opencv-dnn-cuda-test's Introduction

opencv-dnn-cuda-test

Sample code of testing functions of OpenCV with CUDA-enabled DNN modules.

Setting up

$ cd yolos
$ wget https://pjreddie.com/media/files/yolov3.weights
$ cd ..

Then go to either Python or C++ part to validate the installation of OpenCV with CUDA-enabled DNN modules.

Special Thanks

Thanks for YashasSamaga providing a quick dirty way to measure FPS. You can visit his work about this:

As C++ part, I adapted some lines from the following (written by YashasSamaga):

Also, he provides the way to compile OpenCV version 4.x without errors:

opencv-dnn-cuda-test's Issues

Missing yolov3.weights file

Line 9 of main.py has:

opencv-dnn-cuda-test/python_code/main.py

Line 9 in 2d56576

net = cv.dnn.readNet(model="../yolos/yolov3.weights", config="../yolos/yolov3.cfg")

But the file yolov3.weights is not anywhere in the repository.

Thus, executing the python test fails:

(opencv_cuda) jsalvo@rig01:~/projects/opencv-dnn-cuda-test/python_code$ python main.py
Traceback (most recent call last):
File "main.py", line 9, in <module>
net = cv.dnn.readNet(model="../yolos/yolov3.weights", config="../yolos/yolov3.cfg")

Failing to build cpp_code/main.cpp

Hi there,

Thanks for this repo to test out CUDA with DNN. I have built OpenCV 4.4.0 on Ubuntu 20.04 LTS and the Python verification works.

However, I am unable to build main.cpp under cpp_code directory. I am not a C++ programmer, but I would like to ensure that the all tests works fine. When I build as per README.md:

g++ -o opencv_dnn_cuda_test_cpp main.cpp -I/usr/local/include/opencv4 -lopencv_core -lopencv_dnn -lopencv_highgui -lopencv_imgcodecs

.. I get lots of linking errors, like complaining about OpenCL:

Can you suggest where I should start looking at what the problem is ?

how to use the maximum of GPU Capacity

Hello ,about utilization of GPU how can be improve it :
like you see when i tap command line watch nvidia-smi to wach utilization of GPU: i found that script python use just 985 MIb of GPU, my script need more resources of GPU . if you have a command line or lines python to accelerate it .
