Unfortunately this goes beyond A.I. stuff, it has become the state of software development and that's why people started shipping very large packages of everything so that you can have the exactly same environment so you can increase your chances that the code will run as expected. For A.I. stuff I actually don't judge, these scripts are written by people who specialise in other things than software engineering and they simply put together some code to run their algorithms and as a result they are poorly engineered in many aspects.
