ERROR: Failed building wheel for opencv-python: [ FileNotFoundError: [Errno 2] No such file or directory: '_skbuild/linux-armv7l-3.9/cmake-install/python/cv2/config-3.py' ]
I tried to install opencv-python in my virtual environment and was expecting the opencv-python library v4.7.0.72 to be installed succesfully.
Even after multiple tries and trying different solutions/workarounds found online, nothing seems to help.
The build runs for +-3 hours, goes to 100% and then later on fails during installation phase of the project.
Following error is being returned:
FileNotFoundError: [Errno 2] No such file or directory: '_skbuild/linux-armv7l-3.9/cmake-install/python/cv2/config-3.py'

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.9 from "/home/username/Desktop/MyApp/venv/bin/python"
* The NumPy version is: "1.19.3"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

I had the same problem. Try it "sudo apt install python3-opencv"
Hi billni, thanks for your answer.
I've tried that as well, but that installs it globally and not in my virtual environment.
I need it to be in my virtual environment, since I want to package the application with all dependencies into single binary from that virtual environment.
It looks like I was able to reproduce the issue with my Pi 3b. Will take a look if I can propose some workaround before the next release.
Cheers, much looking forward to this
config-XXX.py is named differently depending on LIMITED_API option. https://github.com/opencv/opencv/blob/4.x/modules/python/common.cmake#L210
CI build enabled LIMITED_API by default and it works well.
You can add -DPYTHON3_LIMITED_API=ON to CMake options to work around the issue.
See https://github.com/opencv/opencv-python/blob/4.x/setup.py#L179 and https://github.com/opencv/opencv-python/blob/4.x/setup.py#L251

Thank you very much. So its simply pip3 install opencv-python -DPYTHON3_LIMITED_API=ON --verbose
Or is that completely wrong?
I can see your little eyes looking! When you said fixed I presumed I would just run the install again and it should work?! A little more help is needed please, Alexander @asmorkalov :) I have spent weeks trying to get OpenCV working and every guide I have tried has failed! I don't see how it's so bloody hard to install?!
All I'm looking to do is run the NDVI script using my RPI 3B+ and NOIR V3 camera! I don't know if it helps but I could instal OpenCV on my Unraid server and have the feed from the Pi go there and the server does all the hard work. At the end of the day, my server is running Home Assistant in a VM but I need the Pi's NOIR camera with the blue filter over the lens.
PHmm, I think I can clone this one and do it. Numpy, picamera and flask is already installed so will try cloning this and installing…Kind regards,JamieOn 17 Mar 2023, at 14:26, Olli-Pekka Heinisuo ***@***.***> wrote:

Thanks for the fix @asmorkalov !
Is it correct this should now be available in the opencv-python-rolling deployment package?
I tried to install this by using "pip install opencv-python-rolling==4.7.0.20230318"
But it seems te version can't be found.
On piwheels.org it says the build is skipped? => https://piwheels.org/project/opencv-python-rolling/
Should I take a different approach?
Sorry if this is a dumb question, i'm pretty new to this.
Thanks in advance!
Rolling releases are broken for today. I'm working on it right now. I'll let you know, when you can try.
Any update? @asmorkalov Cheers
I had no luck with #820, but pinning the scikit-build version in pyproject.toml to 0.17.1 everything worked again (without this 0.17.3 is installed):
--- "scikit-build>=0.13.2",
+++ "scikit-build==0.17.1",
I tested 0.17.2 and it fails with
AttributeError: 'NoneType' object has no attribute 'replace'
This was fixed in 0.17.3, but there seems to be some other change in there that's breaking things. Is there any reason to not pin this version for the builds?
This build failure is still present with python3.11. It appears to be caused by #835 — the incompatible numpy version apparently disables the python bindings since I can see that "install path" is omitted from the cmake version string no matter the value of -DCMAKE_PYTHON3_INSTALL_PATH. Updating numpy to a compatible version allowed me to build a wheel with 3.11. CI doesn't have this issue because of the TEST_DEP_LATEST override.
Should be fixed by #839.

I tried to build opencv-python package into docker and got same error. How can I handle it?

"sudo apt install python3-opencv"
It's bad idea. The command installs yet another OpenCV-Python instance of some old version provided by Linux distribution. Doing that you get a salad of several instances of OpenCV that is loaded in inpredictable order. You can switch to distro-provided OpenCV Python, but all other instanced should be removed first.
Anyway that didn't help
How did you solve your problem? I encountered similar issue on RPi 4B

Probably, I installed numpy before running setup.py. Also here you can check my working Dockerfile for building wheel
Thank you for your reply! The Dockerfile looks not much different from #814 (comment)
Did you find the reason of this error message?

I resolved the issue with building opencv-python source manually. (latest release one)
ChanJoon, thank you for your suggestion.
Rather than go down the rabbit hole of a manual installation I searched for "installing opencv rpi" and found the following comment:
The standard command to install opencv is pip install opencv-contrib-python but don’t immediately run this (!) as it will try to install the latest versio of OpenCV, which is not always fully functional on the Raspberry Pi. Furthermore, the installation may take a very long time. Therefore I recommend to run the below command that installs the latest known working version. Here I use 4.5.3.56 but it could be that already a newer stable version is available
Using instructions on this site:
https://singleboardblog.com/install-python-opencv-on-raspberry-pi/
and after installing the prerequisites I used this command:
pip install opencv-python-headless==4.5.3.56
This installed opencv very quickly, but obviously for an earlier version.
I know that this thread is not about DVR-Scan but to install it I then used:
pip install dvr-scan[opencv-headless]
Progress at least.
We had this issue recently and found it was due to cmake not creating the opencv python library cv2.abi3.so. Check back on the build logs from cmake and look at the lines that say:
-- OpenCV modules:
-- To be built:
make sure that python3 is in this list (as it likely isn't). Further up in the logs I could then see the following error:
-- Found PythonInterp: /venv/bin/python3.10 (found suitable version "3.10.13", minimum required is "3.2")
-- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython3.10.so (found suitable exact version "3.10.13")
Traceback (most recent call last):
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'numpy'
For me the fix was just to install numpy first. Change the Dockerfile in #814 (comment) to install it before build:
- RUN python3.10 -m pip install scikit-build
+ RUN python3.10 -m pip install scikit-build numpy
dpkg --list | grep python3-dev
ii libpython3-dev:armhf 3.9.2-3 armhf header files and a static library for Python (default)
ii python3-dev 3.9.2-3 armhf header files and a static library for Python (default)
6 hours later...

Pretty much always the same thing; this was with 4.9.0.80.
