SmolVLA HF Documentation

Designed by Hugging Face.

This model has 450M parameters in total. You can use inside the LeRobot library.

Before proceeding to the next steps, you need to properly install the environment by following Installation Guide on the docs.

Install smolvla extra dependencies:

pip install -e ".[smolvla]"

Example of finetuning the smolvla pretrained model (smolvla_base):

python lerobot/scripts/train.py \
  --policy.path=lerobot/smolvla_base \
  --dataset.repo_id=lerobot/svla_so101_pickplace \
  --batch_size=64 \
  --steps=20000 \
  --output_dir=outputs/train/my_smolvla \
  --job_name=my_smolvla_training \
  --policy.device=cuda \
  --wandb.enable=true

Example of finetuning the smolvla neural network with pretrained VLM and action expert intialized from scratch:

python lerobot/scripts/train.py \
  --dataset.repo_id=lerobot/svla_so101_pickplace \
  --batch_size=64 \
  --steps=200000 \
  --output_dir=outputs/train/my_smolvla \
  --job_name=my_smolvla_training \
  --policy.device=cuda \
  --wandb.enable=true
