Я использую виртуальную среду с Python 2.7.(Ubuntu 16.04.5 LTS), когда я import matplotlib.pyplot as plt я получаю ошибки ниже.

Думая, что новый pip распознает python-tk, я попытался обновить pip в виртуальной среде,
(venv2) ckim@chan-ubuntu:~/venv2$ sudo pip install --upgrade pip

и я деактивирую среду virutla и устанавливаю в систему python-tk,

python-tk is already the newest version (2.7.12-1~16.04).
0 upgraded, 0 newly installed, 0 to remove and 23 not upgraded.
, поэтому он говорит, что ppython-tk уже установлен.Что я должен делать?Я проверил 'ask ubuntu' или 'stackoverflow', но не смог найти справку, которая мне подходит (пробовал pip install tkinter, но получил сообщение could not find version that satisfies..)
