Hello, Dmitry. I understand that for experienced Python developer it obvious from stack trace I send.
But can we check python version on startup? And print big fat error message "You are using wrong python version". From my experience, there are some tickets in Ignite that should be implemented in various thin clients. It a very trivial changes, but lack of testability makes this task harder then steel. I think a .Net DEVNOTES are very good example. Please, be gentle with your fellow contributors and make DEVNOTES as clear as possible.
