Итак, я попытался исправить свой блокнот Jupyter (он не позволял мне импортировать библиотеки), однако, похоже, я сделал что-то хуже. Теперь, когда я запускаю ноутбук, ядро запускается, а затем мгновенно умирает. Ошибка, которую я получаю, ниже:

Есть ли способ исправить это? Или мне нужно просто полностью удалить и переустановить? Кроме того, как мне это сделать? Когда я делаю sudo pip uninstall jupyter, он не работает.
