Hyperparameter tuning

Hello, I’m a new user of ray tune. I want to tune the hyperparameters of pretrained tensorflow model from huggingface but i 'm facing some problems with my code which i just follow the documentation can you please tell me what is wrong with it

or you can give me an example with ray tune and tesnorflow transformer model from huggingface for summarization task. thanks

Looks like the same as Tuning TF pretrained models hyperparameters. Will be answering there. Could you resolve this post?
