To learn how to install the NVIDIA CUDA drivers, CUDA Toolkit, and cuDNN, I recommend you read my Ubuntu 18.04 and TensorFlow/Keras GPU install guide - once you have the proper NVIDIA drivers and toolkits installed, you can come back to this tutorial. If you have an NVIDIA GPU on your system but have yet to install the CUDA drivers, CUDA Toolkit, and cuDNN, you will need to configure your machine first - I will not be covering CUDA configuration and installation in this guide. CUDA Toolkit and cuDNN configured and installed.The CUDA drivers for that particular GPU installed.This tutorial makes the assumption that you already have: Step #1: Install NVIDIA CUDA drivers, CUDA Toolkit, and cuDNN Figure 1: In this tutorial we will learn how to use OpenCV’s “dnn” module with NVIDIA GPUs, CUDA, and cuDNN.
With all that said, let’s start configuring OpenCV’s “dnn” module for NVIDIA GPU inference. Don’t be discouraged! Take the time to understand the commands you’re executing, what they do, and most importantly, read the output of the commands! Don’t go blindly copying and pasting you’ll only run into errors. Even with my detailed guides, you will likely make a mistake along the way. Compiling OpenCV from source can be challenging if you’ve never done it before - there are a number of things that can trip you up, including missing packages, incorrect library paths, etc.
You are capable of reading terminal output and diagnosing issues.Again, this tutorial is not for those brand new to the command line. If you’re unfamiliar with the command line, I recommend reading this intro to the command line first and then spending a few hours (or even days) practicing. We’ll be making use of the command line in this tutorial.

If you intend to use a GPU for deep learning, go with Ubuntu over macOS or Windows - it’s so much easier to configure. When it comes to deep learning, I strongly recommend Unix-based machines over Windows systems (in fact, I don’t support Windows on the PyImageSearch blog).

Jump Right To The Downloads Section How to use OpenCV’s ‘dnn’ module with NVIDIA GPUs, CUDA, and cuDNN To learn how to compile and install OpenCV’s “dnn” module with NVIDIA GPU, CUDA, and cuDNN support, just keep reading! We’ll then benchmark the results and compare them to CPU-only inference so you know which models can benefit the most from using a GPU. Then, in next week’s tutorial, I’ll provide you with Single Shot Detector, YOLO, and Mask R-CNN code that can be used to take advantage of your GPU using OpenCV. In today’s tutorial, I show you how to compile and install OpenCV to take advantage of your NVIDIA GPU for deep neural network inference.
Led by dlib’s Davis King, and implemented by Yashas Samaga, OpenCV 4.2 now supports NVIDIA GPUs for inference using OpenCV’s dnn module, improving inference speed by up to 1549%! That all changed in 2019’s Google Summer of Code (GSoC). That wasn’t too much of a big deal for the Single Shot Detector (SSD) tutorials, which can easily run at 25-30+ FPS on a CPU, but it was a huge problem for YOLO and Mask R-CNN which struggle to get above 1-3 FPS on a CPU. However, the biggest problem with OpenCV’s dnn module was a lack of NVIDIA GPU/CUDA support - using these models you could not easily use a GPU to improve the frames per second (FPS) processing rate of your pipeline.
