Hello Jinghua,
I understand that you are facing an error on using the ‘gpuDevice’ function. You could follow the below suggestions which may help resolve the error:
- Ensure that no other process is using the GPU. Close any other applications that might be using the GPU resources.
- If you have a display GPU then you could try making the display GPU invisible using the following command:
setenv('CUDA_VISIBLE_DEVICES','0')
3. Try using the ‘reset’ function to reset the GPU device and clear its memory and then use the ‘gpuDevice’ function.
4. Virtual Machine support for MATLAB is not explicitly present. If you are using a virtual machine, you could face this error. NVIDIA provides the vGPU software which provides virtual machines the access to NVIDIA GPUs. Check out Virtual GPU Software documentation from NVIDIA to resolve the error.
5. Use the ‘coder.checkGpuInstall’ command to verify GPU environment. This can direct you to the root cause of the error by giving ‘FAILED’ status to that check. Try the suggestions that follow for each ‘FAILED’ check.
For more information on ‘coder.checkGpuInstall’ and the ‘reset’ methods, refer to the following MathWorks documentations:

Hope this helps!
