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. Since Python 2 is in maintenance mode, and Python 3 is recommended by upstream for development, you probably do not need to install the documentation. See the installer README for more information. Note Attention macOS users: As of 2.7.16, all current macOS installers ship with builtin copies of OpenSSL and Tcl/Tk 8.6. 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. Python 2.7.16 Release Date: MaPython 2.7.16 is a bugfix release in the Python 2.7 series. Also at some point in time, if you want to contribute to OpenCV, you will need this.
So for getting latest source codes preference is next method, i.e. With respect to Python API, latest version will always contain much better support and latest bug fixes. You can verify successful installation with this command: python2 -version Python 2.7.18 Step 3. sudo apt update sudo apt install python2 Step 2. Execute the following commands to install it, along with its required dependencies. For example, at the time of writing this tutorial, apt repository contains 2.4.8 while latest OpenCV version is 3.x. Python 2 is available for installation from Ubuntu’s package repositories. 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.
