We'll activate the virtual environment for the install at F:!NeuroNet\InvokeAI.

What happened

I have cleaned the entire system from InvokeAi. I've installed different versions. I've uninstalled everything that can be uninstalled. I've updated everything that can be updated. I've reinstalled the models 4 times. It doesn't fucking work. This shit don't work.

What you expected to happen

This shit should work.
