Error while trying to run

[egigoka]

When trying to run:

from kittentts import KittenTTS
m = KittenTTS("KittenML/kitten-tts-nano-0.1")

audio = m.generate("This high quality TTS model works without a GPU", voice='expr-voice-2-f' )

# available_voices : [  'expr-voice-2-m', 'expr-voice-2-f', 'expr-voice-3-m', 'expr-voice-3-f',  'expr-voice-4-m', 'expr-voice-4-f', 'expr-voice-5-m', 'expr-voice-5-f' ]

# Save the audio
import soundfile as sf
sf.write('output.wav', audio, 24000)

I get this error

environment:

• MacBook Air (M1, 2020)
• macOS Sequoia 15.5 arm64
• Python 3.12.11 from Homebrew
• kittentts installed by python3.12 -m pip install https://github.com/KittenML/KittenTTS/releases/download/0.1/kittentts-0.1.0-py3-none-any.whl

If you open up /opt/homebrew/lib/python3.12/site-packages/pydantic/v1/typing.py approximately around line 61 you should see this:

elif sys.version_info < (3, 12, 4):

    def evaluate_forwardref(type_: ForwardRef, globalns: Any, localns: Any) -> Any:
        # Even though it is the right signature for python 3.9, mypy complains with
        # `error: Too many arguments for "_evaluate" of "ForwardRef"` hence the cast...
        # Python 3.13/3.12.4+ made `recursive_guard` a kwarg, so name it explicitly to avoid:
        # TypeError: ForwardRef._evaluate() missing 1 required keyword-only argument: 'recursive_guard'
        return cast(Any, type_)._evaluate(globalns, localns, recursive_guard=set())

Given that your traceback shows the line of code without the recursive_guard kwarg, I would assume that your pydantic needs to be updated to a newer version.

I've tested kittentts on an M1 mac and it works fine. I used a venv and installed kittentts from the repo instead of the wheel. If you are intending to run your scripts from within the kittentts dir, you don't even need to pip install it!

mkdir -p ~/ai/voice
cd ~/ai/voice
git clone https://github.com/KittenML/KittenTTS
cd KittenTTS

python3.12 -m venv .venv
. .venv/bin/activate
pip install -r requirements.txt
pip install .

# vim generate_test.py
python generate_test.py

This would be fixed by #25 – Misaki (which pulls in Spacy, which pulls in Pydantic, where you end up having this issue) is not really needed by the repo.

I used a venv and installed kittentts from the repo instead of the wheel.

As I understand, installing with pip is the main method in README.md
