🚀 DaSiWa ComfyUI Installer

This script provides a one-click installation experience for ComfyUI, optimized with uv for maximum speed. It automatically handles environments, GPU detection, and my curated set of Custom Nodes - needed for my workflows.

This installer is "evergreen" - it will always download and updated versions of the installer and all logic from his repository.

🚫👾The Installer is open source and virus free. Virustotal can proof this by testing on 61 AV engines.

✨ Features

1. uv-Engine: Uses uv for package management—up to 10x faster than standard pip.

2. Portable Python: Automatically manages an isolated Python 3.12 environment. No system-wide Python installation or Admin rights required.

3. Hardware-Aware: Intelligent detection for NVIDIA (Pascal through Blackwell/50-series), AMD, and Intel GPUs with optimized Torch mapping.

4. Smart Node Sync: Automated installation of nodes from custom_nodes.txt, supporting Git submodules and editable packages (| pkg).

5. Self-Healing Logic: The installer automatically checks for logic updates and launcher improvements on every run.

6. Sage-Attention v2: The installer can optionally try to build and install Sage-Attention v2 into the portable environment.

7. Starters: Creates convenient "run_comfyui" starters with predefined parameters (inside the ComfyUI folder).

🛡️ Zero-Conflict Design

This installer is designed to be "invisible" to your operating system:

• Ignores Windows Store Aliases: It bypasses the "fake" Python links that often break AI installations.

• No Admin Rights: Since Python is downloaded as a portable folder, you don't need administrator privileges to "install" it.

• Strict Versioning: By locking to Python via config.json, we ensure high-performance libraries like Triton and SageAttention remain stable.

🛠️ Prerequisites

• GPU: An NVIDIA, AMD, or Intel GPU (required for automated Torch optimization).

• No Python Installation Required: The installer now uses uv to automatically download and manage a portable, isolated Python environment. You do not need to install Python on your system manually.

• Internet Connection: Required for the initial download of the portable Python binary and ComfyUI components.
