In packaging a Python application using setuptools, I am populating the install_requires list with all the PyPI dependencies of my application. I find myself manually combing through all my sources to find these. Is this the right way to do it? Or can this list be auto-populated somehow?
Dependencies auto discovery for Python setuptools?

From my point of view install_requires should only list the direct dependencies of your project (not the indirect ones, the dependencies of your dependencies). So it often is a relatively short list, that can probably should be curated by hand, the same way you carefully hand-picked your libraries to begin with.
In common scenarios, using tox in combination with a linting tool such as pylint would let you know if some imports can't be resolved, which most likely means that libraries are missing from install_requires.
In the case you already have lots of dependencies but lost track of which ones and didn't keep install_requires up to date, then I believe a tool such as pipreqs or pigar can help (there are probably other similar tools, but that's the ones I stumbled upon while browsing the following similar questions: 1, 2).
