Just an update, I was able to make it use only the 3060 by adding
export CUDA_VISIBLE_DEVICES=0
to gui.sh
To list your device IDs, you can enter
python3 -c "import torch; print([(i, torch.cuda.get_device_properties(i)) for i in range(torch.cuda.device_count())])"

That could be it. I guess in the TV show, the writers are trying to show that Monk is an old fashioned guy who uses outdated terms.
