  "textContent": "Hi @lhoestq\n\nThanks for your reply!\n\nThe repository is:\n\nhuggingface.co\n\n### amir-kazemi/aidovecl-vehicle-detection-classification-localization · Datasets...\n\nWe’re on a journey to advance and democratize artificial intelligence through open source and open science.\n\n> Please note that my Parquet files do not contain image bytes; they only store relative image paths.\n\nSo far, I have tried the following:\n\n  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:\n\n\n\n\n    configs:\n      - config_name: default\n        data_files:\n          - split: train\n            path: train/metadata.parquet\n          - split: validation\n            path: val/metadata.parquet\n          - split: test\n            path: test/metadata.parquet\n\n\n  2. 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.\n\n\n\nPlease let me know if you need more information.",
