Running on Pi CM4, pip install fails: Cannot install piper-tts==1.1.0 and piper-tts==1.2.0 because these package versions have conflicting dependencies

Hello, how can i fix this:

 pip install piper-tts

ERROR: Cannot install piper-tts==1.1.0 and piper-tts==1.2.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    piper-tts 1.2.0 depends on onnxruntime<2 and >=1.11.0
    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 attempt to solve the dependency conflict

From the instalation instructions it says i could download the "arm64 (64-bit Raspberry Pi 4)" binary but how do i then install that download?

Thanks!

I installed on a RPI4 8Gb no problem using pip install piper-tts. For the binary you just download them:

wget https://github.com/rhasspy/piper/releases/download/v1.2.0/piper_arm64.tar.gz
tar -xvzf piper_arm64.tar.gz

It should work.

It looks like a new version of something is available with python 3.12.x as it seems to install fine on python 3.11 (fresh pyenv installs of each). Interestingly (and I guess it's been a few days since the OP's issue) I get a different conflict. I'm on x86_64 Ubuntu:

FWIW (as I'm unsure how else you'd've gotten that new a version of python otherwise), if you're also using pyenv, you should be able to install piper on the older version of python and then just: alias piper="$PYENV_ROOT/versions/3.11.8/bin/piper"

Thanks @ag4ve . I tried using Python 3.11.8 on a Pi5 and that works and Piper installs successfully, yay, but on a Pi4 (a CM4), which is what I want to use Piper on, it doesn't. I tried with Python 3.11.7 and 3.11.8:

pip install piper-tts

Any news on the

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

would be so nice to get past that problem

[Derjyn]

Still a blocking issue for many environments. The minefield of dependency issues is maddening.

[SpaceCowboy850]

Agreed. pip install piper-tts doesn't work. On python 3.10.14, Windows, if that helps.

[ekcrisp]

I am getting this error on latest Ubuntu (24 lts) and latest python (3.12). I was able to install the package by using pyenv to downgrade to python 3.9. This is something the project maintainers need to prioritize, using the latest software should work on a project that is under active development, or if it doesn't work that needs to be called out in documentation.

on m1 mac pip install piper-phonemize-cross pip install piper-tts --no-deps worked for me https://github.com/rhasspy/piper/issues/395

[lukas2]

on m1 mac pip install piper-phonemize-cross pip install piper-tts --no-deps worked for me #395

👆 this worked for me on Mac, as well. (please note those are two commands, also I had to run pip install onnxruntime)
