📝Easy Guide: Installing Triton, Sage Attention, and Teacache for ComfyUI Portable (Windows)

👉🏾Prerequisites

GPU Compatibility: 

• RTX 40xx (Ada) and RTX 30xx (Ampere): Fully supported.

• RTX 50xx (Blackwell): Support is very new and requires the latest software.

• RTX 20xx (Turing) and older: Limited compatibility – you may experience issues.

📂Step 1: Check Your ComfyUI Setup

• Open your ComfyUI directory.

• Check if there’s a folder named python_embeded inside it.

• (If you previously installed extensions using Triton, you might already see a libs folder inside python_embeded. If not, don’t worry—we’ll add it later.)

👩🏾‍💻Step 2: Install Triton

Triton is required for SageAttention to work properly. There are two options here:

1️⃣ Standard Installation:

• Open a Command Prompt (Win + R → type cmd → hit Enter).

• Navigate to your ComfyUI folder using the command:

cd path\to\ComfyUI_windows_portable

(Replace path\to\ComfyUI_windows_portable with your actual folder location.)

• Run the following command to install Triton:

python_embeded\python.exe -m pip install -U triton-windows

• Note: If the package “triton-windows” isn’t found on PyPI, download the appropriate wheel—e.g., triton-3.2.0-cp312-cp312-win_amd64.whl—from here, place it in your ComfyUI folder, and install it with:

python_embeded\python.exe -m pip install path\to\triton-3.2.0-cp312-cp312-win_amd64.whl

(Replace path\to\... with the actual file path.)

2️⃣ Pre-release Version (if needed):

If you need the pre-release version (Triton 3.3), use:

python_embeded\python.exe -m pip install -U --pre triton-windows

👨🏾‍💻Step 3: Install Sage Attention

Run this command in the same Command Prompt window:

python_embeded\python.exe -m pip install -U sageattention

Note: If you see a deprecation warning about loading an egg (e.g., sageattention-2.0.1-py3.12-win-amd64.egg), it’s recommended to first upgrade pip:

python_embeded\python.exe -m pip install --upgrade pip

Then force a reinstall if necessary:

python_embeded\python.exe -m pip install --force-reinstall sageattention

🔍Step 4: Install Teacache

Teacache is an optional but useful caching tool that speeds up processing.

Note: You can now install it via the ComfyUI Manager. Open the Manager, go to the "Custom Nodes Manager", search for “comfyui-teacache”, and install it.

or click "Install via Git URL" with https://github.com/welltop-cn/ComfyUI-TeaCache

📂Step 5: Add Missing libs and include Folders

If Triton doesn’t work right away, you may need to add libs and include manually:

• Download the required files:

  • If you’re using ComfyUI Portable v0.2.4 or later (with Python 3.12.7), get them from here: 👉 Download include & libs folders

  • If you have a different Python version, check for compatible files:
    👉 Alternative versions here

• Extract the downloaded ZIP and place the include and libs folders inside:

  📁ComfyUI_windows_portable\python_embeded\

  🚨 Important: Ensure you place them correctly:

  • ✅ python_embeded\libs (not python_embeded\Lib)

  • ✅ python_embeded\include

🚦Step 6: Verify Installation

• Open ComfyUI and try running an Sage Attention workflow: https://www.patreon.com/posts/black-mixtures-2-124117186

• If you experience issues, go back and make sure:

  • Triton installed correctly (triton-windows shows up in pip list)

  • Your libs and include folders are in the right place.

🔨Troubleshooting

• Command Not Found?
  Ensure you’re running commands from inside the ComfyUI directory.

• Sage Attention Not Working?
  Reinstall it using:

python_embeded\python.exe -m pip install --force-reinstall sageattention

• Triton Compilation Errors?

  • Make sure you have Visual C++ Redistributable installed:
    👉 Download VC Redist

  • Restart your computer and try again.

• Still not working?

  • Send me a DM on Patreon or Discord, or comment below and I'd be happy to help troubleshoot this!

March 24th, 2025 Update - V1.0

We've put together an EXPERIMENTAL sage attention & triton installer which you can download below. (Still working on the additional features)

• Place the "BlackMixture-sage-attention-installer.bat" file in your ComfyUI portable root directory.

• Click "run anyway" if you receive a pop up from Windows Defender. (There's no viruses in this file. You can verify the code by right-clicking and opening with notepad. As I'm not a programmer, this was written using LLMs based on this text guide article)

• I recommend starting with these options (as the others are more experimental):

  • 1: Check system compatibility

  • 3: Install Triton

  • 4: Install Sage Attention

  • 6: Setup include and libs folders

  • 9: Verify installation
