high-level generation workflows (e.g. a LM class) on T5 (and Flan T5) is missing.

[debrupf2946]

In Keras NLP t5 model the architecture and weights are present, but HL workflows are missing

I would like to contribute a high-level masked language modeling workflow in the t5 model

This Idea is suggested by @fchollet in the Keras-user group

@mattdangerw can you please help me with setting up the project
**Environment:**Linux
I installed from contributing.MD (CPU only)

Got following message in Terminal

Successfully built keras-nlp-0.7.0.tar.gz and keras_nlp-0.7.0-py3-none-any.whl
Build successful. Wheel file available at /home/debrup/keras-nlp/dist/keras_nlp-0.7.0-py3-none-any.whl

Successfully installed keras-nlp-0.7.0

But in VS-Code when I am running a particular file I get this error

Can you please help me out,its my first contribution and I really want to make it

@mattdangerw @fchollet
I have made t5_preprocessor file which adds padding to the sentence packs(input id and padding) I have also tested works fine.
I am working on the t5_MaskedLMMask Generator I am having a problem here what should be the mask token Id
There is no mask-token-id in the t5 tokenizer file.
can you help me with some ideas how to handle the mask token in t5

Should I create a pull request for t5_preprocessor for review ,I am completed with it
