Failed to process: (InvalidArgument) Axis should be less than 1, but received axis is 1 [Hint: Expected axis < max_dim, but received axis:1 >= max_dim:1.] [operator < elementwise_floordiv > error]

我自己训练了一个ser模型，使用predict_kie_token_ser.py结果好好的，但是转成serving部署后就出现Axis should be less than 1这种情况。

经检查配置没有问题，之前训练的模型也能成功部署。我尝试过重新转推理模型再转serving，所有的配置项都一致。

目前的环境：
paddle-serving-app 0.9.0
paddle-serving-client 0.9.0
paddle-serving-server 0.9.0
paddlenlp 2.5.2
paddleocr 2.6
paddlepaddle 2.5.2

检查后发现，paddle_serving_server.pipeline.operator.py的predict这里报错，但是feed_batch的长度都是对的上的
