Dataset Viewer issue: FileFormatMismatchBetweenSplitsError when using webdataset
The dataset viewer is not working.
Error details:
Error code: FileFormatMismatchBetweenSplitsError
All three splits, train, test, and validation, use webdataset. But only the train split has more than one file. How can I force the other two splits to also be interpreted as being the webdataset format?

Hi ! sorry for the delay, it seems your dataset contains JSON files that can't be loaded in Arrow (which is required to make the viewer work). This can happen when some fields in your JSON data have varying types (e.g. have a mix of string or int in a list). There is some work on the Arrow and HF community side to support such data (using the JsonType in Arrow), but this feature is not available yet.
