Question

我想安装sndfile来成功安装另一个软件包（musdb），但是当我尝试按照https://cloud.google.com/datalab/docs/how-to/adding-libraries

上的说明进行操作时

它给我以下错误：

!pip install sndfile

我尝试四处搜索，它建议通过conda下载，这对于datalab或使用以下命令来说似乎很困难

这给我在datalab中的语法错误。

我需要此库，因为我试图导入musdb，并且在安装后，当我尝试导入时，它给我以下错误：

sudo apt-get install libsndfile1

import musdb

OSErrorTraceback (most recent call last)

任何见解都将受到赞赏！

Datalab附带的conda可以在Python 2和3环境中使用。这意味着您应该能够通过以下方式获得所需的东西：

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

无法在datalab中安装声音文件
