Hello, When I try to import a python package, I get this error : "ImportError: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found". Then I tried to follow the solution on the Internet, using the command: "strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX", and I found that the latest version seems to be GLIBCXX_3.4.21. But the next step can't go on. How can I fix this problem? Thank you very much in advance.
