Failed to build opencv-python ERROR: Could not build wheels for opencv-python, which is required to install pyproject.toml-based projects

[lzhhh93]

Hi everyone, I am trying to install opencv-python 4.7.0.72 in unbuntu and it shows that no wheels can be built. My pip has updated to 21.2.1 and Python version is 3.9. Apprecitae for any tipps. Thanks a lot.

@lzhhh93 Your build log clearly says that you are using Python version 3.6, not 3.9.... Please update to recent Python. Python 3.6 has been deprecated.

Experiencing a similar issue with Python3.11, found those stack overflow workaround as well but no luck here either.

Defaulting to user installation because normal site-packages is not writeable

               If you are seeing a compilation error please try the following steps to
               successfully install cmake:
               1) Upgrade to the latest pip and try again. This will fix errors for most
                  users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
               2) If on Linux, with glibc < 2.12, you can set PIP_ONLY_BINARY=cmake in
                  order to retrieve the last manylinux1 compatible wheel.
               3) If on Linux, with glibc < 2.12, you can cap "cmake<3.23" in your
                  requirements in order to retrieve the last manylinux1 compatible wheel.
               4) Open an issue with the debug information that follows at
                  https://github.com/scikit-build/cmake-python-distributions/issues

           ********************************************************************************
           scikit-build could not get a working generator for your system. Aborting build.
     
           Building Linux wheels for Python 3.11 requires a compiler (e.g gcc).
           But scikit-build does *NOT* know how to install it on raspbian
     
           To build compliant wheels, consider using the manylinux system described in PEP-513.
           Get it with "dockcross/manylinux-x86" docker image:
     
             https://github.com/dockcross/dockcross#readme
     
           For more details, please refer to scikit-build documentation:

@Matsoosterlaken Me too, seems like OpenCV does not support Python 3.11 till now.

[Armin-H]

@skvark I'm trying to install opencv-python 4.7.0.72 on Ubuntu and I'm using python 3.6 .
I know that python 3.6 is depricated but I have to use python 3.6 for some project. Is this possible to install opencv-python 4.7.0.72 on python 3.6 ?

[Vishu9519]

I'm also facing the same issue.
I'm trying to install opencv-python on my HPC server. I've created an environment, while most of the packages are getting installed, for some reason opencv-python is giving error.

[mstixenberger]

any updates on this?
i have the same problem when installing opencv on a raspberry pi (running in docker with different python-base images (tried from 3.8 until 3.11, nothing works so far))

[liondk]

Hi
Any update about this?
I'm facing the same issue with my Pi4

[omrode1]

try installing an earlier version of OpenCV, like in my case the following version worked. pip install opencv-python==4.5.3.56

[fankai17277]

yes, try installing a earlier version of OpenCV .

[hossein890]

I have also problem with installing the package

consider installing python3-dev or python3-devel using yum and update setuptools with pip and setuptools wheel ,it worked for me with opencv-python-headless when it cant build wheel

I'm having this same issue trying to build a wheel for openCV on my raspberry pi 3. I installed dnf so I could do what you said, Using didn't work, because it said that there were no enabled repositories in /etc/yum/repos.v or /etc/yum.repos.v . What commands would you use to update your setuptools and wheel with pip? Should I use pip3 since the program is for python3?

I apologize, I am fairly new to this and taking over someone else's project so there has been a lot of unknown variables. Thank you for the help!

I also met this problem. I solved this by trying pip install opencv-python==<latest version to older version>, till pip install opencv-python==4.6.0.66 successed

[bob020416]

Try using conda install py-opencv solve for me
