Transformers解决RuntimeError: element 0 of tensors does not require grad and does not have a grad_fn

在使用Transformers启动梯度检查点时，即：

model.gradient_checkpointing_enable()

时，会报错RuntimeError: element 0 of tensors does not require grad and does not have a grad_fn。

解决办法：在get_peft_model之前加上：

model.enable_input_require_grads()
