jupyter 启动时的问题

  用Pip下载jupyter notebook时发现启动时会有两个值得注意的地方,一个是启动时的环境变量参数路径设定,一个是启动后默认的工作区设定。

因为默认只能在 C:/users/用户名 路径下执行jupyter notebook,这样环境变量参数路径和工作区都设在了该目录,怎样修改呢?

  我写了一段python代码 start_jupyter.py ,用来指定启动时的环境变量参数路径:

 1 import os
 2 import subprocess
 3 
 4 base = 'D:\Program Files (x86)\Python\Python36'
 5 jupyter_dir = os.path.join(base, '.jupyter')
 6 
 7 if not os.path.exists(jupyter_dir):
 8     os.mkdir(jupyter_dir)
 9 
10 dirs = {'JUPYTER_CONFIG_DIR': jupyter_dir, 'JUPYTER_RUNTIME_DIR':os.path.join(jupyter_dir,'runtime'), 'JUPYTER_DATA_DIR':os.path.join(jupyter_dir,'data')}
11 
12 for k, v in dirs.items():
13     if not os.path.exists(v):
14         os.mkdir(v)
15     os.environ[k] = v
16 
17 ipython_dir = os.path.join(base,'.ipython')
18 os.environ['IPYTHONDIR'] = ipython_dir
19 
20 subprocess.call(['D:\\Program Files (x86)\\Python\\Python36\\Scripts\\jupyter-notebook.exe'])

   接下来轮到设定工作区,打开 .jupyter/jupyter_notebook_config.py, 修改 c.NotebookApp.notebook_dir =‘’  为实际的工作区地址:

c.NotebookApp.notebook_dir = 'D:\Program Files (x86)\Python\Python36\jupyter_workpath'

这样在jupyter notebook启动时就可以指定工作区, 执行启动命令: python start_jupyter.py
