How to package a python project that has dependency on tflite_runtime?

Question

tflite_runtime is not hosted in pypi, but can be installed as:

pip3 install --extra-index-url https://google-coral.github.io/py-repo/ tflite_runtime

How can I package my project which has this dependency?

I have seen this setuptools docs and some threads 1, 2 but no luck so far.

setup.cfg

[options]
...
dependency_links = https://google-coral.github.io/py-repo/tflite-runtime/
install_requires =
    tflite_runtime==2.5.0

Bonus: locally I use mac. My deployment will be on linux. Is there a way to install the right whl based on OS?

dependency_links were declared obsolete and finally removed in pip 19.0. The replacement for it is install_requires with special syntax (supported since pip 19.1): 'package_name @ git+https://gitlab.com/<user>/<repo>.git@<commit>'. See pip.pypa.io/en/stable/cli/pip_install/#requirement-specifiers and python.org/dev/peps/pep-0440/#direct-references . This requires pip install and doesn't work with python setup.py install. — phd

I suspect dependencies that aren’t in PyPI are not fully supported now. Either you point a direct reference to an exact file (no platform and no version variability) or to a VCS repository. But not to an extra index. — phd

This worked for me to install .whl package and make it OS specific.

setup.py

import setuptools
import platform

# tflite for linux
tflite = "tflite_runtime@https://github.../tflite_runtime-...-cp37m-linux...",

if platform.system() == 'Darwin':
    # tflite for macos
    tflite = "tflite_runtime@https://github../tflite_runtime...cp37m-macosx..."

setuptools.setup(
    include_package_data=True,
    install_requires=[
        tflite,
        ...
    ]

A cleaner approach should be using Environment Markers, but I couldn't get that to work.
