Hello, I have been trying for the past week to get a Tesla K80 setup on Ubuntu 20.04 To use with OpenCV DNN.
I am able to get the drivers for the card installed and running: nvidia-smi shows Tesla K80 4 times (I have 2 cards installed). When building OpenCV, I see the Cuda is enabled (YES) however DNN is not. I see the the “backend” is not built, but as soon as I attempt to install the Cuda-Toolkit, the machiene will no longer be able to see the cards nvidia-smi. And the OpenCV Build still says NO for DNN. I am banging my head against the wall trying to figure this one out. Would anyone please give me a hint???
Here is a more complete output:
