ERROR: Cannot install sunfounder-voice-assistant because these package versions have conflicting dependencies.

The conflict is caused by:
piper-tts 1.2.0 depends on piper-phonemize~=1.1.0
piper-tts 1.1.0 depends on piper-phonemize~=1.0.0

To fix this you could try to:

  1. loosen the range of package versions you’ve specified
  2. remove package versions to allow pip to attempt to solve the dependency conflict

We need time to reproduce and investigate this issue.

For now, it is recommended that you use the Bookworm 64-bit operating system with the desktop environment. Please install all the necessary library files and code, then test to see how it works.

Hi,

I have exactly the same problem. I re-installed using the Bookworm OS, and then all works fine.

Maybe good idea to point this out in the documentation? There are so many variants of Raspbian, I think I tried 3-4 different versions until I found this forum post :slight_smile:
