I have this same issue- the program appears to primarily use CPU and very little GPU.
Same here NVIDIA RTX 2800
You have to switch a window, for example the "copy" window into "Cuda", then it will look as you would've expected it.
@Alec55555 I am sorry, I didn't really understand what you mean by "copy window into Cuda". I am simply following the tutorial as it is. How do I do what you have suggested?
@ahmedahmedov No problem, use this tutorial https://michaelceber.medium.com/gpu-monitoring-on-windows-10-for-machine-learning-cuda-41088de86d65
@Alec55555 After switching the window, it stll shows that GPU utilization is 0%, although the reply of torch.cuda.is_available() is TRUE...Can you give me your conda list? I want to know which part do I miss...Thank you very much!
@ahmedahmedov and @soberirving this article can give you some more detail on what the entries in Task Manager mean. Since you are not 3D rendering you will not see much show up under 3D. Like what @Alec55555 said you have to switch the graph to the CUDA view.
This is what you are expecting to see for your GPU under CUDA.
You can also run nvidia-smi
to get some more detail but it will show limited information. This is because on Windows the Driver Display Manager (WDDM) manages memory.
$ ./nvidia-smi.exe

Compared to a Linux system you will have far more information available to you.
