This is the link that contains the instructions I followed.
https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf2.md

1. I was following the above instructions to install TFOD2 in my arch linux system.
2. Under the Python Package Installation heading I wasn't able to execute the last command alone.
   python -m pip install --use-feature=2020-resolver .
3. It produces the following error.

Usage:
/usr/bin/python -m pip install [options] <requirement specifier> [package-index-options] ...
/usr/bin/python -m pip install [options] -r <requirements file> [package-index-options] ...
/usr/bin/python -m pip install [options] [-e] <vcs project url> ...
/usr/bin/python -m pip install [options] [-e] <local project path> ...
/usr/bin/python -m pip install [options] <archive url/path> ...

option --use-feature: invalid choice: '2020-resolver' (choose from 'fast-deps', 'truststore','no-binary-enable-wheel-cache')

So if you guys, have any idea how to solve this or, if you know the purpose of this command please enlighten me. Thanks.

5. Are you willing to contribute it? (Yes or No)
   Yes, I am willing to contribute. But I am kind of new to raising issues, but I got some decent experience with ML/DL. So if you got some errands please let me know, I would be glad to help.

I kind of found a work around,

python -m pip install --use-feature=fast-deps .

I started to try the alternatives provided by pip itself and found 'fast-deps' works and 'trust-store' doesn't. And I haven't tried 'no-binary-enable-wheel-cache'.
So keep these in mind.
Hope it helps.
