Nbextensions

Jupyter notebook改变默认的工作目录

查看配置文件位置
jupyter notebook --generate-config
Writing default config to: C:\Users\jiangshan\.jupyter\jupyter_notebook_config.py
打开jupyter_notebook_config.py找到如下
## The directory to use for notebooks and kernels.
#c.NotebookApp.notebook_dir = ''这一行修改如下：
windows是双斜杠（\\），linux是反斜杠（/）
c.NotebookApp.notebook_dir = 'F:\\workspace'
