Ipython: AttributeError: объект типа «IOLoop» не имеет атрибута «текущий»

Я пытаюсь запустить ipython notebook на удаленном сервере в виртуальной среде, но получаю следующую ошибку:

$ ipython notebook -no-browser --port=8000 --ip=0.0.0.0 --log-level=DEBUG

If you suspect this is an IPython bug, please report it at:
    https://github.com/ipython/ipython/issues
or send an email to the mailing list at [email protected]

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
    c.Application.verbose_crash=True

Я прочитал # 7689 и обновил соответствующие пакеты, но пока безуспешно. В отличие от этой проблемы, в моем случае мне не нужно/не нужно ipython-sql

Это вывод pip freeze (список был слишком длинным, поэтому я оставил то, что, как я полагаю, было интересным, но дайте мне знать, если вам нужна дополнительная информация):
