# Explicit Package Dependencies - Complete ✅

## Summary

All Python packages from both virtual environments (`.venv-cuda` and `.venv`) have been explicitly documented and will be installed in their respective Docker containers with exact version pinning.

## What Was Done

### 1. Extracted Package Lists
- Exported complete package list from `.venv-cuda` (CUDA/Python 3.11)
- Exported complete package list from `.venv` (ROCm/Python 3.10)

### 2. Created Requirements Files

**`requirements-soprano.txt`** (35 packages + PyTorch)
- Core dependencies: fastapi, uvicorn, pyzmq, numpy, pydantic
- Audio: sounddevice, pydub
- ML: lmdeploy, transformers, tokenizers, huggingface-hub, safetensors
- Supporting: accelerate, sentencepiece, protobuf, tiktoken, requests, tqdm, PyYAML, etc.
- Additional: einops, peft, scipy

**`requirements-rvc.txt`** (60+ packages)
- Core dependencies: fastapi, uvicorn, pyzmq, numpy, pydantic
- Audio processing: librosa, soundfile, sounddevice, pydub, audioread, resampy, soxr, pyworld, praat-parselmouth, torchcrepe, torchfcpe
- RVC core: fairseq, faiss-cpu, gradio, gradio_client
- ML: lmdeploy, transformers, tokenizers, huggingface-hub, safetensors
- Scientific: scipy, scikit-learn, matplotlib, pandas
- Performance: numba, llvmlite
- Additional: av, pillow, omegaconf, hydra-core, python-dotenv, ray, local-attention

### 3. Updated Dockerfiles

**`Dockerfile.soprano`** changes:
- Added `COPY requirements-soprano.txt /app/`
- Explicitly install PyTorch with CUDA 11.8: `torch==2.7.1+cu118`, `torchvision==0.22.1+cu118`, `torchaudio==2.7.1+cu118`
- Install requirements: `pip install -r requirements-soprano.txt`
- Install soprano from source: `pip install -e '.[lmdeploy]'`

**`Dockerfile.rvc`** changes:
- Added `curl` to system dependencies (for healthcheck)
- Added `COPY requirements-rvc.txt /app/`
- Added `COPY models/ /app/models/`
- Install requirements: `pip install -r requirements-rvc.txt`
- Removed old dual-install approach (requirements.txt + pyzmq separately)

### 4. Created Documentation

**`DOCKER_DEPENDENCIES.md`**
- Complete list of all packages in each container
- Version numbers explicitly listed
- Key differences between containers highlighted
- Installation order documented
- Verification commands provided
- Maintenance procedures outlined

## Key Version Pins

### Soprano Container (CUDA)
```
Python: 3.11.14
pip: 25.3
PyTorch: 2.7.1+cu118
NumPy: 2.4.1
FastAPI: 0.128.0
LMDeploy: 0.11.1
Transformers: 4.57.5
Soprano TTS: 0.1.0 (editable install)
```

### RVC Container (ROCm)
```
Python: 3.10.19 (target, from base image)
pip: 24.0
PyTorch: 2.5.1+rocm6.2 (from base image)
NumPy: 1.23.5
FastAPI: 0.128.0
LMDeploy: 0.11.1
Transformers: 4.57.3
Fairseq: 0.12.2
Librosa: 0.10.2
```

## Critical Differences

1. **Python Version**: 3.11.14 vs 3.10.19
2. **pip Version**: 25.3 vs 24.0
3. **PyTorch Version**: 2.7.1 (CUDA) vs 2.5.1 (ROCm)
4. **NumPy Version**: 2.4.1 vs 1.23.5 (RVC requires older numpy)
5. **Package Count**: ~35 (Soprano) vs ~60 (RVC)

## Benefits

✅ **No Ambiguity**: Every package version explicitly specified
✅ **Reproducible Builds**: Exact versions match working venvs
✅ **Isolated Dependencies**: Each container has only what it needs
✅ **Version Pinning**: No unexpected updates breaking compatibility
✅ **Documentation**: Complete package manifest for troubleshooting
✅ **Maintenance**: Clear reference for future updates

## Files Modified

```
soprano_to_rvc/
├── requirements-soprano.txt        ✅ CREATED (35 packages)
├── requirements-rvc.txt            ✅ CREATED (60+ packages)
├── Dockerfile.soprano              ✅ UPDATED (explicit installs)
├── Dockerfile.rvc                  ✅ UPDATED (explicit installs)
└── DOCKER_DEPENDENCIES.md          ✅ CREATED (documentation)
```

## Next Steps

1. **Build containers**: `./build_docker.sh`
2. **Verify packages**: Check with verification commands in DOCKER_DEPENDENCIES.md
3. **Test functionality**: Ensure performance matches bare metal
4. **Deploy**: `./start_docker.sh`

## Verification Commands

After building, verify installations match expectations:

```bash
# Soprano container
docker exec miku-soprano-tts pip list | grep -E "torch|soprano|lmdeploy|numpy"

# RVC container
docker exec miku-rvc-api pip list | grep -E "torch|fairseq|librosa|numpy"
```

Expected output should match versions in requirements files.

**Status**: All packages explicitly pinned and documented! 🎯

The Docker containers will now install exact package versions from working virtual environments with no ambiguity.
