Getting error for NVIDIA CudNN with Matlab 2021b in Windows 10, NIVIDIA T500

Similar to described in the previous post, I installed all MATLAB apps, 3rd party software and checked all environemental variables but I am unable to passe the Deep-learning code generation check (cuDNN and tensorrt).

I would realle appreciate your help?

Below, you can find the list of errors:

1. cuDNN

gpuEnvObj = coder.gpuEnvConfig;

gpuEnvObj.GpuId = 0;

gpuEnvObj.DeepLibTarget = 'cudnn';

gpuEnvObj.DeepCodegen = 1;

gpuEnvObj.DeepCodeexec = 1;

coder.checkGpuInstall(gpuEnvObj)

2. tensorrt

envCfg.DeepLibTarget = 'tensorrt';

envCfg.DeepCodegen = 1;

envCfg.Quiet = 1;

coder.checkGpuInstall(envCfg);

Hi Christian,

The errors are likely coming from the version mis-match of the CuDNN library. As mentioned in the warning, we have only verified deep learning code-generation against the CuDNN library v8.1 for MATLAB R2021b. Can you try installing v8.1 version and check if you can proceed with code-generation?

Thanks,

Sayan
