                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

Write here what went wrong.

Steps to reproduce

architecture (e.g. x86)
opencv-python version

Issue submission checklist

[ ] This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
[ ] I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
[ ] The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
[V] I'm using the latest version of opencv-python

PIP I didn't solve.

But I found out a way to download and compile. There was a ram not enough error with self compiling. This was solved by increasing the swap. The Raspberry PI 3B+ ram is 1GB, not enough for compiling.

sudo dphys-swapfile swapoff
sudo vim /etc/dphys-swapfile # swap 100MB to 2GB

then compile again:

sudo git clone https://github.com/opencv/opencv.git
sudo git clone https://github.com/opencv/opencv_contrib.git

cd opencv
sudo mkdir build
cd build
sudo cmake

sudo make -j2
sudo make install

It takes quite a while. Must be patient.

Build directory, if the hardware is not too different, may be it might work for others.

Expand the build
make install

Until now the installation from source like you did worked for me and takes a long time for sure, BUT I wasn't able to really use OpenCV (tab completion functions). My IDE and OS showed me both, that the import is possible, but when I ran code it's without a behaviour.
