LoHoRavens

This repository is based on the minibatch training enabled CLIPort repository CLIPort-Batchify. The video and homepage of this project are available at this website.

Warnings: I'm currently refactoring the code and write documentation for this repo. Feel free to provide feedback to me. Thanks for your patience to explore this code repo.

Installation (overriding the original repo)

  1. Create environment:
conda create -n lohoravens python=3.8
  1. Activate environment:
conda activate lohoravens
  1. Clone LoHoRavens
git clone https://github.com/Shengqiang-Zhang/lohoravens.git
  1. Install from requirements:
conda install pip
cd cliport-batchify
pip install -r requirements.txt
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
pip install pytorch-lightning==1.9.5
python setup.py develop

TODO: add config dependencies on LLM and VLM.


Generate dataset

python cliport/demo.py n=1000 \
    task=pick-and-place-primitive \
    mode=train

In addition, we provide the method to generate the step-by-step instructions and corresponding images, which could be used for fine-tuning LLaVA. To do this, just set Task.generate_instruction_for_each_step=True and the save paths for instructions and images in the file cliport/tasks/task.py.

Train the primitive

python cliport/train.py train.task=lohoravens-pick-and-place-primitive \
    train.agent=cliport \
    train.attn_stream_fusion_type=add \
    train.trans_stream_fusion_type=conv \
    train.lang_fusion_type=mult \
    train.lr="${TRAIN_LR}" \
    train.batch_size="${BATCH_SIZE}" \
    train.gpu="${GPU_SIZE}" \
    train.n_demos=1000 \
    train.n_steps=601000 \
    train.n_val=200 \
    dataset.cache=False \
    train.exp_folder=${EXP_FOLDER} \
    train.data_dir=${ONE_K_DATA_FOLDER} \
    dataset.type=multi \
    train.log=True  \

Evaluate the primitive

python cliport/eval.py model_task=lohoravens-pick-and-place-primitive \
    eval_task=lohoravens-pick-and-place-primitive \
    agent=cliport \
    mode=${mode} \
    n_demos=200 \
    train_demos=1000 \
    checkpoint_type=${CKPT} \
    type=multi \
    model_dir=${MODEL_DIR} \
    exp_folder=exps \
    data_dir=${DATA_DIR} \

Use LLM and VLM

python eval_llm_vlm.py
