描述问题

准备将PP-DocLayoutV2 通过转换为ONNX，然后转换为OM模型在昇腾芯片上部署。但是发现第一步转ONNX的时候存在问题。

复现

Paddle2ONNX指导文档使用的是inference.json进行ONNX转换，这个命令对于PP-DocLayout_plus-L是可以运行成功的
paddle2onnx --model_dir=/root/.paddlex/official_models/PP-DocLayout-L --model_filename inference.json --params_filename inference.pdiparams --save_file=./PP-DocLayout-L/inference.onnx --enable_onnx_checker=True

但是由于PP-DocLayoutV2 没有提供inference.json文件，只有inference.pdmodel，执行以下命令会报错

paddle2onnx --model_dir=/root/.paddlex/official_models/PP-DocLayoutV2 --model_filename inference.pdmodel --params_filename inference.pdiparams --save_file=./PP-DocLayoutV2 /inference.onnx --enable_onnx_checker=True

其中有一段话[WARNING] The .pdmodel file is deprecated in paddlepaddle 3.0 and will be removed in the future. Try to convert from .pdmodel file to json file. 提示尽量使用json进行转换。
