升级到jupyter lab 3之后原来的password无法登陆解决方法

1. jupyter-lab 2使用jupyter_notebook_config.py配置文件进行密码设置的操作为：

/opt/pyenvs/envtf22/bin/ipython

Python 3.6.8 (default, Nov 16 2020, 16:55:22)

Type 'copyright', 'credits' or 'license' for more information

IPython 7.16.1 -- An enhanced Interactive Python. Type '?' for help.

In [3]: from notebook.auth import passwd; passwd("heheda")

Out[3]: 'argon2:$argon2id$v=19$m=10240,t=10,p=8$Ktjc9LqcZ7WxFPcjp8SFlQ$oKAMhUstb80LAsEFROzD9A'

vim jupyter_notebook_config.py

# 将 c.NotebookApp.password = 'argon2:$argon2id$v=19$m=10240,t=10,p=8$Ktjc9LqcZ7WxFPcjp8SFlQ$oKAMhUstb80LAsEFROzD9A'
# 加入jupyter_notebook_config.py中

# 启动jupyter-lab

nohup /opt/pyenvs/envtf22/bin/jupyter-lab --config='./jupyter/jupyter_notebook_config.py' &>./jupyter_lab_log.txt &

2. 当升级到jupyter-lab3之后，发现使用原来的jupyter_notebook_config.py配置文件进行启动时会有一些告警，并且使用密码无法登陆，同时又没有token在启动日志中打印。

3. 解决方法

# 将配置文件中使用到的.NotebookApp修改为.ServerApp，如：

# 将 c.NotebookApp.open_browser = False 修改为：

c.ServerApp.open_browser = False

4. 这只能解决告警问题，永久修改密码并保存到配置文件中，还需要继续以下操作：

# shell中输入jupyter-lab password，设置jupyter-lab密码

jupyter-lab password

image

cat /root/.jupyter/jupyter_server_config.json

{

  "ServerApp": {

    "password": "sha1:7f28388e8a7b:ebc342bc6d7eefed08912d7edf6d364751c97c41"

  }

}

将 c.ServerApp.password = "sha1:7f28388e8a7b:ebc342bc6d7eefed08912d7edf6d364751c97c41"
替换jupyter_notebook_config.py中原来的密码配置。

5. 启动jupyter-lab3

nohup /opt/pyenvs/envtf22/bin/jupyter-lab --config='./jupyter/jupyter_notebook_config.py' &>./jupyter_lab_log.txt &

6. 查看启动日志

tail -100 ./jupyter_lab_log.txt
