You'll need a backend for librosa. See this thread: https://github.com/librosa/librosa/issues/219#issuecomment-120087907

Thank you for reporting that, I believe this is due to your matplotlib version mismatching mine. I have 3.1.1, what is yours (pip freeze | grep matplotlib)?

[marcoippolito]

Solved that problem by installing matplotlib (version 3.1.1) (I discovered it was not installed). But now got new issue:

You still need to install a backend

[CorentinJ]

Good catch, you will either need to put an audio output device or disable the calls to sd.play in demo_utils. I'll fix that later

[CorentinJ]

With cdd51df126dc5304a04ad6b01ca0811575c8809b, you should now be fine. It should only print an error when trying to play the audio but the program should work.

[yunfei-shi]

I solve it by install ffmpeg on ubuntu18.04: sudo apt install ffmpeg.
