问题 We are transitioning an existing Java production code to use Tensorflow Serving (TFS) for inferencing. We have already retrained our models and saved them using the new SavedModel format (no more frozen graphs!!). From the documentation that I have read, TFS does not directly support Java. However it does provide a gRPC interface, and that does provide a Java interface. My question, what are the steps involved in bringing up a Java application to use TFS. [Edit: moved steps to a solution] 回答1

问题 I am working on gRPC client(JavaFX) and server(SpringBoot with gRPC starter). The two application are independent and do not share any files together. The server is complete for testing(here) I would like to make JavaFX client independently from the gRPC server, i.e without including gRPC server as a maven dependancy in client POM. What gRPC client specific dependencies can i add in the javafx application and how to send request to the server? 回答1: According to the official documentation

问题 I am trying to run a java application using jar on raspberry pi modal 3. I am unable to resolve this issue. Could someone kindly suggest how can I make this work on the raspberry pi? In pom, I have included google-cloud-speech dependency, 0.56.0-beta; and spring-boot-starter-web dependency.

问题 I successfully created EmbeddedAssistantStub using the below code. EmbeddedAssistantGrpc.EmbeddedAssistantStub mAssistantService = EmbeddedAssistantGrpc.newStub(channel) .withCallCredentials(MoreCallCredentials.from( Credentials.fromResource(mClientId,mRefreshToken,mAccessToken) )); After this i passed audio data to StreamObserver, At that time below exxception was occured.

问题 I have deployed a web-application inside a tomcat container and have used grpc-netty (1.2.0) with netty-tcnative-boringssl-static:jar:1.1.33.Fork26. When i switch on debug logs it tells that "java.lang.IllegalArgumentException: Failed to load any of the given libraries: [netty-tcnative-linux-x86_64, netty-tcnative-linux-x86_64-fedora, netty-tcnative]" and then a error message "java.lang.IllegalArgumentException: Jetty ALPN/NPN has not been properly configured.". I have gone through the

问题 I have two servers - HelloServer and WorldServer. Both implement the same proto file: // The greeting service definition. service GreeterService { // Sends a greeting rpc GreetWithHelloOrWorld (GreeterRequest) returns (GreeterReply) {} rpc GreetWithHelloWorld (GreeterRequest) returns (GreeterReply) {} } message GreeterRequest { string id = 1; } // The response message containing the greetings message GreeterReply { string message = 1; string id = 2; } I want to add traceIds to the requests.

问题 I have a server written in Java and client written in PHP. How can client catch exception from server if anything goes wrong? I can't find anything about exception handling in gRPC documentation. Thank you! 回答1: For handled exceptions, call responseObserver.onError() . If you pass in a StatusRuntimeException or StatusException (generally created via status.asRuntimeException() ) the status code and description will be communicated to the client. Unhandled exceptions within a callback will

问题 I tried profiling a gRPC java server. And i see the below set of thread pools majorly. grpc-default-executor Threads : Created 1 for each incoming request. grpc-default-worker-ELG Threads: May be to listen on the incoming gRPC requests & assign to the above "grpc-default-executor" thread. Overall, is gRPC java server, Netty style or Jetty/Tomcat style? Or it can configured to run as both ways? 回答1: gRPC Java server is exposed closer to Jetty/Tomcat style, except that it is asynchronous. That

问题 I am sending data to grpc service and getting error message in return: Encountered end-of-stream mid-frame What does this mean. the connection was interrupted or something else like not enough data sent across. Was it a failure of my client to send enough data of the message over or was it some connection break in the middle of processing. I dont have enough information from this. If you dont know whats wrong here just tell me if it means the connection closed too early during processing or

问题 In this tutorial and example code, a server can call onNext() method on every stream observer, which will broadcast messages to all clients bi-streaming with the server. But there is no method to identify which observer corresponds to which client. How can a server push a message to specific client instead of broadcasting? According to this answer it is possible to map each observer if client id is provided by metadata. It seems const auto clientMetadata = context->client_metadata(); part
