error when running main.py file

[ibatuloff]

So I followed instructions and installed ecoute.
But when I run this command:

python main.py

I get this error:

C:\Users\username\AppData\Local\Programs\Python\Python310\lib\site-packages\whisper\timing.py:58: NumbaDeprecationWarning: The 'nopython' keyword argument was not supplied to the 'numba.jit' decorator. The implicit default value for this argument is currently False, but it will be changed to True in Numba 0.59.0. See https://numba.readthedocs.io/en/stable/reference/deprecation.html#deprecation-of-object-mode-fall-back-behaviour-when-using-jit for details.

ValueError: source code string cannot contain null bytes

Any idea on how to fix this?
