My Ubuntu version as of time of this writing is 16.04.3 (Xenial Xerus). My aim, however, is to build OpenCV so that it could be used in both C++ and Python.įurther in this blog post I am going to summarize my notes on building OpenCV 3 on Ubuntu using conda’s Python 3.6, with further symlinking of the Python extension to other conda environments. Their availability vary by operating systems and Python versions, but they are in general a pretty good reproducible solution when OpenCV is only used in Python. It is worth to mention that there exist pre-built OpenCV 3 binaries in the menpo channel on Anaconda Cloud. It especially shines on Raspberry Pies, where conda’s pre-built binaries get installed way faster than the pip-installed ones. However, in my work I mostly use conda for managing my Python environments. Such a solution worked pretty well for me, both on Linux and macOS. In particular, Adrian creates a dedicated virtualenv environment, installs NumPy in it, and builds the whole thing having this environment activated. was written in Jan 2021 and is out of date.
He provides detailed description of the required steps, as well as motivation for better development practices. To install Matplotlib, open the Anaconda Prompt and type: > conda install. Unfortunately I have already installed Anaconda, which installs python 3. A successful test will result in conda help contents appearing in the terminal. Earlier you can install OpenCV 2 using formula name opencv and OpenCV 3 using.
Since Miniconda has not been added to your systems PATH environment variable, you will first need to activate conda for this session by calling the activate command by its full system path.

When it comes to building and installing OpenCV with Python support on *nix platforms, the collection of tutorials by Adrian Rosebrock is the best. Print the conda commands help menu to test the Miniconda install. Module 3 - How to Build an Automator Tool to Reduce Content Development Time.
