Supress "PySoundFile failed. Trying audioread instead." warning

I’m trying to load an mp3 file with librosa.load(path) and it returns the following warning:

>>> import librosa
>>> librosa.load('mysong.mp3')
/data/anaconda3/envs/aidio/lib/python3.7/site-packages/librosa/core/audio.py:146: UserWarning: PySoundFile failed. Trying audioread instead.
  warnings.warn('PySoundFile failed. Trying audioread instead.')
(array([-0.00183699, -0.00195219,  0.00391953, ..., -0.00337326,
        0.00295902,  0.00624093], dtype=float32), 22050)

As I’m doing this multiple times it floods the stdout. So I have some questions:

Why is this a warning? Does it imply something bad?
Can I hide this warning text? As it floods my stdout in my batch operations.

1. Why is this a warning? Does it imply something bad?

It’s a warning, not an error. This warning will always occur when loading mp3 because libsndfile does not (yet/currently) support the mp3 format. Librosa tries to use libsndfile first, and if that fails, it will fall back on the audioread package, which is a bit slower and more brittle, but supports more formats.

2\. Can I hide this warning text? As it floods my stdout in my batch operations.

Yes, you can always filter warnings. https://docs.python.org/3/library/warnings.html

Any idea how to avoid getting this warnings printed on STDOUT?

I tried launching script with python -W ignore <script> and adding:

import warnings
warnings.filterwarnings('ignore')

At the beginning of the scripts and this User Warnings keep poping out.

Edit: Nevermind it was my issue.
