One unfactional face track CHOP

General TouchDesigner Discussion

Hi everyone,

I’m having trouble getting TensorRT recognized in TouchDesigner 2025 (build 2025.32050, CUDA 12.9) on my Windows 11 laptop with an NVIDIA GeForce RTX 4060 GPU.

Here’s what I have done so far:

  1. Downloaded and extracted TensorRT 10.14.1.48 from NVIDIA official site.
  2. Verified that the bin folder contains nvinfer.dll, nvinfer_plugin.dll, and nvonnxparser.dll.
  3. Added the following folders to the system PATH:
    • D:\TensorRT-10.14.1.48.Windows.win10.cuda-12.9\TensorRT-10.14.1.48\bin
    • D:\TensorRT-10.14.1.48.Windows.win10.cuda-12.9\TensorRT-10.14.1.48\lib
  4. Restarted the computer.
  5. Tried copying the DLLs directly into the TouchDesigner bin folder.

Despite all this, TouchDesigner still shows:

“TensorRT is not found”.

I’ve checked CMD with where nvinfer.dll and it cannot locate the DLL, which makes me suspect it’s either a PATH / Python / CUDA runtime issue.

Has anyone encountered this with TD 2025 and RTX 40 series GPUs? Any advice on how to properly get TD to recognize TensorRT would be greatly appreciated!

Thanks in advance!

Sorry for the confusion there. You do not need to download TensorRT separately to use the Face Track CHOP.

What you will need to download is the correct Nvidia AR SDK for your particular GPU which includes all of the AI models and necessary dependencies (including nvinfer.dll). Currently, TouchDesigner is using the 0.8.7 SDK, so you download that version for the RTX 40 Series to work with your 4060 GPU.
