Hi,

This error stops training when the 'ExecutionEnvironment' is 'parallel', 'multi-gpu', or 'gpu'. Training is running uninterrupted when set to 'cpu'. I'm running code for the first time on Ubuntu 20.04.2 LTS system with Intel i9 12 core cpu and 2x 3070 gpu's. It indicates only 12 workers and seems to not recognize the gpus.

Any suggestions and help is welcome.

Thank-you

After some investigation (see thread below), this problem seems to be limited to RTX 3080 and 3070 and Linux. It can be worked around by disabling tensor cores. Restart MATLAB and run

setenv NVIDIA_TF32_OVERRIDE 0

before you do anything else. Further investigations are under way to look for a solution that doesn't require this workaround, which will reduce performance.

Original answer:

Are you running MATLAB release R2021a? The 3070 is not supported on earlier releases.

Joss, sorry I didn't get this earlier. Here is the output from the attempted training (ExecutionEnvironment 'multi-gpu'):

Hi Joss,

This workaround is no longer working. Do we have any progress on the toolboxes/GPU issues?

Here is what I'm seeing:

training network....

Error using trainNetwork (line 184)

GPU support for deep neural networks requires Parallel Computing Toolbox and a supported GPU device.

Error in deepLearnUCSF (line 139)

trainedNet = trainNetwork(imagesTrainds, lgraph, options);

Caused by:

Error using feval

Unable to find a supported GPU device. For more information on GPU support, see GPU Support by Release.

I restarted MATLAB and have: setenv NVIDIA_TF32_OVERRIDE 0 at the top of my code. Here are the trainingOptions I'm using. Fustrated that this expensive machine is not being used. Hope there's help on this...

Thanks,

Scott

This is fixed in the next update of MATLAB R2021a, however you'd be better off simply downloading R2021b which will be out in a week or so.

Unfortunately NVIDIA weren't able to provide us with a fix that has no effect on performance, but we can at least limit the workaround to the problematic convolutions. A proper fix will arrive with the next CUDA upgrade.

We've never seen this problem on Windows.
