Not able to install packages that rely on Tensorflow on Mac M1

I successfully installed Tensorflow 2.7.0 on my MacBook with an M1 chip following this guide by Apple: https://developer.apple.com/metal/tensorflow-plugin/

I now want to install a package (ethnicolr) in a project that relies on Tensorflow >=1.15.2. This should not be an issue, but it sadly is.

requirements.txt of my project

pandas==1.3.4
ethnicolr==0.4.0

requirements.txt of ethnicolr:

tensorflow>=1.15.2

Running pip install -r requirements.txt yields

ERROR: Could not find a version that satisfies the requirement tensorflow>=1.15.2 (from ethnicolr) (from versions: none) ERROR: No matching distribution found for tensorflow>=1.15.2

Running pip list shows, that Tensorflow was installed. But it's not called tensorflow, but tensorflow-macos or tensorflow-metal.

tensorboard             2.7.0
tensorboard-data-server 0.6.1
tensorboard-plugin-wit  1.8.0
tensorflow-estimator    2.7.0
tensorflow-macos        2.7.0
tensorflow-metal        0.3.0

What is a solution here? There must be more packages out there with the requirement of Tensorflow...
