I deleted my venv and started again and noticed a few of these were missing

[markbackman]

Looks like audio and google are unused here. Let's remove them.

@markbackman it looks like RTVI accidentally depends on google because a dependency of rtvi is importing a google class definition 🤔

cc @filipi87 does that ring a bell?

[filipi87]

These two classes, LLMSearchOrigin and LLMSearchResponseFrame, are the ones that we have created for the Google Search response, and are inside the Google. But they should be needed only when using the GoogleRTVIObserver.

[filipi87]

Ok, I have just tested, and if use the version from main, it works as expected. This are all the dependencies that we need.
pip install -e "../..[silero, cartesia, daily, openai, deepgram]"

We have released a version where the RTVI was depending on Google, but that has been fixed by Aleix.

[markbackman]

Thanks! Yes, in Pipecat 0.0.57, that dependency will be removed. We're releasing 0.0.57 today; we can update this PR to remove the google dependency then.
