PyRoboFrames
Dataloader for robotics video. Support for LeRobot format 3
High-performance ML dataloader for robotics. LeRobot format, hardware-accelerated video decode Try - pip install pyroboframes
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

Who hunted PyRoboFrames?
PyRoboFrames was hunted by Georgi Mullassery. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
