Hi,
I have installed Cuda9.2 along with cudNN following the instruction given in NVIDIA site in Windows 10. I am going to use deep learning in MATLAB 2019b.
When I used ---> coder.checkGpuInstall('full')
I got the below error and messages:
Compatible GPU : PASSED
CUDA Environment : PASSED
Runtime : PASSED
cuFFT : PASSED
cuSOLVER : PASSED
cuBLAS : PASSED
cuDNN Environment : FAILED (Unable to find the 'NVIDIA_CUDNN' environment variable. Set 'NVIDIA_CUDNN' to point to the root directory of a NVIDIA cuDNN installation.)
TensorRT Environment : FAILED (Unable to find the 'NVIDIA_TENSORRT' environment variable. Set 'NVIDIA_TENSORRT' to point to the root directory of a TensorRT installation.)
Profiling Environment : PASSED
Basic Code Generation : FAILED (Test GPU code generation failed with the error 'emlc:compilationError'. View report for further information: View report)

cudnn: 0
tensorrt: 0
basiccodegen: 0
basiccodeexec: 0
deepcodegen: 0

Can anyone please help to resolve the issue?

You need Visual studio 2017 or earlier.
Run Matlab as administrator.

I have the same problem.
coder.checkGpuInstall()
Compatible GPU : PASSED
CUDA Environment : PASSED
Runtime : PASSED
cuFFT : PASSED
cuSOLVER : PASSED
cuBLAS : PASSED
cuDNN Environment : PASSED (Warning: Deep learning code generation has been tested with cuDNN v7.5. The provided cuDNN library v7.6 may not be fully compatible.)

What shuold I do

This is how I do it on Matlab R2023b + Window 10 x64
First I install CUDA 11.8
Then I install CUDNN 9.0 (it would be better to use CUDNN 8.7)
Then I do 3 copy steps
Copy step 1:
Copy all files from C:\Program Files\NVIDIA\CUDNN\v9.0\bin\11.8\ to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\bin\
Copy step 2:
Copy all files from C:\Program Files\NVIDIA\CUDNN\v9.0\include\11.8\ to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\include\
Copy step 3:
Copy all file from C:\Program Files\NVIDIA\CUDNN\v9.0\lib\11.8\x64\ to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\lib\x64\
Now I add the environment variables like this
Restart my computer and open matlab again. I then type
gpuEnvObj = coder.gpuEnvConfig;
gpuEnvObj.BasicCodegen = 1;
gpuEnvObj.BasicCodeexec = 1;
gpuEnvObj.DeepLibTarget = 'cudnn'; % it can be changed to 'tensort'
gpuEnvObj.DeepCodeexec = 1;
gpuEnvObj.DeepCodegen = 1;
results = coder.checkGpuInstall(gpuEnvObj)
Another test is to use gpucoderSetup on the matlab command prompt
You can then run checks

Hi Susama
Looks like the requisite environments for CUDNN and TENSORRT are not set correctly on your windows.
These environment variables should point to the location on your computer where these libraries were installed as described here
https://www.mathworks.com/help/gpucoder/gs/setting-up-the-toolchain.html
You can confirm if they are set correctly by running the following commands in MATLAB session
>> getenv('NVIDIA_CUDNN')
>> getenv('NVIDIA_TENSORRT')
If the above commands return empty , make sure to set the variables through you Windows's environment variable settings found via Control Panel ->System and Security->System->Advanced System settings.

Hi Jaya,
As per your given link, I already set the path and that can be seen from the below image. But when I tried your given code
>>getenv('NVIDIA_CUDNN')
I obtained below result:
ans
0x0 empty char array
So I would like to request you to let me know what variables I need to set in control panel.
Looking forward to hearing from you.
With regards
Susama

Ensure that cuDNN library is installed in the correct directory.
Check Nvidia’s official documentation for installing in Windows :
https://docs.nvidia.com/deeplearning/sdk/cudnn-install/index.html
These environment variables should point to the location on your computer where these libraries were installed as described here:
https://in.mathworks.com/help/gpucoder/gs/setting-up-the-toolchain.html
Important Note: The Operating system ( in your case , Windows 10) only uses environment variables which were made available when the system has started. So in order for windows 10 to be able to start using the new environment variables which you had just set you need restart your system. In other words, in order to use the new or edited environment variables you will need to restart your system.

Hi Sourabh, i've followed the steps on Nvidia's webpage, but the environment variable for cuDNN doesn't seem to autoset. I even tried adding it myself, but Matlab is not detecting it. As well, i'm getting the following error:
Error using coder.checkGpuInstall (line 33)
One or more of the system checks did not pass, with the following errors ...
cuDNN Environment: (Unable to find cuDNN header files in directory 'C:\Program Files\NVIDIA GPU Computing
Toolkit\CUDA\cuda\include'. Check that the cuDNN headers are installed with the specified cuDNN SDK.)
Error in PedestrianDetectionExample (line 31)
coder.checkGpuInstall(envCfg);
I've tried all sorts of troubleshooting available in matlab forums, but they're not helping. This is really urgent, so i'd appreciate any help. Thank you!

Hello
try this
% specify the CUDA install directory, you must have already copied cudnn files there
setenv('NVIDIA_CUDNN','C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.3')
% specify the TensorRT path
setenv('NVIDIA_TENSORRT','C:\Program Files\NVIDIA GPU Computing Toolkit\TensorRT-8.0.3.4.Windows10.x86_64.cuda-11.3.cudnn8.2\TensorRT-8.0.3.4')
coder.checkGpuInstall('full')
gpu: 1
cuda: 1
cudnn: 1
tensorrt: 1
basiccodegen: 1
basiccodeexec: 1
deepcodegen: 0
deepcodeexec: 0

how did you resolve deepcodegen and deepcodeexec . do i need to install opencv for it
if so how can i do this

Hi Muhammad,
You do not need to install OpenCV. You can resolve deepcodegen and deepcodeexec by downloading NVIDIA CuDNN and NVIDIA TensorRT libraries and setting the environment variables 'NVIDIA_CUDNN' and 'NVIDIA_TENSORRT' to point to the install folder.
Here is the documentation page of the config settings to test deepcodegen and deepcodeexec using coder.checkGpuInstall, for reference
