已完全按照 https://github.com/PaddlePaddle/FastDeploy/blob/develop/examples/vision/detection/paddledetection/serving/README_CN.md 文档部署

使用Gradio执行报

Error: [400] in ensemble 'ppdet', Failed to process the request(s) for model instance 'preprocess_0', message: Stub process is not healthy.�

在终端使用paddledet_grpc_client.py执行报

Start with examples/vision/detection/paddledetection/serving/README_CN.md and paddledet_grpc_client.py, then reproduce the request through Gradio or the gRPC client while checking the VisualDL logs. Trace why preprocess_0 receives an array with the wrong rank and verify that the serving example completes inference without the Stub process becoming unhealthy.
