训练mbart模型报错 ，Logits和Label维度不匹配

[Amy234543]

paddlepaddle-gpu 2.5.2.post112 paddlenlp 2.7.1

报错信息： ValueError: (InvalidArgument) Input(Logits) and Input(Label) should in same shape in dimensions except axis. [Hint: Expected logits_dims[i] == labels_dims[i], but received logits_dims[i]:288 != labels_dims[i]:256.] (at ../paddle/phi/infermeta/binary.cc:909) 请问下怎么解决

请问下，是使用自己的数据来训练的吗？
