emlc_compilationError.mat

Hi there, I was trapped in this error within the whole day. I'm using yolo to dectect objects, while I'm just using it but not trying to compile it. So when I used single or multiple CPUs to run the vehicle_Dataset, I found the training process was unable to be accomplished as matlab was out of memory.

So I turned to try to deploy the taining using my GPU, which is Geforce GTX 1060. I installed the new divers for this Graphic card(ver 430.64), CUDA toolkit 10.1, cuDNN v7.5.1 (April 22, 2019) for CUDA 10.1. Then I created

Variable name: CUDA_PATH
Variable value: C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1

in the system variables. Also, I added

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\lib\x64
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\extras\CUPTI\lib64

in the Path.

All the add-on on this page was also installed:

https://ww2.mathworks.cn/help/vision/ug/code-generation-for-object-detection-using-yolo-v2.html?searchHighlight=yolo&s_tid=doc_srchtitle

including "GPU Coder Interface for Deep Learning Libraries support package", Microsoft Visual Studio 2017, "MATLAB Support for MinGW-w64 C/C++ Compiler".

Then, I ran the following code in matlab, which worked very good.

mex -setup:'C:\Program Files\MATLAB\R2018b\bin\win64\mexopts\msvc2017.xml' C -v
mex -setup:'C:\Program Files\MATLAB\R2019a\bin\win64\mexopts\msvc2017.xml' C -v

Then I ran

coder.checkGpuInstall('gpu','codegen','cudnn','quiet');

Matlab inform me as

Error using coder.checkGpuInstall (line 32)
One or more of the system checks did not pass, with the following errors ...
Basic Code Generation: (Test GPU code generation failed with the error 'emlc:compilationError'. View report for further information: View report)

So I click the View report, and it says:

Build error: C++ compiler produced errors. See the Build Log for further details.

While the build logs has 1659 lines... I have attached the ecported reports in tha attachment. So I detected the current setup with coder.checkGpuInstall();

Compatible GPU           : PASSED 
CUDA Environment         : PASSED 
	Runtime   : PASSED 
	cuFFT     : PASSED 
	cuSOLVER  : PASSED 
	cuBLAS    : PASSED 
cuDNN Environment        : PASSED 
Basic Code Generation    : FAILED (Test GPU code generation failed with the error 'emlc:compilationError'. View report for further information: View report)

So could anyone help me out of this problem? Thanks a lot in advance!

I just solved the problem.

You need to first install visual studio 2015 or later (including C++).

Then type this in the command window:

mex -setup C++

you may have something like this:

MEX configured to use 'Microsoft Visual C++ 2015' for C++ language compilation.
To choose a different C++ compiler, select one from the following:
MinGW64 Compiler (C++)  mex -setup:'C:\Program Files\Polyspace\R2021a\bin\win64\mexopts\mingw64_g++.xml' C++
Microsoft Visual C++ 2015  mex -setup:C:\Users\Majid\AppData\Roaming\MathWorks\MATLAB\R2021a\mex_C++_win64.xml C++

Just click on "Microsoft Visual C++ 2015" link.

then check the coder again:

coder.checkGpuInstall

I had the same issue and I use 'Microsoft Visual C++ 2017' for C++ language compilation, but when I ran the

coder.checkGpuInstall

still I have this error

Basic Code Generation    : FAILED (Test GPU code generation failed with the error 'emlc:compilationError'. View report for further information: View report)

could you give me any advice for this problem?
