I want 3 versions of pytorch

How do i have 3 version of pytorch readily available for comfyUI?

I have an old quadro m2000 graphics card which is not supported by the latest version of pytorch for comfyui, so I’d like to use an old version of pytorch for that, i have a new gfx card arriving soon so i want the latest version of pytorch available and i want to use the CPU version of pytorch for a laugh

For the Quadro M2000, keep a separate ComfyUI virtual environment with the older PyTorch build, then make another venv for the new GPU and a third CPU-only environment; each launcher can point at its own Python executable. That avoids trying to make one environment load incompatible CUDA wheels, and switching becomes a reversible change of which launcher you start.

thanks for your reply ,

do you have an article you can point me to for the comfyui virtual environment? if i used that as search terms on google id get irrelevant results.

do you mean typing in venv into the terminal to get a virtual environment?

ive typed in venv before into terminal when i was just being told how do things but I suppose I’ll have to learn more about it?

Are they irrelevant, or are you just unsure what you’re looking for? When I use that exact phrase to search Google, the first result is a guide for installing ComfyUI into a virtual environment, which is exactly what you need here.

ok thanks, im completely new to this. Would have taken hours to understand just from reading around not knowing where to look.

I’ve got enough information now! thanks

Yes, by a virtual environment I mean a separate Python environment for each ComfyUI setup. venv is the tool that creates one; typing the word alone usually does not create it.
