Trip pit: WIN7 + VS2015 compiler Ali MNN framework

Used Tencent ncnn, compile them very friendly; but 3d operation operator support is not enough; cause the model to emerging unusable.

See mnn Ali developed to taste fresh, the result of intermittent toss two days, in order to remember it.

thank you very much:

Which details a number of configurations.

1. Set

2, the powershell ./schema/generate.ps1 into python ./schema/generate.py

If you want to compile x64, will

os.system('cmake -DCMAKE_BUILD_TYPE=Release ..')

changed to

os.system('cmake -G "Visual Studio 14 2015 Win64" -DCMAKE_BUILD_TYPE=Release ..')

This step can also go directly to the

https://github.com/google/flatbuffers/releases

下flatc.exe，在..\MNN-master\3rd_party\flatbuffers\tmp\flatc.exe

3、cmake x64 only mnn.lib/mnn.dll

mkdir vs15x64 && cd vs15x64 
cmake  -G "Visual Studio 14 2015 Win64" -DCMAKE_BUILD_TYPE=Release ..
cd..
cmake --build vs15x64 --config Release

There will be normal

error C2280: 'std::unique_ptr<MNN::Pipeline,std::default_delete<_Ty>> &std::unique_ptr<_Ty,std::default_delete<_Ty>>::operator =(const std::unique_ptr<_Ty,std::default_delete<_Ty>> &)': attempting to reference a deleted function

Solution: https://github.com/Hconk/MNN/commit/819a666135a420f680675d503fabfa14028e13d2

//Session.hpp

private:
    std::map<MNNForwardType, std::unique_ptr<Backend>> mBackends;
    std::vector<std::unique_ptr<Pipeline>> mPipelines;
    std::vector<std::pair<int, std::shared_ptr<Tensor>>> mTensors;
    std::map<std::string, Tensor*> mInputs;
    std::map<std::string, Tensor*> mOutputs;
    bool mNeedResize       = false;
    bool mValid            = true;
    Backend* mFirstBackend = nullptr;

    Session(const Session&) = delete;
    Session(const Session&&) = delete;
    Session& operator=(const Session&) = delete;
    Session& operator=(const Session&&) = delete;

　So basically you can get MNN.lib with the MNN.dll.

4, this compiling Conver Tool [toss me the longest, as if burst foul language]

cmake  -G "Visual Studio 14 2015 Win64" -DCMAKE_BUILD_TYPE=Release -DMNN_BUILD_CONVERTER=ON ..

Q1, configuration protobuf

Under Win7, add the path environment variable protoc.exe located, and then run under cmd protoc.exe

Q2, tflite error

error lnk2019: error flatbuffers::ClassicLocale flatbuffers::ClassicLocale::instance_" (?instance_@ClassicLocale@flatbuffers@@0V12@A)

Solution: Add MNN-master \ 3rd_party \ flatbuffers \ src \ util.cpp to tflite project

So basically you can compiled a
