I couldn’t reproduce the error you having with microsoft/deberta-v3-small (because the large version doesn’t fit in google colab).
Can you confirm that it is the same problem as this issue 1?
If so, do you know how long ago you cloned the transformers library for your test? There have been changes 1 to the file transformers/models/deberta_v2/modeling_deberta_v2.py" 17 days ago that might have solved your problem.
