Original GitHub issue: https://github.com/Comfy-Org/desktop/issues/1563

App Version

desktop [v0.7.5]

Expected Behavior

I installed the custom node because I want to use AILab_QwenVL, but the AILab_QwenVL node doesn’t appear—only Qwen VL (GGUF) is available.
So I tried using Qwen VL (GGUF) instead, but when I do, this warning pops up and it won’t run.

Actual Behavior

It doesn’t run, and warning message pops up.

ComfyUI Error Report

Error Details

  • Node ID: 98
  • Node Type: AILab_QwenVL_GGUF
  • Exception Type: RuntimeError
  • Exception Message: [QwenVL] llama_cpp is not available. Install the GGUF vision dependency first. See docs/GGUF_MANUAL_INSTALL.md

Originally created by @yomkii on GitHub (Jan 28, 2026). Original GitHub issue: https://github.com/Comfy-Org/desktop/issues/1563 ### App Version desktop [v0.7.5] ### Expected Behavior I installed the custom node because I want to use AILab_QwenVL, but the AILab_QwenVL node doesn’t appear—only Qwen VL (GGUF) is available. So I tried using Qwen VL (GGUF) instead, but when I do, this warning pops up and it won’t run. <img width="1589" height="578" alt="Image" src="https://github.com/user-attachments/assets/99411349-1709-4480-bc4f-61c88e283545" /> ### Actual Behavior It doesn’t run, and warning message pops up. # ComfyUI Error Report ## Error Details - **Node ID:** 98 - **Node Type:** AILab_QwenVL_GGUF - **Exception Type:** RuntimeError - **Exception Message:** [QwenVL] llama_cpp is not available.

Hi @yomkii! I'm Dosu and I’m helping the desktop team.

Your issue is caused by missing or failed installation of the llama_cpp (llama-cpp-python) dependency, which is required for Qwen VL (GGUF) and related nodes to work. The logs show repeated failures to install this package, and import errors for both llama_cpp and parts of transformers needed by AILab_QwenVL. This prevents the node from loading and appearing in the UI.

Here’s how to troubleshoot and resolve this:

  1. Use the built-in terminal in ComfyUI Desktop to ensure you are installing dependencies in the app’s .venv (not your system Python). Open the terminal from the ComfyUI Desktop menu.

  2. Manually install the required dependencies for the QwenVL node. In the terminal, run:

    .venv\Scripts\python.exe -m pip install -r custom_nodes\ComfyUI-QwenVL\requirements.txt
    

    If there is no requirements.txt, try:

    .venv\Scripts\python.exe -m pip install llama-cpp-python
    

    Watch for any error output and save it for diagnosis if the install fails.

  3. If installation fails with a build error, make sure you have the required build tools:

    • Visual Studio 2019 or later with the Desktop C++ workload and Spectre-mitigated libraries installed (details).
    • Microsoft Visual C++ Redistributable (latest version).
  4. Check for version conflicts: The default transformers version in ComfyUI Desktop is pinned to 4.57.3, but AILab_QwenVL may require a newer version for AutoModelForVision2Seq. If you see import errors, try installing a compatible version:

    .venv\Scripts\python.exe -m pip install "transformers>=4.38.0"
    

    (Check the QwenVL node’s documentation for the exact required version.)

  5. If the virtual environment seems broken or corrupted (e.g., persistent import errors, missing modules), close ComfyUI Desktop, delete the .venv folder in your install directory, and restart the app. This will force a clean environment rebuild and reinstall dependencies.

  6. After each step, restart ComfyUI Desktop and check if the AILab_QwenVL node appears and loads without errors.

  7. If you continue to see errors, collect the full error output from the terminal and logs. This will help diagnose if the issue is a missing dependency, a build tool problem, or a version conflict.

For more details on installing custom nodes and dependencies in ComfyUI Desktop, see the official guide and custom node dependency docs.

If you’re still stuck after these steps, let me know the exact error output from the failed pip install and I can help further.
