jupyter安装出现问题：安装后无法打开

traitlets.traitlets.TraitError: Could not decode 'C:Users\xcexa2xccxf0xd0xc4xd3xef.jupyter' for unicode trait 'config_dir' of a NotebookApp instance.

解决办法：将下面一段代码保存为py文件，文件名为“python jupyter_nootbook_start.py”，以后运行该文件即可打开jupyter。

 1 import os
 2 import subprocess
 3 
 4 #base = 'D:\Anaconda'
 5 base = 'D:ProgrammingToolpythonAnaAnaconda'
 6 jupyter_dir = os.path.join(base,'.jupyter')
 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.iteritems():   
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 
19 os.environ['IPYTHONDIR'] = ipython_dir
20 
21 subprocess.call(['D:ProgrammingToolpythonAnaAnacondaScriptsjupyter-notebook.exe'])
