错误描述

我在训练transformer的时候遇到bug，报错代码中说多传了output_attention，在paddlenlp/transformers/model_outputs.py中，我将output_attentions=output_attentions注释掉后错误就消失了，哪位大佬能告诉我原因，感谢！！ (之前ppnlp 2.1.1没有该错误)

稳定复现步骤 & 代码

模型在 ppseq/models/transformer/transformer_model.py 下
git clone https://gitee.com/miugod/PaddleSeq.git
cd PaddleSeq
git checkout develop
pip install -r requirements.txt && pip install -e .

数据集：https://aistudio.baidu.com/aistudio/datasetdetail/203506

unzip datasets.zip
ppseq_train -c examples/iwslt14/configs/de_en.yaml

错误版本：
pip install paddlenlp --upgrade
sed -i "s/paddlenlp==2.1.1/paddlenlp>=2.1.1/g" setup.py
pip install -e .
ppseq_train -c examples/iwslt14/configs/de_en.yaml

可以验证下，升级到最新paddleNLP版本是否还有这个问题？

您好，已经升级到最新版本了，这导致了报错（原先2.1.1不会）：

我也遇到了类似的问题，我使用gpt2和opt都遇到了forward方法没有labels这个参数的问题
