Core ML support: AttributeError: `np.issctype` was removed in the NumPy 2.0 release. Use `issubclass(rep, np.generic)` instead.. Did you mean: 'isdtype'?

trying to install the Core ML support on a macbook pro m3

running

./models/generate-coreml-model.sh base.en

fixes for me was:

• python 3.10 (it is written "recommended" I guess it's "required")
• downgrade numpy pip install numpy\<2

Maybe you should have a requirements.txt ?

Fwiw the following got me going when I hit the same suite of problems:

# (brew install uv)
uv venv --python python3.10
source .venv/bin/activate
uv pip install ane-transformers openai-whisper coremltools==6.3.0 'numpy<2'
# (./models/generate-coreml-model.sh etc.)
