Import Failed - ModuleNotFoundError: No module named 'tensorrt'

[alex-mitov]

Hello,

I'm getting an "Import Failed" error in the ComfyUI manager with this node. I've installed it on the 2nd to last version of ComfyUI portable - v0.3.31-3-g80a44b97 (2025-05-04). Here's the error message:

Error message occurred while importing the 'ComfyUI_TensorRT' module.

Traceback (most recent call last):

    import tensorrt as trt
ModuleNotFoundError: No module named 'tensorrt'

Any ideas how to make it work?

I'm having the same problem...

This is likely because the installation of the custom node failed.

You can try re-running the installation.

Example if you use the Python embedded version of ComfyUI:

cd D:\ComfyUI-Latest\ComfyUI\custom_nodes\comfyui_tensorrt
D:\ComfyUI-Latest\python_embeded\python.exe -s -m pip install -r requirements.txt

This is the same issue as #102 and is fixed by running python.exe -s -m pip install wheel-stub in the python_embeded folder of your ComfyUI installation.
