CUDA 11.3 not being detected by PyTorch [Anaconda]
I am running Ubuntu 20.04 on GTX 1050TI. I have installed CUDA 11.3.

Anaconda PyTorch isn't detecting CUDA:
&gt; import torch
&gt; torch.cuda.is_available()
&gt; False

Any ideas how to solve the issue?

The solution:
Conda in my case installed cpu build. You can easily identify your build type by running torch.version.cuda which should return a string in case you have the CUDA build. if you get None then you are running the cpu build and it will not detect CUDA
To fix that I installed torch using pip instead :
pip3 install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu113
