I'm running this on Google Colab

!pip install deface
!pip install onnx==1.15.0
!pip install onnxruntime-gpu==1.16.2
!pip install tensorrt==8.6.1.post1

!deface /content/gdrive/MyDrive/input_video/a.mp4 --replacewith mosaic  --thresh 0.4 -o /content/gdrive/MyDrive/input_video/a_blur.mp4

This has nothing to do with this repo. Your tensorrt lib is not linked correctly.

See as references:
NVIDIA/TensorRT#2596
NVIDIA/TensorRT#1817

For me I had to do this:

python3 -c "import tensorrt; print(tensorrt.__path__)"

Output
['/usr/local/lib/python3.10/dist-packages/tensorrt']

The lib for me was actually under (so scoop around a bit in your package folders):
/usr/local/lib/python3.10/dist-packages/tensorrt_libs

echo $LD_LIBRARY_PATH

/usr/local/nvidia/lib:/usr/local/nvidia/lib64

As you can see the lib was not in my path.
You can add it via:

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/lib/python3.10/dist-packages/tensorrt_libs"

afterwords it should look like this:
echo $LD_LIBRARY_PATH

/usr/local/nvidia/lib:/usr/local/nvidia/lib64:/usr/local/lib/python3.10/dist-packages/tensorrt_libs

Hope it helps
