Thank you so much! I've been working on getting cv2 to work with cuda support for days and with your help I finally found the problem: I was using VS 2022 instead of 2019. After uninstalling my mess of VS versions and doing a clean 2019 install, it worked w/o a hitch. Awesome stuff!

[daffiduck]

I am using VS 2022 Professional and this works fine no issues thanks bro !

[gabrielsemonis]

Awesome tutorial. One question though, how can i use the cv2 package in other virtual environments? I tried creating a sym link from the virtual env site packages folder to the base anaconda cv2 package but importing fails

6:20 I didn't understand how to choose the correct bin number. Why did you let 6.1:8.6? Is it the range of your GPU's transistors?

Python 3.11.10 | packaged by conda-forge | (main, Oct 16 2024, 01:17:14) [MSC v.1941 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'cv2'

What do I get this? The configuration and installation went successfully. I'm using VS 2019, CUDA 11.8, compatible CUDnn and numpy, Python 3.11. Could it be the version of Python, as I notice you're using 3.9?

It looks like the cv2 folder in the environment was never created. This --target INSTALL command should have copied the necessary OpenCV files to the installation directory, which I specified.

I did what you said excitely with CUDA11.3, CMAKE2.4.2, OPENCV4.5.2(and contrib) but when i want to try the last thing of import cv2 example i gave that error and i think it couldn't installed correctly.
I tried almost 20 hours it but i couldn't success.
what can i do please help me.

>>> import cv2
Traceback (most recent call last):

Hello there. Im stuck at 6:13. It does not show me Cuda Fast math at this point. Which step did i miss

[ankithreddy]

I tried many times but there is an error showing up
error C4430: missing ty
pe specifier - int assumed. Note: C++ does not support default-int (compiling source file

[badassaman]

its saying that
Traceback (most recent call last):

[eddygonzalez]

Hello, I have been googling and I have not found anything regarding feature extraction (ORB, SIFT, SURF) for CUDA in python, where could I find some information, everything that appears is in C++, could someone help me?

[daniel_blackWindy]

" The library is compiled without CUDA support in function 'throw_no_cuda' "
somebody face this issue?
opencv : 4.6
python : 3.9.13
cuda version : 11.7

[seregasame]

thanks for the video! I did it. how do I create a python package from this build that can simply be installed on another computer?

[jojoii]

Visual Studio 2019 can no longer be downloaded. Does it work with the 2022 version as well?

[Anndres]

Nice tutorial mate, I had a lot of issues but following everything step by step IT WORKED. I used regular python (not Anaconda) :)

[QuarktaschemitSenf]

Sorry but the step at 6:50 was way too fast. Can u explain how i get the correct number with a certain graphics card? E.G. i work with a RTX 3050 mobile. How to set the correct number at arch bin ? Or is this step not important?

[EBINHD]

ive literally struggled an week with this and still cannot get it to work
"module 'cv2' has no attribute 'dnn'"

[EBINHD]

itd be nice to specify cuda version since 12 seems to not work..?

[abdelhaksaouli]

am getting DLL load failed while importing cv2: The specified module could not be found.
