Many binaries depend on the Microsoft Visual C++ 2010 ( 圆4, x86, for CPython 3.4), or the Visual C++ 2017 ( 圆4 or x86 for CPython 3.5, 3.6, and 3.7) redistributable packages. Note : Open up your command prompt and type following - pip search opencv to ensure whether you python version are We'll cover two approach to have OpenCV 3 for Python 3. cv2 module in the root of Python's site-packages), remove it before installation If you have previous/other manually installed (= not installed via pip) version of OpenCV Python 3.x releases follow Numpy releases.įor example Python 3.3 is no longer supported by Numpy so support for it has been dropped in opencv-python, too.Ĭurrently, builds for following Python versions are provided: Raspbian) and posts for older Python versions just search the web if that doesn't cover you.Python 2.7 is the only supported version in 2.x series. Additionally, PyImageSearch has a very popular number of blog posts on compiling OpenCV from source on macOS and Linux: Ubuntu 16.04, Ubuntu 14.04, macOS, macOS via Homebrew (with an accompanying troubleshooting article), along with a number of other Linux flavors (e.g.

OpenCV has a Python specific tutorial for compiling on Windows and on Fedora. You could compile OpenCV from source if you want to use the newer versions and not have these problems. LGPL licensed build like in the Windows wheels) the goal is considerably harder to achieve. Adding FFmpeg as an additional dependency without a “universal” FFmpeg build (e.g. The purpose of these packages is to provide as easy as possible installation experience for OpenCV Python bindings and they should work directly out-of-the-box. Manylinux and macOS OpenCV binaries are not compiled against it. Q: Why I can’t open video files on GNU/Linux distribution X or on macOS?Ī: OpenCV video I/O depends heavily on FFmpeg. This was a design choice for the package to be more universally installable.įrom the Python Package Index (PyPI) documentation for the opencv-python package: The underlying libraries are not linked in the pip package.

Update => The Pip Packgage on pypi is not linked against FFMPEG for linux:Ĭonda install -c conda-forge opencv provides 3.3 but without contrib However, some functionality of opencv is only given in newer versions or in the contrib version currently not available via conda.ĭoes anyone have an idea why the pip versions won't work? However it will work if and only if I install it fromĬonda install opencv (available opencv 3.1) Pip install opencv-contrib-python (available 3.2,3.3) Pip install opencv-python (available 3.1,3.2,3.3), or I cannot open the webcam if opencv is installed via any of the two: I've been facing a problem with the webcam in opencv in python using anaconda.
