我希望install sndfile成功地安装另一个包（musdb），但是当我尝试按照https://cloud.google.com/datalab/docs/how-to/adding-libraries上的说明操作时

!pip install sndfile

它给出了以下错误：

我试着搜索一下，它要么建议通过conda下载，这在datalab中似乎很困难，要么使用下面的命令

sudo apt-get install libsndfile1

这给了我一个数据实验室的语法错误。在

我需要这个库，因为我正在尝试导入musdb，并且在安装之后，当我尝试导入时，它会给出以下错误：

import musdb

Datalab附带了conda，可以在python2和python3环境中使用。这意味着您应该能够通过以下方式获得所需：

%%bash
conda install -y libsndfile ffmpeg
pip install musdb
