I managed to upgrade CUDA to 11.8 on AGX Xavier with JetPack 5.1 inside a container nvcr.io/nvidia/l4t-pytorch:r35.2.1-pth2.0-py3 . but after that, I could not use Pytorch on GPU as torch.cuda.is_available() returns False. Any suggestions? dusty_nv 2023 年7 月 31 日 14:...

我们可以使用torch.cuda.is_available()去检测本地是否有GPU能够使用。接下来,我们将通过torch.device设置该GPU,让他能在整个教程中使用。.to(device)方法也用来将张量和模块移动到想要使用的设备上。 代码为: device = torch.device("cuda"iftorch.cuda.is_available()else"cpu") 即如果有CUDA就使用它,没有就...
Model Parallelism with Dependencies Implementing Model parallelism in PyTorch is pretty easy as long as you remember two things. The input and the network should always be on the same device. toandcudafunctions have autograd support, so your gradients can be copied from one GPU to another during...
cudaFreeAsync(ptrB, stream); It is now possible to manage memory at function scope, as in the following example of a library function launchingkernelA. libraryFuncA(stream); cudaMallocAsync(&ptrB, sizeB, stream); // Can reuse the memory freed by the library call ...

Processing takes a long time and only CPU is used in the display: In the log file also appears the error entry "Failed to create CUDAExecutionProvider". in PyTorch GPU works as expected. I can see that both in the processing speed and in the load on VRAM. ...
