The default version is CPU only, which usually is not what we want if we have a GPU:
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121
Now cuda enabled pytorch apps like whisper etc... can take advantage of CUDA finally!
False means it is not working, or at least your cuda/nvidia driver setup is installed and True means good.
python3 -c "import torch; print(torch.cuda.is_available())"
True
