I searched for a few days all over the internet for a proper guide on how to do this but after many fails i decided to ask here. Here is the error code from webui: Launching Web UI with arguments: xformers WARNING:xformers:WARNING[XFORMERS]: xFormers can't load C++/CUDA extensions. xFormers was built for: PyTorch 2.1.2+cu121 with CUDA 1201 (you have 2.0.1+cu118) Python 3.10.11 (you have 3.10.11) Please reinstall xformers (see https://github.com/facebookresearch/xformers#installing-xformers) Here are versions from pip: torch 2.3.0+cu121 xformers 0.0.26.post1 I have CUDA 12.1.1 with VS2022 installed.

Did you install using pip or using the installer? Do you have Python 3.11 installed from Python.org, or from the Windows app store?

Something here seems to be in disagreement: xformers says about your torch: "you have 2.0.1+cu118", but pip says torch 2.3.0+cu121. Somehow xformers isn't seeing the same torch that pip is seeing.

Try to delete your virtual environment and reinstall Invoke using the installer from https://github.com/invoke-ai/InvokeAI/releases/download/v4.2.4/InvokeAI-installer-v4.2.4.zip.
