Error to be eliminated

[ChongJenniferZhang]

Hi, a great work!
However there is an error showing when I try to run your example as follows
_tkinter.TclError: no display name and no $DISPLAY environment variable

What's wrong with my linux ?

Expect for your reply

Hi Jennifer,

Can you please provide a more formal bug report, something like here http://blog.testlio.com/the-ideal-bug-report? We are not using Linux so it is hard for us to think of the problem because we can't reproduce the problem. Where and when does Treeomics fail exactly? Which version are you using? etc.

Thanks,
Hannes

I ran into the same problem. In my case it was an issue with the matplotlib backend and could be solved by creating a file "~/.config/matplotlib/matplotlibrc" containing the line
backend : agg

See here for details
