# This uses https://github.com/asomoza/image_gen_aux/blob/main/src/image_gen_aux/upscalers/README.md
# Also this space has been duplicated from their official huggingface space, https://huggingface.co/spaces/OzzyGT/basic_upscaler
# They did great work, and I was happy to see them to also use my models :) I thought Id duplicate it and extend it.
# It basically made me get a pro account so I can make a Zero GPU space and made me upload a lot of my models on huggingface now so I can use them here ;)
# This is the community version of my previous Image Upscaler space at https://huggingface.co/spaces/Phips/Upscaler, where instead of only my own models, I will add models per the model authors request to ensure
# that the model author is aware of, and desires, their model to be usable in this space.
# I made a file additionally that lists and links to models https://huggingface.co/spaces/Phips/CommunityUpscaler/blob/main/models.md

# My models
