PyPI package "cosyvoice" is incomplete — cli/, utils/ submodules missing from the wheel

[leecedarf]

Describe the bug

The PyPI package cosyvoice (current latest 0.0.8) cannot be used for inference. It ships only a thin wrapper layer, while the actual CosyVoice model class lives in a submodule
(cosyvoice.cli.cosyvoice) that is not included in the wheel. Any attempt to use the published API fails at import time.

To Reproduce

pip install cosyvoice==0.0.8
python3 -c "from cosyvoice.api import CosyVoiceTTS"

Error

ModuleNotFoundError: No module named 'cosyvoice.utils'

(raised at cosyvoice/api.py line 3: from cosyvoice.utils.file_utils import load_wav)

Environment

• OS: macOS 15 (Apple Silicon) / Linux
• Python: 3.12
• pip: latest

Root cause — what's actually in the wheel

Listing the .py files shipped in cosyvoice-0.0.8-py3-none-any.whl:

cosyvoice/init.py
cosyvoice/api.py
cosyvoice/server.py
cosyvoice/version.py
matcha/init.py
matcha/app.py
matcha/cli.py
matcha/train.py

Files that should be there (referenced by api.py and required to instantiate CosyVoiceTTS):

• cosyvoice/cli/init.py
• cosyvoice/cli/cosyvoice.py ← the actual CosyVoice model class
• cosyvoice/cli/frontend.py
• cosyvoice/cli/model.py
• cosyvoice/utils/init.py + several utils/*.py
• cosyvoice/flow/, cosyvoice/llm/, cosyvoice/transformer/, cosyvoice/hifigan/, cosyvoice/tokenizer/, cosyvoice/dataset/ (all referenced by the YAML model config)
• the proper matcha/models/ subtree (the wheel ships only the top-level training CLI stubs)

Related issue

pip install "git+https://github.com/FunAudioLLM/CosyVoice" no longer works either — the repo's recent commits removed setup.py / pyproject.toml, so pip refuses to build it. So
users who discover the wheel is broken have no fallback path.

Suggested fix (any of these would unblock users)

1. Republish the wheel with the missing submodules included. The full source is on the main branch — just need package_data / MANIFEST.in to cover all subdirs under cosyvoice/.
2. Add a pyproject.toml and re-enable pip install git+https://... so users can fall back to source installs.
3. If the package is no longer maintained, mark it as deprecated on PyPI and redirect users to CosyVoice2 / CosyVoice3 with working wheels.
