AssertionError: Torch not compiled with CUDA enabled

I tried

import torch
print(torch.cuda.is_available())

but returns false...

Any idea?

[tonywhite11]

go to pytorch and download the correct torch version

[tonywhite11]

go to pytorch and download the correct torch version

Uninstall the current version of PyTorch

pip uninstall torch

Install the correct version of PyTorch with CUDA support

pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu117

Verify the installation

python -c "import torch; print(torch.cuda.is_available())"

import torch
print(torch.cuda.is_available())

After completing these steps, you should be able to run your script without encountering the "Torch not compiled with CUDA enabled" error.

I can get further on Windows.
I have batch files here to install and run it.

I do have the issue that it runs super slow on Windows though that I am hoping a dev can help with eventually.
