1. torch.cuda.is_available()

https://pytorch.org/docs/stable/generated/torch.cuda.is_available.html

Return a bool indicating if CUDA is currently available.

Return type

bool

2. torch.cuda.is_available()

import torch

device = 'cuda' if torch.cuda.is_available() else 'cpu'  # examples: 'cpu', 'cuda', 'cuda:0', 'cuda:1', etc.
device_type = 'cuda' if 'cuda' in device else 'cpu'  # for later use in torch.autocast

print("device =", device)
print("device_type =", device_type)
