请提出你的问题

在使用 PaddleFormers 进行 SFT LoRA 微调时，训练过程在 evaluation 阶段报错：NameError: name 'GPTModel' is not defined

使用以下配置进行 LoRA SFT 训练：

model_name_or_path: baidu/ERNIE-4.5-0.3B-Base-PT
lora: true
lora_rank: 8
stage: SFT
fine_tuning: lora
do_train: true
do_eval: true
eval_steps: 100
evaluation_strategy: steps

Traceback (most recent call last):

or (isinstance(self.model, LoRAModel) and isinstance(self.model.model, GPTModel))
NameError: name 'GPTModel' is not defined
