Expected behaviour

compile opencv-python on rabsian 10 (buster, Linux raspberrypi 4.19.57+ #1244 Thu Jul 4 18:42:50 BST 2019 armv6l GNU/Linux) from source directly, no cross compile without exception

Actual behaviour

are setup.py:69 or setup.py:83 deprecation warnings already hinting at the upcoming exception?

Please check the name of the cv2.cpython-37m-something-something.so, it seems that the regex pattern does not match with the resulting binary name. I don't have a Raspberry Pi available so I can't check this myself.

Where would the resulting binary be?

The build output should be under cmake-install/python/.

Something like this:

/home/pi/opencv-python.git/_skbuild/linux-armv6l-3.7/cmake-install/python/

i build opencv-python in an arm arch machine, it also can't find the file and lack of the cmake-install/python/

and finally, i found it out, i have two python versions installed, as py3 and py2, and it seems the cmake try to build py2, but my py2 lack of the numpy and i want to use the py3 for building ....

i modify the setup.py, and add the

-DPYTHON_DEFAULT_EXECUTABLE=/usr/local/python3.7/bin/python3.7

for cmake args , now it works well

Hi, I am trying to build opencv-python on an AArch64 machine running Ubuntu 20.04. I get the error mentioned above.

...
Traceback (most recent call last):
  File "setup.py", line 439, in <module>
    main()
  File "setup.py", line 188, in main
    skbuild.setup(
  File "/usr/local/lib/python3.8/dist-packages/skbuild/setuptools_wrap.py", line 621, in setup
    _classify_installed_files(cmake_manifest, package_data, package_prefixes,
  File "setup.py", line 340, in _classify_installed_files_override
    raise Exception("Not found: '%s'" % relpath_re)
Exception: Not found: 'python/cv2[^/]*\.cpython\-38\-aarch64\-linux\-gnu\.so'

My cmake-install directory does not have python directory.

ls ./_skbuild/linux-aarch64-3.8/cmake-install/
bin  include  lib  share

I did add "-DPYTHON_DEFAULT_EXECUTABLE=/usr/bin/python3.8" into the cmake_args in `setup.py'.
Any ideas?

Usually the build has failed at earlier step when the Exception: Not found error is thrown (no .so file was generated). Please refer to the README of this repository, the setup.py file has been refactored. Manual builds are now easier to do.
