I’ll simply say that you should use whichever version of Python you are comfortable with and use on a daily basis. Regarding which Python version you should use… I’m not getting into that argument. Make sure you are consistent with your decision, otherwise you will inevitably run into compile, linking, and import errors. I’ve highlighted the steps that require you to make a decision regarding which version of Python you would like to use. In either case, this tutorial will support both Python 2.7 and Python 3. There are plans to migrate to Python 3 and use Python 3 by default however, as far as I can tell, we are still a long way from that actually becoming a reality. Python 3.5.2 (can be accessed via the python3 command).Īgain, it’s worth repeating that Python 2.7 is still the default Python version used by Ubuntu.Python 2.7.12 (used by default when you type python in your terminal).The actual versions (as of 24 October 2016) are: Ubuntu 16.04: How to install OpenCVīefore we get into this tutorial, I want to mention that Ubuntu 16.04 actually ships out-of-the-box with both Python 2.7 and Python 3.5 installed. From there, just ignore the Python bindings and proceed as usual. Follow along with the instructions and perform the steps - by the end of this article you’ll have OpenCV installed on your system. Note: Don’t care about Python bindings and simply want OpenCV installed on your system (likely for C++ coding)? No worries, this tutorial will still work for you. To learn how to install OpenCV on your Ubuntu 16.04 system, keep reading. Inside this tutorial, I will document, demonstrate, and provide detailed steps to install OpenCV 3 on Ubuntu 16.04 with either Python 2.7 or Python 3.5 bindings.įurthermore, this document has been fully updated from my previous Ubuntu 14.04 tutorials to use the latest, updated packages from the apt-get repository. However, with support of Ubuntu 14.04 winding down and Ubuntu 16.04 set as the next LTS (with support until April 2021), I thought it would be appropriate to create a new, updated Ubuntu + OpenCV install tutorial. Install OpenCV 3.0 and Python 3.4+ on Ubuntu 14.04.Install OpenCV 3.0 and Python 2.7+ on Ubuntu 14.04.
Over the past two years running the PyImageSearch blog, I’ve authored two tutorials detailing the required steps to install OpenCV (with Python bindings) on Ubuntu.
