AssertionError: Torch not compiled with CUDA enabled

[MasterDNK00]

I'm trying to run the python scripts/knn2img.py, but I constantly get the following error.

Traceback (most recent call last): File "scripts/knn2img.py", line 314, in <module> model = load_model_from_config(config, f"{opt.ckpt}") File "scripts/knn2img.py", line 60, in load_model_from_config model.cuda() File "C:\Users\sinan\anaconda3\envs\ldm\lib\site-packages\lightning_fabric\utilities\device_dtype_mixin.py", line 72, in cuda device = torch.device("cuda", torch.cuda.current_device()) File "C:\Users\sinan\anaconda3\envs\ldm\lib\site-packages\torch\cuda\__init__.py", line 778, in current_device _lazy_init() File "C:\Users\sinan\anaconda3\envs\ldm\lib\site-packages\torch\cuda\__init__.py", line 284, in _lazy_init raise AssertionError("Torch not compiled with CUDA enabled") AssertionError: Torch not compiled with CUDA enabled

Please kindly advise me on how to fix this.
