Most information about DatasetViewer is available on the DatasetViewer GitHub page, but here are some additional restrictions. There are certain limitations on size and file formats. > [@Generating Croissant Metadata for Custom Image Dataset](https://discuss.huggingface.co/t/generating-croissant-metadata-for-custom-image-dataset/150255): > > Dear Hugging Face Team, I am currently hosting a 3D reconstruction image dataset on the Hugging Face Hub: [yinyue27/RefRef · Datasets at Hugging Face](https://huggingface.co/datasets/yinyue27/RefRef). The dataset is in Blender format and contains multiple subsets, where each subset corresponds to a scene. Each scene is further divided into three splits: train, validation, and test. Each scene includes three JSON files that store the image paths for each split. Since Hugging Face could not automatically recognise the dataset’s structure, I impl… > [@Datasets viewer preview only](https://discuss.huggingface.co/t/datasets-viewer-preview-only/152080): > > Hi, I have been using the DataViewer to analyze my model’s output, which is pretty convenient and straightforward. But recently, due to the dataset keeping getting bigger and bigger, for some subset, the dataviewer can only show a preview of the data, which I found explained [here](https://huggingface.co/docs/hub/en/datasets-viewer#dataset-preview) Does it mean I have to manually delete some of that data to unlock the full data viewer again? It’s reasonable to set that limit, but I wonder if there is a way that we can flexibly configure which subset to be in t… --- _[View the full topic](https://discuss.huggingface.co/t/help-making-object-detection-dataset/152344)._
