So in the training colab at https://colab.research.google.com/github/huggingface/notebooks/blob/main/lerobot/training-act.ipynb
This is the corrected code, the training script broke, due to the lerobot github repository reorganizing itself
!cd lerobot && python lerobot/scripts/train.py \
--dataset.repo_id=${HF_USER}/il_gym0 \
--policy.type=act \
--output_dir=outputs/train/il_sim_test0 \
--job_name=il_sim_test \
--policy.device=cuda \
--wandb.enable=true
should instead be
!python lerobot/src/lerobot/scripts/train.py \
--dataset.repo_id=${HF_USER}/jenga_dataset_2_video \
--policy.type=act \
--output_dir=outputs/train/il_sim_test0 \
--job_name=il_sim_test \
--policy.device=cuda \
--policy.push_to_hub=false
