Issues running in Jupyterhub

[ladymalina]

I cannot seem to get the is to work in the jupyterhub setup. I have installed everything correct but receive a consisted traceback error. this is the error I receive anytime I try to run any type of code in the Notebook.

Traceback (most recent call last):
File "/opt/tljh/user/lib/python3.6/site-packages/powershell_kernel/kernel.py", line 62, in do_execute
self.__createProxy()
File "/opt/tljh/user/lib/python3.6/site-packages/powershell_kernel/kernel.py", line 51, in __createProxy

Any help is greatly appreciated.
