ComfyUI portable environment enhanced edition https://huggingface.co/datasets/Xeno443 ============================================================================================================================= This ComfyUI portable version has been enhanced to include * a portable Git, which is sometimes needed to download additional custom node components * ComfyUI-Manager for easy custom node management * Keeping Python v3.12.10 for maximum compatibility Everything else is unchanged from the original ComfyUI portable. The only thing your system needs are the Microsoft Visual C++ runtimes, but if you are not using a naked Windows install it is very likely that you already have those. If you don't have them you can download them here: ## Microsoft Visual C++ 2015-2022 Redistributable https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#visual-studio-2015-2017-2019-and-2022 The original startup bat files remain unchanged and as such will not be able to use Git if you don't have a system-wide install. Use the "_v2" versions to make sure the portable environment is set up correctly. Usage ===== ## run_nvidia_gpu_v2.bat This file sets up the necessary environment variables and launches ComfyUI ## get-models.bat On a fresh install you will be missing a few essential/popular models and this file will download them for you. ## run_nvidia_gpu_v2_fast_fp16_accumulation.bat Same as above but enables fast FP16 accumulation. ## run_nvidia_gpu_v2_sageattn.bat Starts ComfyUI with support for Sage Attention. You first must install Sage Attention support! ## run_nvidia_gpu_v2_flashattn.bat Starts ComfyUI with support for Flash Attention. You first must install Flash Attention support! ## install_sageattn1.bat, install_sageattn2.bat, install_flashattn.bat These install the corresponding versions of Sage or Flash Attention into the Python environment. Only use this if you know what you are doing! ## environment.bat Starts a cmd.exe within the portable environment. You can use this to manually modify the embedded Python. Only use this if you know what you are doing! ## change-pytorch.bat This allows you to switch to a different Pytorch version, or just reinstall the current one if you encounter issues. Only use this if you know what you are doing! |
