# chatterbox-tts==0.1.7 hard-pins transformers==5.2.0 and torch==2.6.0, but
# OmniVoice needs transformers>=5.3.0 (HiggsAudioV2) and the transformers ASR
# pipeline calls torchcodec.decoders.AudioDecoder which only exists in
# torchcodec>=0.3, which in turn needs torch>=2.7. Install chatterbox first
# so it pulls in vocos/encodec/librosa/etc., then force-upgrade transformers,
# torch, and torchaudio above their pins with --no-deps. chatterbox uses
# stable PyTorch APIs and runs fine on torch 2.7 in practice; pip will print
# a "broken requirement" warning that's safe to ignore here.
