LeRobot on a Jetson: why there is no pip install torch, and what it took
pip install lerobot fails on a Jetson Orin with an error that says almost nothing. The cause: LeRobot needs Python ≥ 3.12 and torchcodec ≥ 0.11 on aarch64 with CUDA, and no channel (NVIDIA's redist, the community index) ships a cp312 CUDA torch wheel for Jetson. The fix is a Docker image that builds the stack from source; it is merged upstream as LeRobot #4599 and published on GHCR. This post is about the traps underneath it.
