# ⭐ <FONT SIZE="+3">ComfyUI portable enhanced edition</FONT> ⭐ |
|
|
- Updated 22th December 2025 with ComfyUI version `0.5.1` |
|
|
|
|
|
The current official ComfyUI portable has two slight disadvantages, firstly it does not come with Git portable which is occasionally required by custom node packs or |
|
|
to automatically models etc, and the latest versions come with Python 3.13 by default which still has (few) compatibility issues with some extensions. |
|
|
|
|
|
So I am updating this version based on Python 3.12 with the latest updates and included Git and the [ComfyUI-Manager](https://github.com/Comfy-Org/ComfyUI-Manager) node. |
|
|
Recently I added some custom scripts with which you can easily modify the embedded Python environment too. |

This portable version contains all components required to use ComfyUI without needing to install any additional components. 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: |
|
|
|
|
|
* Latest Microsoft Visual C++ Redistributable Installer |
|
|
https://aka.ms/vc14/vc_redist.x64.exe |
|
|
|
|
|
After you unzip the archive you will find a few batch files in the main directory which must be used to run and modify the portable environment. |
|
|
|
|
|
* <FONT COLOR="white"><B>run_nvidia_gpu_v2.bat</B></FONT> |
|
|
This file sets up the necessary environment variables and launches ComfyUI |
|
|
|
|
|
* <FONT COLOR="white"><B>run_nvidia_gpu_v2_fast_fp16_accumulation.bat</B></FONT> |
|
|
Same as above but enables fast FP16 accumulation. |
|
|
|
|
|
* <FONT COLOR="white"><B>run_nvidia_gpu_v2_sageattn.bat, run_nvidia_gpu_v2_flashattn.bat</B></FONT> |
|
|
Same as above but enables the corresponding alternate attentions. |
|
|
|
|
|
* <FONT COLOR="white"><B>install_sageattn1.bat, install_sageattn2.bat, install_flashattn.bat</B></FONT> |
|
|
These install the corresponding versions of Sage or Flash Attention into the Python environment. |
|
|
**Only use this if you know what you are doing!** |
|
|
|
|
|
* <FONT COLOR="white"><B>get-models.bat</B></FONT> |
|
|
On a fresh install you will be missing a few essential/popular models and this file will download them for you. |
|
|
|
|
|
* <FONT COLOR="white"><B>environment.bat</B></FONT> |
|
|
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!** |
|
|
|
|
|
* <FONT COLOR="white"><B>change-pytorch.bat</B></FONT> |
|
|
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!** |
