Leap 15.2 jupyter-qtconsole is not working

Hi all, today I tried to start jupyter-qtconsole on my system but it could not be launched. Package version python-qtconsole-4.7.4-lp152.1.1.src.rpm If I run it in the terminal the following errormessages are occuring: $ jupyter-qtconsole Traceback (most recent call last): I've no idea to solve the problem.
