Hello,

I want to test my machine learning code on GPU environment but it doesn't work.

I constantly getting warnning below

Warning: The CUDA driver must recompile the GPU libraries
because your device is more recent than the libraries.
Recompiling can take several minutes. Learn more.
>In run_MNIST_pinv (line 9)

and continuously another errors erupt

Error using gpuArray/hTimesTranspose
Call to dgemm in CUBLAS failed with error status:
CUBLAS_STATUS_EXECUTION_FAILED.
...
    etc

so I want to fix warnning(require recompile the GPU libraries) first to solve these errors

how can I recompile the GPU library

ref. my HW

OS : ubuntu 18.10

CPU : AMD Ryzen Threadripper 2990WX

GPU : NVIDIA Geforce RTX2080 Ti

MATLAB ver : R2018b

I already checked GPU driver version.!

Thanks !

Did you try rebooting?

Yes, I already did, but the messages still rise

This is a known issue with CUDA 9.1 and the new Turing generation of GPUs. You don't need to do anything except ignore the initial warning or error.

There are multiple issues. The warning about recompiling of libraries is spurious and not relevant. The error from cublas is one-time only. And there is an equivalent error in cuDNN. A permanent workaround is to put the following into your startup.m file:

warning off parallel:gpu:device:DeviceLibsNeedsRecompiling
try
    gpuArray.eye(2)^2;
catch ME
end
try
    nnet.internal.cnngpu.reluForward(1);
catch ME
end

Hello, I added the startup.m file to the path as you said and restarted matlab. However, when I re-run the following code, I still get the previous error
