# Optional: use Hugging Face Space SDK = docker (set `sdk: docker` in README.md).
#
# IMPORTANT:
# - If your Space is on CPU hardware, `torch.cuda.is_available()` will be False no matter what.
# - If your Space is on GPU hardware, you must use a CUDA-enabled base image (below),
#   otherwise CUDA won't be visible inside the container.
