Hey there @Gidodo!

What version of QIIME 2 are you running?

A nice summary of why you are seeing that error can be found here:

Feature table summarize Invalid DISPLAY variable

Hi @mc92! matplotlib isn’t a QIIME 2 plugin so it won’t show up in qiime info. matplotlib is a Python library for producing plots, and several QIIME 2 plugins use it internally for plotting. Since you’re getting an Invalid DISPLAY variable error from matplotlib, that means it is installed! There’s a few posts on the forum describing how to fix this particular issue. Can you try the suggestions in this post?

QIIME 2 has been shipping with config to prevent that issue from happening, but it sounds like one of the following is impacting you:

• you are running a super old version of qiime
• your execution environment is preventing our config from being applied
• your execution environment is overriding our config

When you run echo $MPLBACKEND what do you see? If it doesn't say agg or Agg, you could try running the following:

echo "backend: Agg" > ~/.config/matplotlib/matplotlibrc 

If it does say agg or Agg, I think you will need to talk to your sysadmin and learn more about the execution environment's configuration.

Hope that helps!
