No module named 'cv_version'

Expected behaviour

I'm trying to import OpenCV-python to pkgsrc and I'm using python 3.6. When I tried to install the pkg it breaks. I would I appreciate any help to fix this. also, I have all depends install.

Actual behaviour

===> Configuring for py36-opencv-3.4.0.12
=> Fixing locale directory references.
=> Checking for portability problems in extracted files

Local builds are not yet supported. That's why you are getting the error. See #43.

[djadk84]

@skvark Ok I understand, Will be waiting for you guys to have this implemented soon if possible.

[djadk84]

Also, I have to mention If I try to install it via pip its only work for python 2.7 with python 3.6 I get the following error:

pip install opencv-python==3.3.1.11
Collecting opencv-python==3.3.1.11
Could not find a version that satisfies the requirement opencv-python==3.3.1.11 (from versions: )
No matching distribution found for opencv-python==3.3.1.11

[skvark]

Your pip is most likely too old. Upgrade it with pip install --upgrade pip.

[djadk84]

I do believe I'm running the last version of pip

$ pip --version
pip 9.0.3 from ~/pkgenv/lib/python3.6/site-packages (python 3.6)

$ pip install --upgrade pip
Requirement already up-to-date: pip in ./pkgenv/lib/python3.6/site-packages

[skvark]

That's odd, it should work. I presume that you are running some GNU/Linux distribution with standard glibc? Have you tried to install it manually? Download the correct wheel file from PyPI (https://pypi.python.org/pypi/opencv-python/3.3.1.11) and run for example pip install opencv_python-3.3.1.11-cp36-cp36m-manylinux1_x86_64.whl

[djadk84]

I'm running centos 7 with pkgsrc. I have also tried to install it locally but it failed

cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)

$ pip install opencv_python-3.3.1.11-cp36-cp36m-manylinux1_x86_64.whl
opencv_python-3.3.1.11-cp36-cp36m-manylinux1_x86_64.whl is not a supported wheel on this platform.

[skvark]

Unfortunately I can't help. This is related to pip and wheel format. Pip checks your platform and compares it to the wheel filename (cp36-cp36m = Python 3.6 and x86_64 = 64-bit Python and manylinux1 = all GNU C Library based Linux distributions). I guess your Python has been built in some non-standard way and is not ABI compatible with cp36m. You can check supported tags with:

import pip
print(pip.pep425tags.get_supported())

It might be that you package manager has other packages for Python 3.6. You could try if they work with the wheels. More information: https://www.python.org/dev/peps/pep-0425/

This is what I got when I run that command

Looking at that output, it appears that CPython was compiled with pymalloc disabled.

@djadk84 How did you install Python 3.6? This is a pretty unusual configuration for Python.

[native-api]

Since the reason is their Python is incompatible with these prebuilt packages, this can be closed. @djadk84 can run <path/to/python> setup.py bdist_wheel to make a custom build for their Python.
