Option 4 - Headless full package (contains both main modules and contrib/extra modules): pip install opencv-contrib-python-headless (check contrib/extra modules listing from OpenCV documentation)Īll packages contain Haar cascade files.

Option 3 - Headless main modules package: pip install opencv-python-headless.

or you are using some other package (such as PyQt) than OpenCV to create your GUI. You should always use these packages if you do not use cv2.imshow et al.

This means that the packages avoid a heavy dependency chain to X11 libraries and you will have for example smaller Docker images as a result. These packages are smaller than the two other packages above because they do not contain any GUI functionality (not compiled with Qt / other GUI components). Packages for server (headless) environments (such as Docker, cloud environments etc.), no GUI library dependencies

Option 2 - Full package (contains both main modules and contrib/extra modules): pip install opencv-contrib-python (check contrib/extra modules listing from OpenCV documentation)ī.

Option 1 - Main modules package: pip install opencv-python.

Packages for standard desktop environments (Windows, macOS, almost any GNU/Linux distribution) If you installed multiple different packages in the same environment, uninstall them all with pip uninstall and reinstall only one package.Ī. There is no plugin architecture: all the packages use the same namespace ( cv2). Do not install multiple different packages in the same environment. There are four different packages (see options 1, 2, 3 and 4 below) and you should SELECT ONLY ONE OF THEM. Select the correct package for your environment: For example Linux distributions ship usually with very old pip versions which cause a lot of unexpected problems especially with the manylinux format. Make sure that your pip version is up-to-date (19.3 is the minimum supported version): pip install -upgrade pip. cv2 module in the root of Python's site-packages), remove it before installation to avoid conflicts. If you have previous/other manually installed (= not installed via pip) version of OpenCV installed (e.g.

This simply plays the mp3 file with an external player.Pre-built CPU-only OpenCV packages for Python.Ĭheck the manual build section if you wish to compile the bindings from source to enable additional modules such as CUDA. This requires you to have some kind of audio player installed on the terminal. You can also play sounds natively on your system. The module doesn’t seem to have been updated in a while. That means that to play sound with this module, you’d also have to import the gui module Tkinter. For old versions there’s ‘python-tksnack’. You can install it with your package manager: ‘apt install python3-tksnack’. The module snack sound kit can play several audio files: WAV, AU, AIFF, MP3, CSL, SD, SMP, and NIST/Sphere. This module can use PyAudio and ffmpeg underneath. It’s available in the pypi repository (install with pip). You can play sound files with the pydub module. This should work with both WAV and MP3 files. It uses windll.winm on Windows, AppKit.NSSound on Apple OS X and GStreamer on Linux. Implementation is different on platforms. This doesn’t have any dependencies, simply install with pip in your virtualenv and run! 1 The playsound module is a cross platform module that can play audio files.

The main difference is in the ease of use and supported file formats. These solutions are cross platform (Windows, Mac, Linux). There are several modules that can play a sound file (.wav).
