Я пытаюсь показать рисунок matplotlib.pyplot на Python 3.10, но не могу. Я знаю об этом вопросе и попробовал их ответы, но все еще безуспешно. The default OS distribution is Ubuntu 24.04 using Python 3.12 as a default.
Here is how I setup the Python 3.10 project venv and installed numpy and matplotlib:
