Piper TTS will not run on Huggingface

[raivisdejus]

I have an example space on Huggingface with piper-tts as dependency. Starting the space I get error:

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.0 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

Adding requirement for numpy==1.26.4 fixes the issue, but most likely some adjustment to piper-tts dependencies can prevent it in the first place
