PyTorch is a popular deep learning library that can be used with CUDA to accelerate computations. To use PyTorch with CUDA, one must have a CUDA-enabled GPU and the appropriate version of PyTorch installed.
The code above checks whether CUDA is available on the system. If it returns
True, then CUDA is available and can be used with PyTorch.
To use CUDA with PyTorch, one must also specify the device to be used for computations. This is done by setting the
device to either
"cpu" in the code.
device = torch.device("cuda")
This code sets the device to be used for computations to
Finally, one must also ensure that the CUDA-enabled GPU is correctly detected by PyTorch. This is done by setting the
CUDA_VISIBLE_DEVICES environment variable to the index of the GPU to be used.
In the example above, the environment variable is set to
0, which means the first CUDA-enabled GPU on the system will be used.
Once these steps are completed, PyTorch can be used with CUDA to accelerate computations.
