Unable to convert function return value to a Python type! The signature was () -> handle

[NicolasGoeddel]

After creating the conda environment and pip install -r requirements.txt I get this:

$ python transcribe.py --f ~/Interview.m4a

2025-10-01 13:44:28.247276: I tensorflow/core/platform/cpu_feature_guard.cc:182] This TensorFlow binary is optimized to use available CPU instructions in performance-critical operations.
To enable the following instructions: AVX2 FMA, in other operations, rebuild TensorFlow with the appropriate compiler flags.

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.2.6 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.

The above exception was the direct cause of the following exception:

I don't think I did something wrong here. Why does it happen?
