Data Corruption Issue Found in MobileViews Dataset
Hello,
I have downloaded the MobileViews dataset, specifically the files MobileViews_0-291197.tar.gz and MobileViews_300000-522301.tar.gz. After attempting to extract these files using gzip on both Windows and Linux, I encountered data corruption errors. Both files seem to be damaged, as they failed the integrity check with the gzip -t command. It’s also possible that I am not extracting them correctly.
Could you please verify the integrity of these dataset files or provide new, error-free versions? I would greatly appreciate your assistance in resolving this issue.
Hello,
The issue you're encountering may be due to not using Git LFS to correctly download the large files in the dataset.
Please follow the instructions in the How to Use section of the README to ensure that the files are properly downloaded and extracted.
If you continue to have trouble, feel free to reach out, and we can investigate further.
@GaoLongxi Hi,
Thank you for providing such a fantastic resource! However, I did encounter some issues with the data, too. I followed the instructions in the README precisely, but it seems there is a problem with data corruption, which is preventing me from accessing the full dataset. The screenshot of the error message is shown below.
Could you please assist with resolving this issue?
Thank you!

Hi,
Thank you for your kind feedback and for bringing this issue to my attention. I apologize for the delayed response.
From the error message you shared, it appears that the data corruption might have occurred during the download process. This could be due to an incomplete download of the .tar.gz files when using git lfs pull.
To help troubleshoot and resolve this issue, please follow these steps:
- Check the file sizes.
du -sh /path/to/your/downloaded/file
Compare the local file sizes to the ones shown on the repository's webpage, as the expected sizes are as follows:
MobileViews_0-291197.tar.gz: 11.9 GB
MobileViews_300000-522301.tar.gz: 11 GB
- Retry the download. If the file sizes do not match, please try running git lfs pull again to ensure the files are fully downloaded. You may want to check for any interruptions in your internet connection during the download.
If you continue to experience issues, feel free to reach out, and I will assist you in resolving the problem. Thank you for your patience, and I appreciate your understanding.

Hi, @AkimotoAyako and @StarWalkin :
We’ve uploaded new .zip and .parquet versions of the MobileViews dataset to fix the issues with "data corruption" and "missing samples" in the previous tar files.
If you ran into any problems with the old files, please try downloading the new versions. We’ve also updated the README with detailed instructions for using the new formats.
Thanks for your patience, and feel free to reach out if you have any questions!
