Why Does My Dataset Collection Process Fail with Errors on Initialization?
-
Experts, I encountered an error when starting the dataset collection process. What could be the cause?
python lerobot/scripts/control_robot.py \
--robot.type=so100 \
--control.type=record \
--control.fps=30 \
--control.single_task="Grasp a lego block and put it in the bin." \

--control.tags='["so100","tutorial"]' \
--control.warmup_time_s=5 \
--control.episode_time_s=30 \
--control.reset_time_s=30 \
--control.num_episodes=2 \
--control.push_to_hub=false
