protocol-buffers

问题 I would like to include a protocol definition file in another protocol file. For example: // base.proto: message P_EndPoint { required int32 id = 1; required string host = 2; required int32 port = 3; } Then in another file: communication.proto: // somehow include `base.proto' // ... message P_CommunicationProtocol { required CP_MessageType type = 1; optional int32 id = 2; optional P_EndPoint identity = 3; repeated P_EndPoint others = 4; } // ... (Note: developers.google.com is not available

问题 I am trying to run a very simple saving of a Tensorflow graph as .pb file, but I have this error when parsing it back: Traceback (most recent call last): File "test_import_stripped_bm.py", line 28, in <module> graph_def.ParseFromString(fileContent) File "/usr/local/lib/python3.5/dist-packages/google/protobuf/message.py", line 185, in ParseFromString self.MergeFromString(serialized) File "/usr/local/lib/python3.5/dist-packages/google/protobuf/internal/python_message.py", line 1069, in

问题 I am currently trying to use Tensorflow's shared library in a non-bazel project, so I creat a .so file from tensorflow using bazel. but when I launch a c++ program that uses both Opencv and Tensorflow, it makes me the following error : [libprotobuf FATAL external/protobuf/src/google/protobuf/stubs/common.cc:78] This program was compiled against version 2.6.1 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.1.0). Contact the program author for an

问题 Currently I have a RESTful web service with endpoints that are exposed via Jersey/JAX-RS: @Path("/widgets") public class WidgetResource { @GET List<Widget> getAllWidgets() { // gets Widgets somehow } @POST Widget save(Widget w) { // Save widget and return it } } I use Jackson for serializing/deserializing my POJOs into JSON, and my service both responds to and sends back my POJOs as application/json . I am now looking to possibly use Google protocol buffers (or an equivalent technology) to

问题 I'm implementing a client-server application, and am looking into various ways to serialize and transmit data. I began working with Xml Serializers, which worked rather well, but generate data slowly, and make large objects, especially when they need to be sent over the net. So I started looking into Protobuf, and protobuf-net. My problem lies in the fact that protobuf doesn't sent type information with it. With Xml Serializers, I was able to build a wrapper which would send and receive any

问题 I have the following code in a protocol buffer file(pcfg_lm.proto): import "../types/language.proto"; package nlp; message PCFGProto { required Language lang = 1; } And of course there is a proto file exists at ../types/language.proto. However, when I issue the command: protoc pcfg_lm.proto --cpp_out=/tmp Here is the error message: ../types/language.proto: File not found. pcfg_lm.proto: Import "../types/language.proto" was not found or had errors. pcfg_lm.proto:6:12: "Language" is not defined

问题 I would like to install the older version of Google Protocol Buffers (protobuf-2.4.1) on mac using Terminal command line. I tried with brew install protobuf , but the latest version 2.5.0 has been installed. Is it possible to install the older version from terminal. Thanks 回答1: There are some issues with building protobuf 2.4.1 from source on a Mac. There is a patch that also has to be applied. All this is contained within the homebrew protobuf241 formula, so I would advise using it. To
