Question about the number of episodes

#1

Hi, thank you very much for open-sourcing the LeRobot-format Droid dataset. I notice that the number of episodes is 62746, which is different from that of the original Droid RLDS version (92233). I wonder what's the difference? Look forward to your reply.

Hi, sorry for the inconvenience. The current dataset is still being uploaded and due to Hugging Face's rate limiting issue, I'm unable to upload all files at once. Please try downloading the complete dataset at least 2 days from now.

The number of episodes in the complete dataset is 92233.

Thanks for your reply. I have another question: RLDS has compressed the images with JPEG, and LeRobot saves the camera data with MP4, which compresses the frames again. Will it affect the image quality?

Thank you for your attention to details. Indeed, encoding the image twice may affect the original data, but this impact should be negligible. I’ve calculated the difference between the images after two encodings, and I found that the discrepancy is always within 10, which is similar to a random enhancement effect. Therefore, I believe the impact is minimal.

Additionally, you can visit our visualizer to view the converted video online. The difference between the converted video and the original one should be imperceptible to the naked eye.

Cool. Thank you again for the nice work!

Hi, sorry to bother you again. I find there is no videos/ folder. Is the uploading still running?
