Spyder требует jedi>=0.10, но устанавливает jedi==0.90

(Работа в Ubuntu 17.04, не знаю, если это что-то изменит) Афер столкнулся с этой проблемой в pip3: https://github.com/pypa/pip/issues/4216 Я прибег к использованию версии dev 10.0.0. Затем, после обновления всех пакетов - я вижу, что не могу открыть spyder, потому что для этого требуется jedi>= 10.0:

Traceback (most recent call last):

    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.VersionConflict: (jedi 0.9.0 (/usr/local/lib/python3.5/dist-packages), Requirement.parse('jedi>=0.10'))

Затем, если я обновлю jedi до любой версии>= 0.10, Spyder высветит сообщение: You have missing dependencies! jedi =0.9.0: 0.10.2 (NOK) но он открывается, без ipython.

Куда я иду отсюда? Внутренняя консоль в spyder говорит мне:

Traceback (most recent call last):
  File "/usr/local/lib/python3.5/dist-packages/traitlets/traitlets.py", line 528, in get
    value = obj._trait_values[self.name]
KeyError: 'banner'

During handling of the above exception, another exception occurred:

и я не нашел никаких ресурсов, чтобы справиться с этим.
