FYI: The setup script uses yaml file to list the environment.

https://github.com/pytorch/text/blob/main/.circleci/unittest/linux/scripts/setup_env.sh#L39
https://github.com/pytorch/text/blob/main/.circleci/unittest/linux/scripts/environment.yml

This seems like a clean way to install the same set of packages, but it was disaster for macOS conda environments so audio stopped doing it. (Always getting UnsatisfiableDependencies error)
You might encounter the same situation.

I see so what was the workaround that you use in torchaudio to resolve this?

Manually listing them.

I wonder why YAML approach wouldn't work the same way... Maybe we had mis understanding of the situation. Because even with this approach, macOS conda dependencies are broken most of the time.

Looks good. I see green light on macOS tests, but just to be sure skim through the test log to see if there is any abnormality that are suppressed.

Thanks @mthrok for the review and help in adding the tests. I just looked through the MacOS test logs and everything looked okay. Will merge this once all the CI jobs pass
