PyRoboFrames
Dataloader for robotics video. Support for LeRobot format 3
PyRoboFrames is a foundation library for robot learning intelligence — load any robot learning dataset with quality validation, accelerate video decode with hardware (VideoToolbox/NVDEC), track data provenance, and stream to NumPy/MLX/PyTorch/JAX.
Architectural Role: Owns robot learning data pipelines. Loads, validates, and optimizes training data with quality metadata and data composition tracking. Quality metadata flows downstream to training systems.
10× speedup without code changes — Hardware-accelerated video decode (VideoToolbox on macOS, NVDEC on NVIDIA)
Zero-copy data transfer — Stream directly to MLX, PyTorch, or JAX without intermediate copies
Quality validation built-in — Detect corrupted frames, missing episodes, and data drift before training
Multi-dataset composition — Mix LeRobot, HDF5, NetCDF, and cloud datasets in one training loop
