# ============================================================================
# CHATTERBOX TTS SERVER - REQUIREMENTS (CPU-ONLY INSTALLATION)
# ============================================================================
# This file ensures compatible PyTorch, ML, and audio processing libraries
# are installed for CPU-only operation.

# --- PyTorch CPU-Only Installation Index ---
--extra-index-url https://download.pytorch.org/whl/cpu

# --- Deep Learning Framework (CPU-Only) ---
torch==2.5.1
torchvision==0.20.1
torchaudio==2.5.1

# --- Core TTS Application ---
# IMPORTANT: chatterbox-tts is NOT included here. It must be installed
# separately with --no-deps to prevent dependency resolver conflicts
# (ONNX source builds, torch version mismatches).
#
# The start.py launcher handles this automatically.
#
# For manual installation, run these commands in order:
#   pip install -r requirements.txt
#   pip install --no-deps git+https://github.com/devnen/chatterbox-v2.git@master s3tokenizer==0.3.0 onnx==1.16.0

# --- Chatterbox Dependencies (explicit, since --no-deps skips them) ---
# NOTE: s3tokenizer and onnx are installed with --no-deps alongside chatterbox
# to avoid protobuf version conflicts (onnx requires protobuf>=3.20.2 but
# descript-audiotools requires protobuf<3.20).
