Я ранее использовал Jupyter Notebook (python 2 и 3) на моем Mac.После того, как я не использовал его некоторое время, кажется, что я не могу решить проблему.При запуске ноутбука из терминала с помощью команды Jupyter notebook, а затем выбора ноутбука, с которым я хочу работать, я получаю сообщение об ошибке:
"A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration."
Я уверен, что это не имеет никакого отношения к моему интернет-соединению(Я пробовал 2 машины, подключенные к разным сетям).
Я прочитал, что проблема в браузере, поэтому я установил Chrome и Firefox.Тем не менее, я получаю эту ошибку, когда я использую Safari, Chrome и Firefox.
Затем я прочитал о проблеме с прокси.Я попытался добавить адрес сервера ноутбука в No proxy fields расширенных сетевых настроек моего Mac и расширенных настроек Firefox.
Единственное, о чем я могу думать, это что я ввел неправильный адрес сервера?
Я не очень разбираюсь в настройках и ошибках в целом, надеюсь, кто-то может предложить мне несколько альтернативных вариантов, чтобы заставить Jupyter работать снова.
