We need CMake to configure the installation, GCC for compilation, Python-devel and Numpy for building Python bindings etc. You can skip optional dependencies if you don't want. Building OpenCV from sourceĬompiling from source may seem a little complicated at first, but once you succeeded in it, there is nothing complicated.įirst we will install some dependencies. Also at some point in time, if you want to contribute to OpenCV, you will need this. Some major, very- and incompatibly-different versions get their own packages. But with some software (among which is Python) the situation is somewhat different. So for getting latest source codes preference is next method, i.e. Use the apt package manager to install Python. As others already noted, bare sudo apt-get install package will install latest available version, replacing the older one if needed. With respect to Python API, latest version will always contain much better support and latest bug fixes. For example, at the time of writing this tutorial, apt repository contains 2.4.8 while latest OpenCV version is 3.x. Apt repositories may not contain the latest version of OpenCV always. If the results are printed out without any errors, congratulations !!! You have installed OpenCV-Python successfully.
