Cannot generate CoreML model

[aviaryan]

I am following the instructions given in the README. However, I am not able to generate a CoreML model.

I did the following steps -

conda create -n py310-whisper python=3.10 -y
conda activate py310-whisper
pip install ane_transformers
pip install openai-whisper
pip install coremltools
./models/generate-coreml-model.sh base.en

And this is the error I get -

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.2 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

Since Python dependency versions vary depending on when you run pip install, maybe someone can provide a lock file like a Pipfile.lock file that will always work.

To get this to work I had to do:

pip install "numpy<2"
pip install torch==2.1.0
