# Can't find module lie_algebras

Hi,

I am new to Sage and have been trying the Sage Notebook. I have been trying to run some of the example code from the lie_algebra class. But trying

"import sage.algebras.lie_algebras"

gives me

"ImportError: No module named lie_algebras".

I am trying to use the LieAlgebra module.

Cheers

It is unexpected. How did you install Sage ? Could you please give us some informations so that someone can try to reproduce your problem:

In the title of the question the

`b`

and`e`

in`algebra`

are switched; you didn't do the same mistake when coding by any chance?Thanks. No, it doesn't seem that way. I just typed the title of the question in a hurry. I am running Sage Notebook on a local host and it is supposed to be version 7.5.1. Might I need a rebuild?

I am running Ubuntu 18.04 and here is a screenshot https://drive.google.com/file/d/1SV64jjAl3g6HQgg1-nKL94Nn1yTMXwjM/view?usp=sharing (link_text). I installed Sage from the Ubuntu Gnome software center which says that it is a pre-built binary for Ubuntu 14.04 (Sage ver. 7.5.1~aimsppa6).

I guess I just wanted to know if this was a known previous issue.
