You must install Visual Studio to use GPU Coder.

Hi @Joss Knight, I am using MATLAB 2019b version and have installed VS 2019 community version. I already have built MKLDNN library successfully but still getting the same error as of now.

Error is, MEX build failed: Build error: C++ compiler produced errors. See the Build Log for further details. <a href="matlab:helpview('C:/Program Files/Polyspace/R2019b/help/coder/helptargets.map','msginfo_Coder_FE_TargetBuildError');"

Solutions I already have tried are:

https://www.mathworks.com/matlabcentral/answers/761406-code-generation-error-build-error-c-compiler-produced-errors-see-the-build-log-for-further-deta which talks about placing mkldnn_config.h into mex file
https://www.mathworks.com/matlabcentral/answers/447387-matlab-coder-how-do-i-build-the-intel-mkl-dnn-library-for-deep-learning-c-code-generation-and-dep which talks about build mkl-dnn from source where I got the sucess.
mex -setup c++ link that matlab central provides.

I am working on a research project where I want to see the inference time by resnet50 model using resnet50.onnx model. My Question is,

Do we need the MEX build to perform inference from the generated c++ code? Because error is not coming in code generation.

If yes, then how to debug this error.

@Allan Condiman, @Walter Roberson and @Ali Al-Saegh are you able to solve this issue? If yes, please help.

This is a new question, not really a comment on the answer to an existing question. Try posting a new question, which might draw the attention of the GPU Coder team. That said:

Read the documentation for GPU code generation
Try coder.checkGpuInstall or the GPU Environment Check and Setup App. It might help work out why Visual Studio is not on the path.
MKL-DNN is for CPU execution, so either you don't have a GPU or you are building with the wrong target
You don't need to do code generation to run resnet50 in MATLAB, for instance, try:

net = resnet50;
x = imresize(im2single(imread('peppers.png')),net.Layers(1).InputSize(1:2));
predict(net,x)
ans = 1×1000
