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:
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! :qiime2:
