lets debug the error:
The above is a TypeError: indicating librosa.filter.mel() got 0 positional arguments are given, which indeed aren't needed.
going to audio.py line 100, the arguments are there for a specific purpose like for sampling rate, The number of samples used in each block for the Fourier transform, The number of Mel filters to generate, The lowest frequency (in Hz) of the Mel filters, The highest frequency (in Hz) of the Mel filters.
The below code does which is throwing the error looks something like the below.
def _build_mel_basis(): assert hp.fmax <= hp.sample_rate // 2 return librosa.filters.mel(hp.sample_rate, hp.n_fft, n_mels=hp.num_mels, fmin=hp.fmin, fmax=hp.fmax)
But as far as I can make a sense of it the code is pretty legit and shouldn't be raising an error,
Now navigating through several files and looking through a bunch of code,
what I can guess is the format expected here is 'wav' for audio.
So please look for the audio format that your are using, if the audio is not 'wav' then it needs to be changed.

Thank you for your reply. The problem was solved by lowering the version of librosa, but a new problem appeared. The installation of the lower version of numba failed, and the following interface incompatibility problem occurred with the higher version of numba. how should I solve this?

I think these error's are rising due to incompatibility issues.

- So trying previous builds of python might help, rather than using python 3.10.

If you lower the python version to 3.8, pip cannot be installed, and the example still cannot be run. colab cannot install python3.6.

is there anyway you can try to run it on your local machine.

After reading librosa Doc https://librosa.org/doc/latest/generated/librosa.filters.mel.html
We can change the code in audio.py line 100 to : return librosa.filters.mel(sr=hp.sample_rate, n_fft=hp.n_fft, n_mels=hp.num_mels, fmin=hp.fmin, fmax=hp.fmax)

To all those facing : No module named 'numba.decorators'

set librosa version to 0.9.0. and numba = 0.58.1
