Ошибка 500 в Jupyterhub

Я настроил Jupyterhub в качестве официального сайта,

c.JupyterHub.hub_ip = '0.0.0.0'
c.JupyterHub.hub_port = 8888
c.PAMAuthenticator.encoding = 'utf8'
c.LocalAuthenticator.create_system_users = True
c.Authenticator.admin_users = {'arvin'}
c.Spawner.cmd=['jupyterhub-singleuser']
c.JupyterHub.ssl_cert = '/mycert'
c.JupyterHub.ssl_key = '/mykey'

и когда я зашел на страницу пользователя (вошел в систему) и я получил это:

500 : Internal Server Error
Failed to reach your server. Please try again later. Contact admin if the issue persists.
You can try restarting your server from the home page.

Кто-нибудь может дать мне какое-нибудь решение? Я попробовал некоторые, но они, кажется, не просыпаются.

Это мои логи.

Я заметил, что есть некоторая проблема, что спавнер может не быть достигнут, но я действительно понятия не имею, что делать, даже если я прочитал официальные документы.

Если у вас есть записная книжка, используемая до установки концентратора, и там есть папка ~/.jupyter/. Когда вы запускаете программу-концентратор и запускаете однопользовательскую записную книжку, она считывает конфигурации и вызывает некоторые проблемы, так что концентратор никогда не сможет достичь единственного создателя до истечения времени ожидания.

Я думаю, что это ошибка, которая просто конфликтует с конфигурацией ноутбука ~/.jupyter.

Как только вы уберете $HOME/.jupyter, все будет работать нормально.
