<s>[INST] What is setup.py? Can anyone please explain, what is setup.py and how can it be configured or used?
 [/INST] setup.py is a python file, which usually tells you that the module/package you are about to install have been packaged and distributed with Distutils, which is the standard for distributing Python Modules.
This allows you to easily install Python packages, often it's enough to write:
python setup.py install

and the module will install itself.
