描述问题/Describe the bug

当我在使用pp yoloe这个模型训练时导出的模型在使用deploy预测时会报错显示No object detected，在查看源码后得知，其infer支持的模型不包括上述模型，但是在官方示例中所给出的导出模型以及推理的方案都是如此，在遵循官方示例操作后仍然有问题，所以希望能够得到准确的答复，谢谢各位大佬

复现/Reproduction

请填写命令/A placeholder for the command.

2. 您是否更改过代码或配置文件？您是否理解您所更改的内容？还请您提供所更改的部分代码。/Did you make any modifications on the code or config? Did you understand what you have modified? Please provide the codes that you modified.
