I’m encountering some issue where torch.cuda.is_available() returns False even though I’ve correctly installed the NVIDIA driver on my Linux machine. I’ve tried to reinstall pytorch in a new environment using pip and conda, neither worked either.
Here are the details when I run collect_env:
<frozen runpy>:128: RuntimeWarning: 'torch.utils.collect_env' found in sys.modules after import of package 'torch.utils', but prior to execution of 'torch.utils.collect_env'; this may result in unpredictable behaviour

/home/edward/Documents/default_venv/lib/python3.11/site-packages/torch/cuda/__init__.py:141: UserWarning: CUDA initialization: CUDA unknown error - this may be due to an incorrectly set up environment, e.g. changing env variable CUDA_VISIBLE_DEVICES after program start. Setting the available devices to be zero. (Triggered internally at ../c10/cuda/CUDAFunctions.cpp:108.)

I’ve gone through many post looking for solutions yet have not figured this out yet. Your insights would be greatly appreciated!
