Please share your tips, tricks, and workflows for using this software to create your AI art. py its not a user file and will be replaced when updated. py", whether that be in a . bat `sfast. 0 Uninstalling torch-2. sh file, or in the command line, you can just add the --lowvram option straight after Activate the Virtual Environment: Enter the following command: call . 6 seconds per iteration~ Actual Behavior After updating, I'm now experiencing 20 seconds per iteration. Beta Was this translation helpful? Give feedback. bat and it will install it or do I have to do it another way? Currently I have --opt-sdp-attention --medvram in my webui-user. At the same time, we developed a few workflows that are just tailored to specific tasks (for example, testing different VAEs), and having the whole chain in front of us really helps us ensure that we are changing just one thing You signed in with another tab or window. - comfyanonymous/ComfyUI You signed in with another tab or window. 5 of VRAM. 2+cu118 with CUDA 1108 (you have 2. D:\AI\ComfyUI>call conda activate D:\AI\ComfyUI\venv-comfyui Total VRAM 8188 MB, total RAM 65268 MB xformers version: 0. 4780] (c) Microsoft Corporation. org (it's like discord but If you use xformers this option does not do anything. Toggle table of contents Pages 6. xFormers was built for: Also if you could do: python_embeded\python. When I installed comfy it showed loading xformers [version] when I started it. 3. To enable higher-quality previews with TAESD, download the taesd_decoder. Scoured the internet and came across multiple posts saying to add the arguments Adding --xformers to the commandline args will allow every Added an option to allow building dedicated engines for different models. Since the latest git pull + restart comfy (which also updates front end to latest), every workflow I open shows groups and spaghetti noodles/lines stuck in place in smaller resolution in upper left, while the nodes themselves can be resized bigger or smaller. 2. 24 ComfyUI: 2921e83063. ormers and If you use xformers this option does not do anything. py", line Launching Web UI with arguments: --force-enable-xformers Cannot import xformers Traceback (most recent call last): File "Z:\stable-diffusion-webui\modules\sd_hijack_optimizations. The above output is from comfyui. You signed out in another tab or window. They are not combined to allow for cases such as loading the model as FP16 to save VRAM, calculating in FP32 because GPUs based on Kepler for example do not support FP16. Installing xFormers We recommend the use of xFormers for both inference and training. Generating 48 in batch sizes of 8 in 512x768 images takes roughly ~3-5min depending on the steps and the sampler. 5. org (it's like discord but You signed in with another tab or window. Well, Stable Diffusion WebUI uses high end GPUs that run with CUDA and xformers. library. org (it's like discord but Hi @MoonMoon82, you will need to install xformers in your comfyui environment. variant="fp16", use_safetensors=True ) pipe. Traceback (most recent call last): File "C:_ComfyUi\ComfyUI\nodes. But then why does AUTOMATIC 1111 start with the message "No module 'xformers'. You can use it to achieve generative keyframe animation(RTX 4090,26s) 2D. (Example: 4:9). pth, taesd3_decoder. Please use `sfast. activate venv by using . Out of curiosity I disabled xformers and used Pytorch Cross attention expecting a total collapse in performance but instead the speed turned out to be the same. Learn how to update comfyui xformers using the Command Prompt and pip to access the latest features and enhancements. [AnimateDiff] - [0;31mERROR [0m - No models available Figured out why it happens, xformers attention code currently has a limit for the size of the first dimension of the tensor passed in. bat IMO neither should be defaulted to on unless users enabled them, because both methods aren't appropriate for any serious work. py still uses xformers . Installing collected packages: torch, xformers Attempting uninstall: torch Found existing installation: torch 2. 1 but I install pytorch version 2. I am working on a refactor of the motion module code to adhere to ComfyUI latent dim standards instead of animatediff's original implementation with a different latent setup. There's no point in conditionalizing for mac unless you have one old enough to run a CUDA card that's useful enough to run stable diffusion models, or maybe one of the more recent Intel mac pros with Windows running on it if apple didn't block NVidia hardware from working. Next (Vladmandic), VoltaML, InvokeAI, and Fooocus. A friend of mine for example is doing this on a GTX 960 (what a madman) and he's experiencing up to 3 times the speed when doing inference in ComfyUI over Automatic's. VRAM is sufficient for most tasks, but if I use Redux and then enable IPadapter v2 for Flux, OOM happens. 1) mismatches the version that was used to compile PyT So far, we feel that working with it a slightly more overhead than working in Auto1111, but we have a lot more experience with the latter. 12 + PyTorch 2. Set up a reverse proxy such as Nginx to forward all incoming connection requests to the backend port 8188 to enable access to the ComfyUI interface. exe -m pip list we can see what torch version you are running. And really: my old RTX 1070 card runs better with --opt-sdp-attention than before with xformers. upivrq cqql kymbkps skefd yicky onlqj nmyw rwaed eoq glwl
