run matplotlib script, waring as,

search the two lib as,

make link as,

/usr/lib/dri$ sudo ln -s /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so swrast_dri.so
then run matplotlib script again, warning as,

cp the proper lib and make link as,
~/miniconda3/envs/xplore_matplotlib/lib$ cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.30 . ~/miniconda3/envs/xplore_matplotlib/lib$ ln -fs libstdc++.so.6.0.30 libstdc++.so ~/miniconda3/envs/xplore_matplotlib/lib$ ln -fs libstdc++.so.6.0.30 libstdc++.so.6
then run matplotlib script again, goes well ...
Over.
