I used this last year, with a relative success. I was asked to fix a Python code written by an intern that was no longer there. The code used external libraries, but did not declare any. I had only a zip of the source code, without any library. pipreqs was able to identify the 22 required libraries. Unfortunately, there was a runtime crash because a library was at the wrong version. So I had to let a real Python developer handle the next steps. BTW, this tool is not a dependency manager. Many sibling comments seem to misunderstand the case and promote unrelated tools.
