Installation problem - using conda install - missing class 'presets'

[Phillip Glau]

I ran the command

conda install -c conda-forge librosa

But when I try running the gallery examples, I get the error:

>>> from presets import Presets
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

So obviously 'presets' is missing from my install. I double checked that I can import 

import librosa as _librosa
import librosa.display as _display

And they both seem to import fine. 

Can somebody point me in the direction of getting the 'presets' class. 

My first guess didn't work and I don't see it on the GitHub for librosa, but perhaps I missed it.

conda install -c conda-forge presets

Thank you in advance for you help.

The examples in the gallery are not necessarily self-contained.  The `presets` module can be installed by pip:

pip install presets

And everything else should work.

That did the trick. Thanks, Brian.
