Pandas version advanced starting in Jan 2021: numpy is now incompatible

[native-api]

Can't deploy to PyPI anymore: pkg_resources.ContextualVersionConflict: importlib-metadata 0.18

@rmk135 Pip problem. It doesn’t properly update a dependency when it’s installed but some of the other packages requires a newer version. Apart from --upgrade-strategy eager, using the new resolver may help (with --use-feature=2020-resolver or by using Pip 20.3+).
