【python】 Anaconda3配置好後，啓動jupyter服務異常的解決方法

在服務器Ubuntu16-64bit上安裝了Anaconda3，並配置好jupyter參數， 啓動時卻報錯：

Traceback (most recent call last):
  File "/root/anaconda3/lib/python3.6/runpy.py", line 193, in _run_module_as_main
    "__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'

一查資料是由於prompt-toolkit版本過高導致不兼容，解決方案：
pip install prompt-toolkit==1.0.15

Tips: 在使用pip安裝源時，可以換成國內高速的清華源以加速下載。
