[News!] We have tested the environment in Python 3.10 and PyTorch 2.0 with other packages in new versions. You can install the new environment from requirement2.yaml. Notice that new versions of gym and gymnasium are not consistent yet.
ILSwiss is an Easy-to-run Imitation Learning (IL, or Learning from Demonstration, LfD) framework (template) in PyTorch based on existing code base.
If you want to run image-based dm_control benchmark more efficiently, try this repo.
This repository is built on top of rlswiss and rlkit. The original rlswiss contains meta-rl methods and redundant codes, in this repo, we clean and optimize the code architecture, modify and re-implement algorithms for the purpose of easier running imitation learning experiments (rlkit focus on general RL algorithms). We further introduce vec envs to sample data in a parallel style to boost the sampling stage refering to tianshou and add tensorboard support. ILSwiss supports experiments logging using wandb, and envpool for accelerating training (see example yaml file in https://github.com/Ericonaldo/ILSwiss/blob/main/exp_specs/sac/sac_hopper_envpool.yaml).
You can easily build experiment codes under this framework in your research. We will continue to maintain this repo while keeping it clear and clean.

To make sure the code runs correctly, we recommend using the following environment:
- Linux platform (e.g. Ubuntu 18.04)
- Python 3.8 (Anaconda)
To install the required packages, run the following command:
pip install -r requirements.txt
Due to mysterious reasons (e.g. network issues), you may fail to install some packages. As an alternative, we recommend the following steps:
Install dmc2gym by running
pip install git+https://github.com/denisyarats/dmc2gym.git
Install PyTorch. Select an appropriate version to match your CUDA version, e.g.
pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu113
Install other packages by running
pip install -r requirements.txt
Before running, assign important log and output paths in rlkit/launchers/config.py.
There are simple multiple processing shcheduling (we use multiple processing to clarify it with multi-processing since it only starts many independent sub-process without communication) for simple hyperparameter grid search.
The main entry is run_experiment.py, with the assigned experiment yaml file in exp_specs/:
python run_experiment.py -g 0 -e your_yaml_path or python run_experiment.py -e your_yaml_path.
When you run the run_experiment.py, it reads the yaml file, and generate small yaml files with only one hyperparameter setting for each. In a yaml file, a script file path is assigned (see run_scripts/), which is specified to run the script with every the small yaml file. See exp_specs/sac/bc.yaml for necessary explaination of each parameter.
NOTE: all experiments, including the evaluation tasks (see run_scripts/evaluate_policy.py and exp_specs/evaluate_policy) and the render tasks, can be run under this framework by specifying the yaml file (in a multiple processes style).
RL algorithms do not need demonstrations. Therefore, all you need is to write an experiment yaml file (see an example in exp_specs/sac/sac_hopper.yaml) and run with the above suggestions.
For on-policy algorithms (e.g., PPO), we clean the buffer after every training step.
-e means the path to the yaml file, -g means gpu id.
run mbpo for hopper:
python run_experiment.py -e exp_specs/mbpo/mbpo_hopper.yaml -g 0
run sac-ae for finger_spin:
python run_experiment.py -e exp_specs/sac/sac_ae_dmc_finger_spin.yaml -g 0
run sac for hopper:
python run_experiment.py -e exp_specs/sac/sac_hopper.yaml -g 0
run ppo for hopper:
python run_experiment.py -e exp_specs/ppo/ppo_hopper.yaml -g 0
run td3 for humanoid:
python run_experiment.py -e exp_specs/td3/td3_humanoid.yaml -g 0
run her for pick with td3:
python run_experiment.py -e exp_specs/her/her_pick_td3.yaml -g 0
IL algorithms need to be assigned with demonstrations. The input-format-matching standard mujoco and dmc expert demonstrations data files run by us can be download in here. If you want to sample your own data, train an expert agent using RL algorithms and sample using run_scripts/gen_expert_demo.py or run_scripts/evaluate_policy.py, and do not forget to modify your IO format.
If you get the demos ready, write the path for each expert name in demos_listing.yaml (there are already some examples). Then you should specify the expert name and the traj number in the corresponding yaml file (see exp_specs/bc.yaml for example). After all the stuff, you can run it as a regular experiment following the above suggestions.
gen expert data for hopper:
python run_experiment.py -e exp_specs/gen_expert/hopper.yaml -g 0
run bc for hopper:
python run_experiment.py -e exp_specs/bc.yaml -g 0
run gail for walker:
python run_experiment.py -e exp_specs/gail/gail_walker.yaml -g 0
The project name in wandb can be configured in rlkit/launchers/config.py. And the experiment name for each trial shown in wandb UI is the same as exp_name in the yaml file.
See exp_specs for detailed curve results.
