问题 I'm trying to send an EventInput using python dialogflow client v2 (https://dialogflow.com/docs/reference/api-v2/rest/v2beta1/projects.agent.sessions/detectIntent#eventinput) but couldn't set parameters. Setting it to an object like {"result_guid": "49A8608C-4854-4964-81C3-0A75F912B994"} returns an error ValueError: Protocol message Struct has no "result_guid" field. How can this be solved? 回答1: found the solution. parameters needs to be a google.protobuf.Struct so something like below works

问题 I'm working on a project in which I need to analyze an image using Google's Vision API and post the response to a Dynamodb table. I have successfully implemented the Vision API, but not able to convert its response into Python Dictionary. Here's what I have tried: if form.is_valid(): obj = form obj.imageFile = form.cleaned_data['imageFile'] obj.textFile = form.cleaned_data['textFile'] obj.save() print(obj.imageFile) # Process the image using Google's vision API image_path = os.path.join

问题 I did everything it says at https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md and lastly updated my protoc. When i enter $ protoc --version , it throws libprotoc 3.5.1 on the terminal. But when i try to do $ python object_detection/builders/model_builder_test.py , it throws an error TypeError: _ new _() got an unexpected keyword argument 'serialized_options'. What am i doing wrong? 回答1: Based on this thread in the TensorFlow repository, you

问题 protogen.exe generates this pattern for a proto2 message field of type long : private long _Count = default(long); [global::ProtoBuf.ProtoMember(1, IsRequired = false, Name=@"Count", DataFormat = global::ProtoBuf.DataFormat.TwosComplement)] [global::System.ComponentModel.DefaultValue(default(long))] public long Count { get { return _Count; } set { _Count = value; } } but as proto2 does not include a date-time type ( and protobuf-net does not support proto3 which includes google.protobuf

问题 I have a python list of integers, and I'd like to know how much space it will take up when encoded as a sequence of Protocol Buffers variable-length integers, or varints. What's the best way to figure this out without actually encoding the integers? my_numbers = [20, 69, 500, 38987982344444, 420, 99, 1, 999] e = MyCoolVarintArrayEncoder(my_numbers) print(len(e)) # ??? 回答1: Each integer is encoded in base 128, one byte per "digit". The length of an integer value's representation in any base is

问题 I am having trouble importing Protobuf generated classes using Gradle. This is how my project tree looks like: I've tried marking the packages as Source, I have tried all possible combinations of imports: import generated.main.grpc.GreeterGrpc; import main.java.HelloRequest; import java.*; import HelloRequest; None of them works. Here is my build.gradle: group 'andu' version '1.0-SNAPSHOT' apply plugin: 'java' apply plugin: 'com.google.protobuf' sourceCompatibility = 1.5 repositories {

问题 Since I am not getting an answer on this question I gotta prototype and check myself, as my dataset headers need to be fixed size, I need fixed size strings. So, is it possible to specify fixed size strings or byte arrays in protocol buffers ? It is not readily apparent here, and I kinda feel bad about forcing fixed size strings into the header message. --i.e, std::string('\0', 128) ; If not I'd rather use a #pragma pack(1) struct header {...}; ' edit Question indirectly answered here. Will

问题 I have studied the existing examples: Sending Protobuf Messages with boost::asio Reading Protobuf objects using boost::asio::read_async Google Protocol Buffers: parseDelimitedFrom and writeDelimitedTo for C++ Are there C++ equivalents for the Protocol Buffers delimited I/O functions in Java? Sending Protobuf Messages with boost::asio but I still can not figure out how to pass Google Protobuf messages using the Boost::asio API. In particular I have no clear understanding of the following

问题 i'm new to protocol buffers and I am using protobuf-net for VS2010. from what i'm reading here Dictionary in protocol buffers, it doesn't seem that protobuf can serialize a dictionary with object types as values. but here on his site i read this: Notes on types supported: custom classes that: are marked as data-contract have a parameterless constructor for Silverlight: are public many common primitives etc single dimension arrays: T[] List / IList Dictionary / IDictionary any type which

问题 I've been trying since the morning but I didnt achieve what I wanted. I tried DispatchQueue.main.async and completion block but my "Submit" button in the UI still freezes waiting for the data to be returned from the server. This is my code: func createData(request:Crudpb_CreateRequest, with completion: @escaping (String) -> Void) throws { DispatchQueue.main.async { self.response = try! self.client.create(request) // <---- How to handle error for this server call when the server is not
