https://huggingface.co/datasets/glue includes:

• datasets where we may have several input columns ( https://huggingface.co/datasets/glue/viewer/mnli/train , https://huggingface.co/datasets/paws )
• datasets where the labels are floats on a given range, task is regression ( https://huggingface.co/datasets/glue/viewer/stsb/train )

It would be nice to support those in TextClassificationEvaluator.
