wheel build for headless fails on 4.7.0 for Py38

bertsky commented 1 year ago

Expected behaviour

When building manually as per documentation, I expect to get a .whl file which I can then pip install.

(I know I can also install via PyPI on my platform, but I have to build my own wheels.)

Actual behaviour

However, step 5 (pip wheel) fails with a strange error message:

Importing the numpy c-extensions failed. - Try uninstalling and reinstalling numpy. - If you have already done that, then: 1. Check that you expected to use Python2.7 from "/usr/bin/python2.7", and that you have no directories in your PATH or PYTHONPATH that can interfere with the Python and numpy version "1.17.3" you're trying to use. 2. If (1) looks fine, you can open a new issue at https://github.com/numpy/numpy/issues. Please include details on: - how you installed Python - how you installed numpy - your operating system - whether or not you have multiple versions of Python installed - if you built from source, your compiler versions and ideally a build log - If you're working with a numpy git repository, try `git clean -xdf` (removes all files not under version control) and rebuild numpy.

(Note: I had to cut off several long passages due to GH's 64k char size constraint, each marked as ....)

I can only see two potential problems:

it seems like it's trying to use python2.7 at times (see Traceback and distutils-precedence.)
it complains Built wheel for opencv-python-headless is invalid: Metadata 1.2 mandates PEP 440 version, but '4.7.0.6b73d90' is not

However, 1. seems to be ignored and later OpenCV gets built and the Python wheels (temporarily), too.

And regarding 2., this is only a warning message. (And I don't see why I must conform to that naming scheme for a local distribution. Furthermore, at least for the CI build, it seems ok to build from a non-tagged commit, as this successful CI log for the same commit shows.)

Steps to reproduce

I followed the instructions for manual builds, except that in my case opencv-python is a submodule, so it's git submodule update --init --recursive opencv-python instead of git clone --recursive https://github.com/opencv/opencv-python.git.

output of git clone

Commands to build:

python3 -m venv /test/venv
. /test/venv/bin/activate && pip install --upgrade pip setuptools wheel
. /test/venv/bin/activate && ENABLE_HEADLESS=1 pip wheel ./opencv-python --verbose

My environment is:

Ubuntu 20.04 distribution of GNU/Linux 5.4.0 on x86_64
Python 3.8.10 / Pip 23.1
opencv-python 6b73d90fc3e50ba6858926d299b49f0228e19d68 (current head of 4.x)

Issue submission checklist

[x] This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
[x] 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)
[x] 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")
[x] I'm using the latest version of opencv-python

bertsky commented 1 year ago

Update: found a thread on the OpenCV forum about this exact problem. The OP there was indeed able to get it done by downgrading to a tagged commit.

So I tried that with f9de34ec8bc8bc5d61e5e35c0721676993da7d71 (which is tagged 72 on 4.x), but then I get another error:

So this time it did not even build OpenCV properly, failing to compile against Numpy.

So this time it did not even build OpenCV properly, failing to compile against Numpy.

Looking more closely at this, it's probably independent – let me know if I should spawn a new issue.

EDIT: So this secondary problem could be a duplicate of https://github.com/opencv/opencv-python/issues/713.

It seems there's a conflict for Python 3.8 between the numpy version requirements featured by

pyproject.toml's build-system.requires: https://github.com/opencv/opencv-python/blob/6b73d90fc3e50ba6858926d299b49f0228e19d68/pyproject.toml#L7
setup.py's install_requires: https://github.com/opencv/opencv-python/blob/6b73d90fc3e50ba6858926d299b49f0228e19d68/setup.py#L29

As the log shows, ~~the latter ultimately gets traction with v1.24.3~~. (However, changing install_requires to an exact version ==1.17.3, I still get the same OpenCV compiler error.)

EDIT: Actually, the log shows that within the skbuild, 1.17.3 was used. And if I instead replace the build-time requirement to the range >=1.17.3 (and remove the _skbuild directory), then pip wheel does succeed.

So to sum up,

the original issue is about the possibility to build via pip wheel from an untagged commit
the second and third post are about a bug in the build-time requirements for Python 3.8, which is a duplicate

And I don't see why I must conform to that naming scheme for a local distribution. Furthermore, at least for the CI build, it seems ok to build from a non-tagged commit, as this successful CI log for the same commit shows.

Ah, I think that works because CI build (scripts/build.sh) uses ENABLE_ROLLING=1, which appends the date in ISO 8601 basic format instead of the git commit hash. So the additional version segment will be fully numerical, which conforms to PEP 440.

In contrast, the commit hash does not. So I wonder why the actual implementation … https://github.com/opencv/opencv-python/blob/6b73d90fc3e50ba6858926d299b49f0228e19d68/find_version.py#L68 … deviates from the documentation (stating that local version identifiers will be used, i.e. concatenation by +) … https://github.com/opencv/opencv-python/blob/6b73d90fc3e50ba6858926d299b49f0228e19d68/README.md?plain=1#L205

The separator used to be a +, but for some reason, it was changed to a . in this commit: https://github.com/opencv/opencv-python/commit/615f3dff836d820398105b82b6ada39d0155cbdc

Indeed. Since this was concerned with setting up rolling releases, it looks like the separator change came by accident.

See https://github.com/opencv/opencv-python/pull/837 addressing both problems.
