Hi @sltzgs, could you please post a full stacktrace of the exception? It would also help if you could provide a code snippet, for which it occurred, and describe your environment. As for the environment, it could be useful for us to know all the packages you have installed (e.g., pip freeze > requirements_old.txt), your OS and python distributions.
