Finally, to deactivate and remove the conda environment:

conda deactivate
conda remove --name softlearning --all

Docker Installation

docker-compose

To build the image and run the container:

export MJKEY="$(cat ~/.mujoco/mjkey.txt)" \
    && docker-compose \
        -f ./docker/docker-compose.dev.cpu.yml \
        up \
        -d \
        --force-recreate

You can access the container with the typical Docker exec-command, i.e.

docker exec -it softlearning bash

See examples section for examples of how to train and simulate the agents.

Finally, to clean up the docker setup:

docker-compose \
    -f ./docker/docker-compose.dev.cpu.yml \
    down \
    --rmi all \
    --volumes

Examples

Training and simulating an agent

  1. To train the agent
softlearning run_example_local examples.development \
    --algorithm SAC \
    --universe gym \
    --domain HalfCheetah \
    --task v3 \
    --exp-name my-sac-experiment-1 \
    --checkpoint-frequency 1000  # Save the checkpoint to resume training later
  1. To simulate the resulting policy: First, find the absolute path that the checkpoint is saved to. By default (i.e. without specifying the log-dir argument to the previous script), the data is saved under ~/ray_results/<universe>/<domain>/<task>/<datatimestamp>-<exp-name>/<trial-id>/<checkpoint-id>. For example: ~/ray_results/gym/HalfCheetah/v3/2018-12-12T16-48-37-my-sac-experiment-1-0/mujoco-runner_0_seed=7585_2018-12-12_16-48-37xuadh9vd/checkpoint_1000/. The next command assumes that this path is found from ${SAC_CHECKPOINT_DIR} environment variable.
python -m examples.development.simulate_policy \
    ${SAC_CHECKPOINT_DIR} \
    --max-path-length 1000 \
    --num-rollouts 1 \
    --render-kwargs '{"mode": "human"}'

examples.development.main contains several different environments and there are more example scripts available in the /examples folder. For more information about the agents and configurations, run the scripts with --help flag: python ./examples/development/main.py --help

optional arguments:
  -h, --help            show this help message and exit

                        variant['run_params']['checkpoint_replay_pool']. Note
                        that the replay pool is saved (and constructed) piece
                        by piece so that each experience is saved only once.

Resume training from a saved checkpoint

This feature is currently broken!

In order to resume training from previous checkpoint, run the original example main-script, with an additional --restore flag. For example, the previous example can be resumed as follows:

softlearning run_example_local examples.development \
    --algorithm SAC \
    --universe gym \
    --domain HalfCheetah \
    --task v3 \
    --exp-name my-sac-experiment-1 \
    --checkpoint-frequency 1000 \
    --restore ${SAC_CHECKPOINT_PATH}
