Jetson Nano Opencv CNN model

Hello Experts,
I am trying to use the default face_recognition (dlib, Pillow, numpy, etc) models in python as part of opencv2 library. When I tried to run it with CNN based models then the device hangs.


Does it has support GPU accelerator support internally linked or anyway to use the GPU engine of Jetson Nano to run CNN models ?


If your library is built with CUDA support, it should use cuDNN for inference automatically.
To check if dlib has GPU support, you can test it with the following command:

import dlib.cuda as cuda


Its throwing error as follows,

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'dlib.cuda'

How Can i install the dlib for CUDA


You can find some information for building dlib with GPU support here:
