i want install sndfile to successfully install another package (musdb), but when I tried following instructions on https://cloud.google.com/datalab/docs/how-to/adding-libraries

!pip install sndfile

It gives me the following error:

I tried to google around, it either suggested to download via conda, which seems difficult with datalab, or with the following command

sudo apt-get install libsndfile1

which gives me a syntax error in datalab.

I need this library since I am trying to import musdb and after installing, when I try to import, it gives me the following error:

import musdb

any insights are greatly appreciated!

Datalab comes with conda ready to use in Python 2 and 3 environments. This means you should be able to get what you need with the following:

%%bash

conda install -y libsndfile ffmpeg

pip install musdb
