1. Install prerequisites. You may also need to install pip. For example, on Ubuntu execute the following command to install Python and pip:

   sudo apt install python3-dev python3-pip
   

   If you already have installed pip before, make sure it is up to date by doing:

   pip install --upgrade pip
   

2. Create a clean virtual environment:

   One of the possible ways for creating a virtual environment is to use virtualenv:

   python -m pip install virtualenv
   python -m virtualenv <directory_for_environment>
   

   Before starting to work inside the virtual environment, it should be activated:

   On Linux and macOS:

   source <directory_for_environment>/bin/activate
   

   On Windows:

   .\<directory_for_environment>\Scripts\activate
   

   Please make sure that the environment contains wheel by calling the following command:

   python -m pip install wheel
   

   NOTE: On Linux and macOS, you may need to type python3 instead of python.

3. Install requirements in the environment:

   python -m pip install -r requirements.txt
   

Make sure to activate your virtual environment

1. Edit inferece_demo.py to specify your media source. Use an index for cameras or supply a path to a video file. Then run!

   python inference_demo.py
   

1. If you use Anaconda as environment manager, please consider that OpenVINO has limited Conda support. It is still possible to use conda to create and activate your python environment, but in that case please use only pip (rather than conda) as a package manager for installing packages in your environment.

2. If you have problems when you try to use the pip install command, please update pip version as per the following command:

   python -m pip install --upgrade pip
