I thought import names and PyPI names are not always equal, thus this can not work reliably, right?

It uses this file which maps import names to package names, but it's only 1152 packages and I'm not sure how it was generated. https://github.com/bndr/pipreqs/blob/master/pipreqs/mapping

In fairness that only seems to list those packages where the import name doesn't match the package name (e.g., it doesn't include numpy) so its overall coverage is a lot larger than that.

Even worse, there are some different PyPI packages with the same import name. For example, `import snappy` is probably referring to the compression library https://pypi.org/project/python-snappy/ but it could be this maths package https://pypi.org/project/snappy/
