Description

为Bert/GPT 模型批量添加更多的AutoConverter单测。

由于 t5 最核心的模型是 T5Model 和 T5ForConditionalGeneration，不适合批量添加更多下游模型，故在此不针对于 t5 系列模型做更多的调整。

there is an ci error in isort package, it seems that it's kown issue: pre-commit fails to install isort 5.11.4 with error "RuntimeError: The Poetry configuration is invalid".

So, I will try to upgrade the version of isort to 5.12.0.
