Town Square

Hello experts,

I’m newbie for cvmfs. when I used the environment: /cvmfs/sft.cern.ch/lcg/views/LCG_102/x86_64-centos7-gcc11-opt/setup.sh, I tried to use pyplot inside matplotlib to plot, there is an error: qt.qpa.plugin: Could not find the Qt platform plugin “xcb” in “”.

Could you give me some advice? thanks in advance.

Best regards,
Qiuping
