【python】 Anaconda3配置好后，启动jupyter服务异常的解决方法

在服务器Ubuntu16-64bit上安装了Anaconda3，并配置好jupyter参数， 启动时却报错：

Traceback (most recent call last):

    "__main__", mod_spec)

    from prompt_toolkit.shortcuts import create_prompt_application, create_eventloop, create_prompt_layout, create_output
ImportError: cannot import name 'create_prompt_application'

一查资料是由于prompt-toolkit版本过高导致不兼容，解决方案：
pip install prompt-toolkit==1.0.15

Tips: 在使用pip安装源时，可以换成国内高速的清华源以加速下载。
