hi, when I tried installing opencv using cmake, I get an error saying "error in configuration process, project files may be invalid". How to fix this please help.
how do i include the paths needed in my project on pyinstaller? i always get these errors after the .exe has been built regarding the opencv; " File "PyInstaller\loader\pyimod03_importers.py", line 546, in exec_module File "PyInstaller\loader\pyimod03_importers.py", line 546, in exec_module File "cv2\__init__.py", line 102, in File "cv2\__init__.py", line 62, in bootstrap File "cv2\__init__.py", line 60, in load_first_config ImportError: OpenCV loader: missing configuration file: ['config.py'].

If you have module not found error, you may need to launch python from anaconda terminal using "python" instead of the shortened "py". I had it installed properly, but spent forever trying to fix it because of this stupid thing. Apparently py does not launch the anaconda activated or anaconda base environment, but launches some other version of python. Hope this helps someone else.
At the time of recording this tutorial, it worked on GTX1050 amd GTX1060. Not sure now after release of new versions of opencv, cuda, and visual studio.

Worked perfectly. Please mention how long it takes to build as it took me more than an hour and I thought of stopping it in between, glad I didn't do it. Thanks
@@TheCodingBug I found the "problem" : you forgot to mention one cmake setting. I was building for ALL supported CUDA architectures instead of the latest (8.6). Changed that and now I compile in less than 30 minutes. Seems like you should mention it.
Hi, @TheCodingBug, I followed your all steps, but last command didn't generate cv2 library. and and during running, I found a warning message. "error C2065: 'DIFFERENT_SIZES_EXTRA' : undeclared identifier [C:\OpenCV_Build\build\modules\world\opencv_test_cudawarping.vcxproj]". Kindly resolve my issue.
I am trying to configure OpenCV 4.6 in the virtual environment. However, the program is unable to detect numpy even after running the --upgrade command of numpy to the latest version. I even checked whether numpy is installed in the virtual environment, even after numpy being installed, CMake is still not detecting the numpy version in the NUMPY_INCLUDE_DIRS section. After several attempts, I even manually copied the numpy's installed path in the virtual environment to the NUMPY_INCLUDE_DIRS slot to see atleast if that works. It still won't detect numpy's version. It still mentions python3 bindings unavailable. How to solve this? Your assistance on this would be greatly beneficial.
I followed the steps as mentioned in the tutorial. But opencv build was not available for python3 (3:40 in the tutorial). I deleted build and configured again and now opencv build is available for python3. Even I did not downgrade numpy as specified in the tutorial. Hope this helps for someone !!!
There are some functions in cv2 that can use GPU acceleration. You can see it in action in my other tutorial "Face Detection Using OpenCV with CUDA GPU Acceleration"

It would be a good idea to do a video on steps to update opencv and tensorflow gpu versions. Always afraid I mess up something if I simply uninstall the previous version.
That's true. For tensorflow, it's really easy. Just see the supported cuda and cudnn versions against a particular tensorflow version and install them. Use Anaconda for that. For opencv, it becomes headache though.

@@jonarad9955 it seems your IDE is using a virtual environment. You have to build for that environment as well or change IDE settings to use base Python environment. Also, make sure there are no multiple Python distributions installed (let's say Anaconda and native Python).
Is it also possible to perform all the setups for installing opencv with gpu support with both native installation of python and anaconda or we just need to keep Anaconda ?

For those who have not found python 3 even after updating numpy I found same error but it was due to my anaconda path was not set in system environment variables when I did that it installed properly and opencv was build properly without any error
I hope it helps someone else.
@@TheCodingBug Thankyou for such great effort it was the best tutorial for opencv cpu installation short and clear👍keep up the good work
hi how did you do it?
@@kristelquezon4624 I did everything as mentioned in the video but build for python was still unavailable so when I completed the whole process i found that in the end the python folder would be missing which would contain the main file
Then after that I tried to recheck what was missing and I found that my anaconda path was not there in system environment variable so when I added that the error disappeared you can just search environment variable in your windows search bar you will find two things i found two things environment variable for lenevo(I have legion 5 pro) and below was system variable try to add your required python path to 'system' variable
After clean installation...
I am facing this error:

Nice tutorial. It is worked and I resolved my problem to implement opencv with gpu.
I am glad it was helpful.
Thanks man...I follow your tutorial and it works..
helping others out. don't use the console command he gives. (if it's not populating the install folder)
instead do this in the build folder (assuming the install folder should be in the build folder)
cmake --build . --config Release
cmake --install . --config Release
instead of anaconda3 it shows this path C:/Users/Jatin/AppData/Local/Programs/Python/Python37-32/Lib/site-packages
how to handle?pls help
Looks like you have multiple versions of Python. You can change all the paths to Anaconda.

If you have module not found error, you may need to launch python from anaconda terminal using "python" instead of the shortened "py". I had it installed properly, but spent forever trying to fix it because of this stupid thing. Apparently py does not launch the anaconda activated or anaconda base environment, but launches some other version of python. Hope this helps someone else.
Thank you for sharing your experience. Maybe it'll help someone.

got as far as to upgrading numpy which was succesfull then I hit cmake configure but it doesnt change anything while compiling I see "no numpy module"

I am trying to configure OpenCV 4.6 in the virtual environment. However, the program is unable to detect numpy even after running the --upgrade command of numpy to the latest version. I even checked whether numpy is installed in the virtual environment, even after numpy being installed, CMake is still not detecting the numpy version in the NUMPY_INCLUDE_DIRS section. After several attempts, I even manually copied the numpy's installed path in the virtual environment to the NUMPY_INCLUDE_DIRS slot to see atleast if that works. It still won't detect numpy's version. It still mentions python3 bindings unavailable. How to solve this?
Your assistance on this would be greatly beneficial.
I followed the steps as mentioned in the tutorial. But opencv build was not available for python3 (3:40 in the tutorial). I deleted build and configured again and now opencv build is available for python3. Even I did not downgrade numpy as specified in the tutorial. Hope this helps for someone !!!
i did it but still doesn't available for python3 however i've tried every way
you just explained the procedure, but not why you are doing what you are doing, would be great if you did
There are some functions in cv2 that can use GPU acceleration. You can see it in action in my other tutorial "Face Detection Using OpenCV with CUDA GPU Acceleration"

It would be a good idea to do a video on steps to update opencv and tensorflow gpu versions. Always afraid I mess up something if I simply uninstall the previous version.
That's true. For tensorflow, it's really easy. Just see the supported cuda and cudnn versions against a particular tensorflow version and install them. Use Anaconda for that.
For opencv, it becomes headache though.

@@jonarad9955 it seems your IDE is using a virtual environment. You have to build for that environment as well or change IDE settings to use base Python environment.
Also, make sure there are no multiple Python distributions installed (let's say Anaconda and native Python).
Is it also possible to perform all the setups for installing opencv with gpu support
with both native installation of python and anaconda or we just need to keep Anaconda ?
You can do it with native Python too.
