The deep network quantizer cannot be used, please see the picture for details？

[Xiao Yangcong]

I have set up the C++ compiler, but it still cannot be used.

Hi Xiao,

It looks like you are using "MinGW" as the C++ compiler. Unfortunately, quantization workflow does not support "MinGW" at the moment as mentioned in https://www.mathworks.com/help/deeplearning/ug/quantization-workflow-prerequisites.html. You can use a compiler provided by Microsoft (Microsoft Visual C++ 2017 or Microsoft Visual C++ 2015.) instead.

Please tell me how to choose Microsoft (Microsoft Visual C++ 2017 instead of MinGW C++ compiler ? Thanks

Hi @Meruzhan Hovhannisyan, you can follow the steps in https://www.mathworks.com/help/matlab/matlab_external/choose-c-or-c-compilers.html to select the compiler you want.

Thanks for the reply. But exactly as you say, I'm trying to choose MS compiler, but a message comes out that for C++ matlab finds only WinMG64 compiler, which is not supported by the quantization APP.

You likely do not have Microsoft Visual compiler installed in your machine. If you do, but "mex -setup C++" is not able to locate it, then please raise a technical support case from https://www.mathworks.com/support/contact_us.html
