Bug: Error when reading file with librosa, audioread reports `float division by zero` error

Hello!

I was using the following piece of code,

audio, sample_rate = librosa.load(file_name, res_type='kaiser_fast')

But I was thrown the following error,

--> 103     audio, sample_rate = librosa.load(file_name, res_type='kaiser_fast')
    104     mfccs = librosa.feature.mfcc(y=audio, sr=sample_rate, n_mfcc=40)
    105     mfccs_processed = np.mean(mfccs.T,axis=0)

/opt/conda/lib/python3.7/site-packages/librosa/core/audio.py in load(path, sr, mono, offset, duration, dtype, res_type)
    170 
    171     if sr is not None:
--> 172         y = resample(y, sr_native, sr, res_type=res_type)
    173 
    174     else:

/opt/conda/lib/python3.7/site-packages/librosa/core/audio.py in resample(y, orig_sr, target_sr, res_type, fix, scale, **kwargs)
    551         return y
    552 
--> 553     ratio = float(target_sr) / orig_sr
    554 
    555     n_samples = int(np.ceil(y.shape[-1] * ratio))

ZeroDivisionError: float division by zero

I was trying to load a .mp3 using librosa, while using audioread as a backend. I am not sure why the error is ocuring, but I’ll use a try - catch block to avoid it. A similar issue is here, https://github.com/librosa/librosa/issues/765, but the solution to the problem by the author has not been stated.

Help would be appreciated. Thank you!

Hi! It looks like this error happens in librosa code, not in audioread code. So I’m not sure we can do anything about it… do you have more information that indicates that something is wrong in audioread itself?

@Stapelueberflieger try out ps aux to see where the hardware consumption is going towards. Maybe you might need a lighter version for the device you have.
