Retro diffusion uses its own virtual environment, so you need to do all of the python library management there, you can find the venv location in "Help" -> "Retro Diffusion Tools" -> "Open Python Venv Folder"
Thanks for replay! I've tried to update manually all torch packages in local directory, but looks like there are some incompatibility with them.
Ah, thats unfortunate. We'll be supporting 50xx cards officially once pytorch has stable support, but until then you'll need to hold tight :)
