great

yes both - I have to update all of my tensorRT again but that is ok. Hopefully, I won't have to update again in awhile.

ok now working right?

on my fresh install: now my settings are: version: v1.7.0 • python: 3.10.11 • torch: 2.1.2+cu121 • xformers: 0.0.23.post1 • gradio: 3.41.2 • checkpoint: 6ce0161689 on my original SD install: I performed these steps with error above and it now works.. uninstalled torch from .bat commandline, installed pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121, and updated xformers from 0.0.23 to 0.0.23.post1, deleted tensorRT extension and reinstalled with your install .bat file and it works again latest config: version: v1.7.0-285-g15ec54dd • python: 3.10.11 • torch: 2.1.2+cu121 • xformers: 0.0.23.post1 • gradio: 3.41.2 • checkpoint: a58017353f

basically I want to install the latest version of torch and xformers to get latest speed improvements. I was using tensorRT successfully and it really helps - I don't know how I missed the patreon update a few months ago..

trying to do similar comparison and ran into torch update error. I was on xformers 0.0.20 and torch 2.0.1. I updated xformers to 0.0.23 with pip install xformers==0.0.23 and it also update torch to 2.1.1 After install I get this error "RuntimeError: Torch is not able to use GPU; add --skip-torch-cuda-test to COMMANDLINE_ARGS variable to disable this check" Any suggestions to how to perform these updates and ensure the proper dependencies? Thx
