# Install a dedicated MeloTTS (Korean voice) venv at /opt/melo.
|
|
#
|
|
# Why a SEPARATE venv (not the brain-bridge /opt/venv):
|
|
# - MeloTTS pins old deps (transformers 4.27.4 / tokenizers 0.13.3 / fugashi)
|
|
# whose binary wheels exist only for cp311, so we use python3.11 here even
|
|
# though the image's default interpreter is 3.12.
|
|
# - It isolates the heavy torch/transformers stack from the slim bridge env,
|
|
# which pins numpy<2 for faster-whisper.
|
|
#
|
|
# torch is the CUDA (cu128) build so MeloTTS runs on the GPU alongside Ollama +
|
|
# Whisper. CPU synth serialised under concurrent load (whisper STT + bot) and
|
|
# blew TTS up to 7-8s per reply; on the GPU a sentence synthesises in ~0.3s.
|
|
# cu128 is the Blackwell (sm_120) wheel verified on this host's RTX 5050.
|
|
# The worker selects the device via MELO_DEVICE=cuda (compose).
