I met some problem when I install Crazy swarm ROS , I try to run "$CSW_PYTHON -m pytest",
then the result:

I have open another terminal tab and run roscore, but test_ros.py failed,

E ImportError: /home/jaja/anaconda3/lib/python3.7/site-packages/scipy/sparse/../../../../libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by /opt/ros/noetic/lib/libtf2.so)

and I can't solve "libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by /opt/ros/noetic/lib/libtf2.so)"while test.

If you could give me some pointers about this issue it would be greatly helpful
