使用FastDeploy搭建PP-OCRv3模型服务后怎么配置参数

系统环境/System Environment：docker
版本号/Version： fastdeploy:1.0.4-cpu-only-21.10

小白一个，目前服务部署起来了，但是我想配置一下文本框识别数量上限这种参数。小白凭个人猜测对着det_postprocess文件夹下的config.pbtxt文件改了两下会报错。求大神指点该怎么写，怎么配置……

尝试在config.pbtxt中直接加入max_candidates: 2

[libprotobuf ERROR /tmp/tritonbuild/tritonserver/build/_deps/repo-third-party-build/grpc-repo/src/grpc/third_party/protobuf/src/google/protobuf/text_format.cc:317] Error parsing text-format inference.ModelConfig: 46:27: Message type "inference.ModelConfig.ParametersEntry" has no field named "max_candidates".

尝试加入parameters {max_candidates: 2}

[libprotobuf ERROR /tmp/tritonbuild/tritonserver/build/_deps/repo-third-party-build/grpc-repo/src/grpc/third_party/protobuf/src/google/protobuf/text_format.cc:317] Error parsing text-format inference.ModelConfig: 46:27: Message type "inference.ModelConfig.ParametersEntry" has no field named "max_candidates".

Start with models/det_postprocess/config.pbtxt in the PP-OCR serving example and review how its Triton model configuration is structured. Reproduce the reported parsing error, then identify the supported configuration path for the requested text-box limit and document the valid setting and an example that lets the service start successfully.
