NoBackendError

[Xiaoyong Zhu]

Just want to raise this issue in case someone also encountered this (and share my solution). I will get this no backend error:

Traceback (most recent call last):
  File "CNNClassifier.py", line 54, in <module>
    features,labels = extract_features(parent_dir,sub_dirs)
  File "CNNClassifier.py", line 25, in extract_features
    sound_clip,s = librosa.load(fn)
  File "/datadrive/xiaoyzhu/python2env/local/lib/python2.7/site-packages/librosa/core/audio.py", line 107, in load
    with audioread.audio_open(os.path.realpath(path)) as input_file:
  File "/datadrive/xiaoyzhu/python2env/local/lib/python2.7/site-packages/audioread/__init__.py", line 116, in audio_open
    raise NoBackendError()

In Ubuntu, I use
sudo apt-get install libav-tools

and this issue get solved.
