Build and install OpenCV from source with CUDA and cuDNN support

Hi @s1n7ax! Thank for your help but I face some trouble to install open CV. Could you answer my question
If I use (base) - virtual environment created by anaconda. can I import cv2 in (base) to used in pytorch? and I installed Cuda and CuDNN but not like you so any difference between your install process and my.
Sorry for my bad english and thank you so much for your help

I installed and didn't have errors. But when I run the final command "cv2.cuda.getCudaEnabledDeviceCount()" is returning me 0. Could be because I have CV2 installed using pip before?

i was succeed built cv2 with cmake, installed it perfectly and cuda support also. but how to put this libs into a virtualenv

This was very informative and great narrative. But i am having issues when i am doing the 2nd round of configuration. It says "Error in configuration process, project files maybe invalid". Could you please help me.

Is it possible to install this with anaconda ?

Nice video thanks ! . I have a question i noticed that you imported cv2 globally what if i use virtualenv in a project , how can i use the opencv gpu on my venv ??

This was indeed very helpful. I was not able to build with cuda support but now I can. Thanks a ton !

you are the best explanation

Nice Video. Thanks

--------- IMPORTANT ---------
Please add OPENCV_GENERATE_PKGCONFIG=1 flag in cmake-gui so other applications can find opencv.

If "nvcc not found" then create following soft links to local bin.
sudo ln -s /usr/local/cuda-11.3/bin/* /usr/local/bin
sudo ln -s /usr/local/cuda-11.3/nvvm/bin/* /usr/local/bin

Exact and thorough manual. Need to add Ubuntu 20.04 in the title for better indexing. Huge thanks!

Thankyou, it worked for me

I have done all the things you did in the video. and all things worked out perfectly fine. but in the last step when I write

import cv2
it is giving me ModuleNotFoundError: No module named 'cv2'

That was very helpful, thank you so much!
