barKoder SDK - Python library

Requirements #

Basic requirments #

A 64-bit OS based on Linux, for an x86-64 CPU architecture. As a general guideline Ubuntu 22.04 or newer is recommended. Install commands given below assume a Debian distro is used (but are not limited to).

python3 (version 3.11 or newer; contact us if you need support for older versions)

Most linux distos come with python. If not already present, it can be installed

Install python3 #

                sudo apt-get install python3

Install pip #

You will need openCV and numpy to run the sample app. These can be installed via pip

                sudo apt install python3-pip
//or
sudo dnf install python3-pip
//depending on the linux distribution

Install openCV-python, numpy and other sample app requirements #

With pip installed you should install opencv-python. You will need it to run the sample app

This package has to be installed for the same version of python that will be used. So if you use python3.11 you need to install it for python3.11

                pip install opencv-python
pip install numpy
//to change the name of the running app
pip install setproctitle

Install curl (optional) #

Curl might be needed for licensing, depending on the type of license used. In particular, curl from snap is required (ref https://snapcraft.io/curl). It can be installed with:

sudo apt install snapd

sudo snap install curl

Using a specific python version #

If you need to use a specific python version, i.e. running the sample app like so:

                python3.11 run.py

you may need to install a side-by-side python version, different than the one you have, for example:

                sudo apt-get install python3.11

                sudo dnf install python3.11

and OpenCV for Python should also be available under that version, and can be installed with:

                python3.11 -m pip install opencv-python

if you can't run this command and your system complains that there is no module named pip you need to upgrade your pip by running

                python3.11 -m pip install --upgrade --ignore-installed pip
//ignore-installed is in case your pip was installed by the system package manager

Eventually, when running the sample app (which you can download from our repository) if you get an error like this:

                ImportError: libGL.so.1: cannot open shared object file: No such file or directory

You are probably on a RedHat distribution and you may need to add this:

                sudo yum install mesa-libGL

Finally get our python lib #

barKoder.com repository #

After you've installed all the necessary requirements to run the software, head over to our repository and download the python library.

Unzip the file and you should find a fully working how-to-start app which should be sufficient to get you started.

github repository #

Alternatively, you can simply clone it from GitHub. The repository includes detailed instructions for running the software, so you might find that method convenient as well.
