这是我拥有的python版本：Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:30:26) [MSC v.1500 64 bit (AMD64)] on win32
我安装了ipython的virtualenv环境“ gl-env64”。
我可以在下面的示例中使用ipython：
(gl-env64) C:\Users\Merememories>ipython
Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:30:26) [MSC v.1500 64 bit

In [1]: print 'hi'
hi
In [2]: exit()
但是，当我要使用jupyter notebook时，它将不会加载任何内核，并且会在cmd上输出错误。 在这里：
(gl-env64) C:\Users\Merememories>jupyter notebook
