Dataset viewer broke after repo rename

Hi @lhoestq

Thanks for your reply!

The repository is:

huggingface.co

amir-kazemi/aidovecl-vehicle-detection-classification-localization · Datasets...

We’re on a journey to advance and democratize artificial intelligence through open source and open science.

Please note that my Parquet files do not contain image bytes; they only store relative image paths.

So far, I have tried the following:

  1. I added the following to the configs section of README.md. In this case, no error appears, but image thumbnails are no longer shown as they were before the rename, and the viewer shows only the relative paths instead:
configs:
  - config_name: default
    data_files:
      - split: train
        path: train/metadata.parquet
      - split: validation
        path: val/metadata.parquet
      - split: test
        path: test/metadata.parquet
  1. I also tried JSONL files, which are now in the repository root. In those files, the file_name column contains fully resolved URLs such as https://huggingface.co/datasets/amir-kazemi/aidovecl-vehicle-detection-classification-localization/resolve/main/test/images/<image_name> rather than relative paths. In that case, the previewer never fully loaded into the full viewer. A few initial rows were displayed successfully, but then the viewer showed an error, which I believe was related to PyArrow and masks. For the JSONL files, I also tried to align the objects field more closely with standard computer vision formats, but I suspect the error may come from the viewer interpreting my annotations as masks, even though they are only bounding boxes.

Please let me know if you need more information.
