Как и многие, я переустановил Anaconda после обновления до macOS Catalina. Я не «деинсталлировал», а удалил папку (я не опытный пользователь, но случайный пользователь python).

Я выполнил чистую установку Anaconda 3 и обновил Python до Python 3.8. Когда я запускаю ноутбук, я получаю сообщение об ошибке «Ошибка ядра».

Нажав на кнопку «Ошибка ядра», я вижу следующее сообщение:

Но когда я набираю «python» в терминале, я вижу, что установлен python 3.8:

Кто-нибудь может помочь мне лучше понять это? Пока я этим занимаюсь, рискую ли я перепутать эту новую установку anaconda с первоначальной?
