Использование соединителя Python mysql-db

Я наконец смог установить коннектор, как показано ниже:

Как подключиться к базе данных MySQL из Python 3 16.04

Я включил результат установить в конце.

Однако, когда я пытаюсь использовать коннектор в некотором коде python3, он не распознает пакет mysqldb?

import mysqldb as mdb

Ошибка, приведенная в pycharm:

ModuleNotFoundError: No module named 'mysqldb'

Это ошибка, потому что я настроил mysqldb в виртуальной среде?

Результаты установки mysqldb:
