TUI information

Python dependencies for linux users

TUI has strict python dependencies. Many linux users have problems displaying guider or slitviewer images because they have the wrong version of one or more packages. Even if TUI is built correctly, running it from the wrong directory might result in a different package being loaded. Since individual linux and python setups can vary widely, the same solution might not work for everyone. But here are some solutions that have worked for some people.

Download a copy of TUI pre-built for linux as of December 2017 at
