[Code health] Remove Re-definition found for builtin function

🚀 Feature

As reported by deepsource in here we abuse from using built-in input function in our functionality.

Motivation

We target to have a clean and healthy source code free of risk.

Pitch

Replace variable names whether it makes sense e.g. for image based functionality input -> image ; in losses input -> pred (or similar)

I do agree with the tool… It is not considered Pythonic to shadow a builtin. It does not matter if the current code does not use input() because a future contributor might add it and then be highly confused by the results.

@sesam I’d go module by module and possibly starting with test files
