Hello friends,
I am working with MATLAB R2020b on Window 11, Nvidia GeForce RTX 1050 Ti. I have installed the latest Nvidia driver, as well as CUDA 10.2. I get the error below after running
gpuDevice
Error using gpuDevice (line 26)
Unable to find a supported GPU device. For more information on GPU support, see GPU Support by Release.
Can someone kindly help me resolve this problem? Thanks

Your post says Nvidia GeForce RTX 1050 Ti, but that black image says RTX 3050 Ti. That could make a notable difference in your R2020b release. IIRC Ampere was not supported in R2020b.

You have to enable support for Ampere in R2020b.

Hi @Joss Knight, what you said is painfully true. I ran some deep learning regression after forward compatibility; and the RMSE was virtually constant after about 10 epochs. I have to resort to an older PC. Once again, thanks very much.

Hiya. I was only expecting that your GPU's performance might not be that great - but it wouldn't make any difference to whether or not a model will work, only how long it takes to train. If you're not seeing any improvement when training your model, maybe you need to change the model or the training parameters.
