T5-base fine-tune input length

[ZahraTaherikhonakdar]

Hello,

I've tried to fine-tune t5-base on google cloud tpu. with input length as follow:
--gin_param="utils.run.sequence_length = {'inputs': 2048, 'targets': 64}"\
but I faced following error. I also tried 'inputs': 1024 with but faced the same error. I would be appreciate it if someone help me with this error and answer my question:

• what was the input size of the t5-base model during training?
• is it possible to fine-tune t5 with input size more than 512?
  Thank you in advance
