Can't tell which file pipreqs is getting its packages from

[melyux]

I have a large project and pipreqs seems to be generating too many packages. I want to know which Python file is resulting in which packages to be found by pipreqs. I tried doing file by file, but apparently pipreqs doesn't support a single file for input either, just entire directories.

There should be a way to see which exact Python file yielded which required packages.
