EgoMimic: Scaling Imitation Learning through Egocentric Video

This repository contains the data processing and training code for EgoMimic - Both for Human Aria and Robot teleoperated Data. To rollout policies in the real world, you'll additionally need our hardware repo Eve.

Structure

• egomimic/scripts/aloha_process: Process raw aloha style data into a robomimic style hdf5, compatible for training here.
• egomimic/scripts/aria_process: Process human embodiment data from Aria Glasses into a robomimic style hdf5.
• egomimic/algo: Algorithm code for Egomimic, as well as ACT and mimicplay baselines
• egomimic/configs: Train configs for each algorithm
• egomimic/scripts/pl_train.py: Main training script, powered by Pytorch Lightning (DDP enabled)
• data_processing.md: Instructions to process your own data, both Aria Human data and teleoperated robot data.

Installation

git clone --recursive git@github.com:SimarKareer/EgoMimic.git
cd EgoMimic
conda env create -f environment.yaml
pip install projectaria-tools'[all]'
pip install -e external/robomimic
pip install -e .
python external/robomimic/robomimic/scripts/setup_macros.py

Set git config --global submodule.recurse true if you want git pull to automatically update the submodule as well.

Then go to external/robomimic/robomimic/macros_private.py and manually add your wandb username. Make sure you have ran wandb login too.

EgoMimic Quick Start (Train on Sample Data)

EgoMimic Training (Toy in Bowl Task)

python scripts/pl_train.py --config configs/egomimic_oboo.json --dataset /path/to/bowlplace_robot.hdf5 --dataset_2 /path/to/bowlplace_human.hdf5 --debug

ACT Baseline Training

python scripts/pl_train.py --config configs/act.json --dataset /path/to/bowlplace_robot.hdf5 --debug

For a detailed list of commands to run each experiment see experiment_launch.md

Use --debug to check that the pipeline works

Launching runs via submitit / slurm

python scripts/pl_submit.py --config <config> --name <name> --description <description> --gpus-per-node <gpus-per-node>`

Training creates a folder for each experiment

./trained_models_highlevel/description/name
├── videos (generated offline validation videos)
├── logs (wandb logs)
├── slurm (slurm logs if launched via slurm)
├── config.json (copy of config used to launch this run)
├── models (model ckpts)
├── ds1_norm_stats.pkl (robot dataset normalization stats)
└── ds2_norm_stats.pkl (hand data norm stats if training egomimic)

Offline Eval: python scripts/pl_train.py --dataset <dataset> --ckpt_path <ckpt> --eval

Processing your own data for training

See data_processing.md

Rollout policies in the real world

Follow these instructions on the desktop connected to the real hardware.

1. Follow instructions in Eve
2. Install the hardware package into the emimic conda env via

conda activate emimic
cd ~/interbotix_ws/src/eve
pip install -e .

3. Rollout policy

cd EgoMimic/egomimic
python scripts/evaluation/eval_real --eval-path <path to>EgoPlay/trained_models_highlevel/<your model folder>/models/<your ckpt>.ckpt
