Worked on the huggingface/lerobot repository, focusing on improving the reliability of onboarding materials by addressing a targeted bug in the example_1 Python script. The work involved correcting a typo and updating the logic for loading state vectors, ensuring that the observation state shape accurately matched the loaded data. By refining the script’s comments and aligning the expected input shapes, the developer enhanced the accuracy of tutorials and demos, reducing the risk of misconfiguration for new users. This contribution leveraged scripting skills in Python and emphasized code correctness, prioritizing quality improvements over new feature development during the reported period.
