Why is `token-classification` with T5 not available? (`T5ForTokenClassification`)

[debevv]

Question

In python tranformers i can do:

model = AutoModelForTokenClassification.from_pretrained("google-t5/t5-base")

and use it with Trainer to train it (quite successfully).
Or

classifier = pipeline("token-classification", model="google-t5/t5-base")

and use it for token classification.

Instead, if I try to use it in transformers.js (web, 3.7.3):

classifier = await pipeline('token-classification', "google-t5/t5-base")

I receive this error:

Unsupported model type: t5

How come? Or there is another way to use T5 for token classification in javascript?
