Hi all, can anyone help me with integrating Nuitrack to a python app?

I am trying to integrate Nuitrack into my app written in python as when I package the app and run it there is an error about initialising Nuitrack (On a different system where there is no Nuitrack installation). I searched online for any documentation, but I could only find integrations for C and C sharp.

# Integrating Nuitrack with your application (Windows/Ubuntu)

In this tutorial, you'll learn how to integrate Nuitrack with your application. We're using `nuitrack_csharp_sample` from the Nuitrack SDK as an example. 

1. Install Nuitrack on your system (see the [Installation Instructions](Install.md)).

2. Create the subfolder `nuitrack` in the application directory `<app_dir>` and copy the following directories from the Nuitrack installation folder to the directory `<app_dir>/nuitrack`:
   * Windows:
     * `%NUITRACK_HOME%\nuitrack\nuitrack\bin`
     * `%NUITRACK_HOME%\nuitrack\nuitrack\data`
     * `%NUITRACK_HOME%\nuitrack\nuitrack\middleware`
   * Linux:
     * `/usr/etc/nuitrack/data`
     * `/usr/etc/nuitrack/middleware`
     * `/usr/local/lib/nuitrack`
	 
   _**Note**: sample application directory:_
     * *Windows:* `C:\Users\<username>\Downloads\NuitrackSDK\Examples\nuitrack_csharp_sample`
     * *Ubuntu:* `~/Downloads/NuitrackSDK/Examples/nuitrack_csharp_sample`

Are there similar steps that I can follow for my python code?

I tried to follow a couple of steps in the C sharp documentation to see if it might work and I get the following error:

nuitrack.init(r"./nuitrack/data/nuitrack.config")

RuntimeError: Nuitrack init failed
WARNING: Cannot load library module: ./nuitrack/middlewareNuitrackModule.dll

Thanks in advance!

Hi @deoxyri,
This tutorial only supports the C++/C# API.
We will update soon, but so far without python support.
If you want to use python for commercial development, write to our support: support-nuitrack@3divi.com
