Есть несложный проект на Python 3.9 с использованием PyQt5 и matplotlib.
Если я запускаю его на Windows 10 в MS Visual Code, то он открывается и корректно работает.
Но если я пакую этот проект в контейнер Docker, то при запуске контейнера возникает следующая ошибка:
ImportError: Cannot load backend 'Qt5Agg' which requires the 'qt' interactive framework, as 'headless' is currently running
Первые строки кода:
import sys
import matplotlib
matplotlib.use("Qt5Agg")
Как тут быть?
Dockerfile прилагаю, он был создан автоматически через docker init.
