We highly recommend setting up a virtual environment before running the run_tester_python.py
script.
The main purpose of a Python virtual environment is to create an isolated environment for Python projects. You can find more infomation here.
Run the following commands from within the python
directory to setup a Python virtual environment:
$ python3 -m pip install --user virtualenv
$ python3 -m venv env
$ source env/bin/activate
$ pip3 install -r requirements.txt
