如何更新IPython 5.0的PromptManager设置？

Question

线条

# Output prompt. '\#' will be transformed to the prompt number
c.PromptManager.out_template = '{color.Green}Out[{count}]{color.Green} : {color.LightGray}'

# Continuation prompt.
c.PromptManager.in2_template = '{color.Yellow}   .\\D.{color.Green} : {color.LightGray}'

# If True (default), each prompt will be right-aligned with the preceding one.
c.PromptManager.justify = True

# Input prompt.  '\#' will be transformed to the prompt number
c.PromptManager.in_template = '{color.Green}In [{count}]{color.LightGreen} : {color.DarkGray}'

在我的ipython_config.py给予

usr/local/lib/python2.7/site-packages/IPython/core/interactiveshell.py:440: UserWarning: As of IPython 5.0 `PromptManager` config will have no effect and has been replaced by TerminalInteractiveShell.prompts_class
  warn('As of IPython 5.0 `PromptManager` config will have no effect'

但替换PromptManager为TerminalInteractiveShell.prompts_class没有效果.
