Hi ! the viewer on the dataset page seems to be working now :)

This error is showing up when paginating though:

Parquet error: Scan size limit exceeded: attempted to read 455432084 bytes, limit is 300000000 bytes Make sure that 1. the Parquet files contain a page index to enable random access without loading entire row groups2. otherwise use smaller row-group sizes when serializing the Parquet files

This can be caused by old versions of datasets that upload Parquet files with too big row groups.
You can fix the issue by reuploading with a more recent version of datasetsand push_to_hub()
