Language Table

Language-Table is a suite of human-collected datasets and a multi-task continuous control benchmark for open vocabulary visuolinguomotor learning.

Installation

Installation with pip. requirements.txt contains dependencies for running the environment and simple dataset examples.

python3 -m venv ./ltvenv
source ./ltvenv/bin/activate
pip install -r ./requirements.txt
export PYTHONPATH=${PWD}:$PYTHONPATH

For running the full train script, install using requirements_static.txt, as this contains pinned versions for running the full train script.

python3 -m venv ./ltvenvtrain
source ./ltvenvtrain/bin/activate
pip install --no-deps -r ./requirements_static.txt
export PYTHONPATH=${PWD}:$PYTHONPATH

Quickstart

Examples

Scripts

Run and edit the following examples:

Load the environment and run 5 random steps:

python3 language_table/examples/environment_example.py

Load dataset and print first 5 elements:

python3 language_table/examples/dataset_example.py

Train

source ./ltvenvtrain/bin/activate
mkdir -p /tmp/language_table_train/
PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python  python language_table/train/main.py --config=./language_table/train/configs/language_table_sim_local.py --workdir=/tmp/language_table_train/

Abstract. We present a framework for building interactive, real-time, natural language-instructable robots in the real world, and we open source related assets (dataset, environment, benchmark, and policies). Trained with behavioral cloning on a dataset of hundreds of thousands of language-annotated trajectories, a produced policy can proficiently execute an order of magnitude more commands than previous works: specifically we estimate a 93.5% success rate on a set of 87,000 unique natural language strings specifying raw end-to-end visuolinguo-motor skills in the real world. We find that the same policy is capable of being guided by a human via real-time language to address a wide range of precise long-horizon rearrangement goals, e.g. "make a smiley face out of blocks". The dataset we release comprises nearly 600,000 language-labeled trajectories, an order of magnitude larger than prior available datasets. We hope the demonstrated results and associated assets enable further advancement of helpful, capable, natural-language-interactable robots.
