我能够在Ubuntu上修复此错误，方法是在将模块目录附加到路径的笔记本顶部添加一个单元格：

I was able to fix this error on Ubuntu by adding a cell to the top of the notebook appending the module directory to the path:

import sys
sys.path.append('/usr/lib/python2.7/dist-packages')

运行 pip install< something> $时，可以找到添加的路径c $ c>，（例如numpy）它会告诉你每个软件包的安装位置或已经存在。

The path to add can be found when running pip install <something>, (such as numpy) and it tells you where each package is installed or already exists.
