If you are facing any type of error during the installation of libjasper-dev library, follow the below steps.

Apt get install gfortran install#

Now we have to install the libjasper-dev. These libraries help us to read images from the local drive along with the video. Now we are going to install some image tools and video libraries (input and output). Now we are going to install some tools which will help us while installing OpenCV on Ubuntu.

Apt get install gfortran update#

We are going to update the operating system using the following commands: $ sudo apt-get update Open your Ubuntu laptop or Desktop and then start the terminal either click on the show Application option and then search terminal or else press Ctrl + Alt + T from your keyboard.

Step 1: Installation of the OpenCV dependencyДЇirst, we will start by updating our operating system and making sure all the OpenCV dependencies are installed. To check Python 3 version(and also if it is pre-installed or not) on Ubuntu we have to use the following command: $ python3 -versionДЇigure 1: The above screenshot shows the Python3 version The main thing about this setup guide is that we will be using Python 3.0+ and not Python 2.7 because by default the Ubuntu 18.04 or above supports directly Python 3.0+ and they have completely dropped python 2.7 from the operating system. module use petsc).In this blog, we are going to install OpenCV on Ubuntu 18.04 or above. If multiple versions and dependencies are being used simultaneously,ДЇor example on a cluster, the paradigm of environment modules is often used (e.g. When configuring your environment, the examples shown here set environment variables, $PATH, and $LD_LIBRARY_PATH in. This separation adds a level of complexity but is more extensible if multiple package versions/installations are going to be used.

The build and installation paradigm demonstrated here puts source code, build files, and installed packages all in $HOME/packages.ДЄnother common convention is to use $HOME/src for source code and building, Installing packages system-wide requires root access, which is an increased security risk when downloading packages from the internet.ДЄlso, it is typically easier to uninstall packages or otherwise revert changes made at a local level.ДЇinally, local installations are required when running on a cluster environment. Local installations are generally preferred. The build examples described here are all installed locally (e.g. Python runtests.py Other Methods and Notes пѓЃ If theyвЂ™re not available already, common prerequisites can be installed via apt under Ubuntu:

The supported operating systems are Ubuntu 18.04 and 20.04, together with GNU compiler versions 7 to 9.ДЇor the rest of the instructions, we use angled brackets such as as placeholders, where you should enter values specific to your installation such as package versions.

On the other hand, cluster installs may benefit from the stable versions. If you are doing a clean install, itвЂ™s probably best to use the versions listed under the latest column. Therefore, if you choose to use a different dependency version, then you are essentially on your own. Although the code may work with other dependency versions (for example NumPy and SciPy requirements are not strict), we only test code against the dependency versions listed below.
