это проблема 7 марта 2019 года, и jupyter-notebook работал нормально до 6 марта 2019 года.

Сегодня он показывает

Не удалось подключиться к серверу ноутбука.быть установленным.Ноутбук продолжит пытаться восстановить соединение.Проверьте сетевое подключение или конфигурацию сервера ноутбука.

Я попытался удалить торнадо, но он показал, что торнадо не был установлен.

Затем я установил торнадо 5.1.1, который прошел хорошо, нопроблема по-прежнему существует.

Мой Ubuntu - 16,04 LTS, а система - процессор Intel® Core ™ i5-4570 @ 3,20 ГГц × 4.

Я выполнил sudo apt-get install update и sudoКоманда обновления apt-get вчера.Теперь я удалил обновления, которые были сделаны накануне, но проблема не устранена.

В окне терминала появляется ошибка:

В моем случае я запустил его. С моей стороны было непонимание: Tensorflow и Jupyter работают в контейнере Docker, и этот контейнер размещен на Tornado 6, что вызывает проблемы. Мне пришлось заменить торнадо версии 6 на Tornado V5.1.1 внутри этого контейнера, а не на обычном рабочем столе (что было моей первой попыткой удивиться, что я вообще не нашел установку Tornado). Я виноват в том, что я новичок в технологии Docker - просто следовал инструкциям по установке и начал понимать фон позже.

pip uninstall tornado == 6.0.1 pip install tornado == 5.1.1
