long-t5-local-large

like 4

The demo in the web page failse with error:

The model_type 'longt5' is not recognized. It could be a bleeding edge model, or incorrect

And the code:

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
model = AutoModelForSeq2SeqLM.from_pretrained("google/long-t5-local-base")

Fails with the error:
```
