>>53783384Assuming you're familiar with command line and have installed Python 3.10.6 or 3.10.8 on your operating system with commandline and “Add Python to PATH”. implementation enabled and Git Bash beforehand, Stable Diffusion requires a virtual environment folder (venv) with about 1.7GB to start. To start doesn't mean that's ALL you need -- checkpoints can average on 2GB a pop, including the required checkpoint your installation might run and install. Some Stable Diffusion installations will set up the venv for you, so it shouldn't be a problem to start these days but I still recommend familiarizing yourself with commandline just to run updates and stuff.
I would recommend running Stable Diffusion off a secondary drive if you have one, you really don't need to have it running on your OS disk since eventually you might end up running around 40-60GB of extensions alone (mostly checkpoints and VAE files, some extensions too for LoRAs and LoCons+LoHas as well and whatever fits your needs). I have bulky hard drives so I can eat that but I still forget most users don't walk around with terabyte loads of disk space.
You also SHOULD NOT run commandline or any Stable Diffusion Batch files as an Administrator, that'll fuck up your updates..
