我在Windows 8中使用Emacs 24.3。使用PowerShell，ipython无问题地加载pylab：
PS C:\Users\vince.forgetta> ipython --pylab
Python 3.4.0 (v3.4.0:04f714765c13, Mar 16 2014, 19:25:23) [MSC v.1600 64 bit (AMD64)]
Type "copyright", "credits" or "license" for more information.
IPython 2.2.0 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object', use 'object??' for extra details.
Using matplotlib backend: TkAgg
In [1]: linspace
Out[1]: <function numpy.core.function_base.linspace>
In [2]: plot
Out[2]: <function matplotlib.pyplot.plot>
但是，使用Emacs 24.3我收到以下错误：

可以通过导入pylab解决：
In [6]: from pylab import *
In [7]: linspace
Out[7]: <function numpy.core.function_base.linspace>
我的.emacs中的Python特定代码是：
;; Python
(setenv "PYTHONUNBUFFERED" "x")
; python-mode
(setq py-install-directory "~/.emacs.d/python-mode.el-6.1.3")
(add-to-list 'load-path py-install-directory)
(require 'python-mode)
; use IPython
(setq-default py-shell-name "ipython")
(setq-default py-which-bufname "IPython")
;; use the wx backend, for both mayavi and matplotlib
(setq py-python-command-args
'("--gui=wx" "--pylab=wx" "--colors=Linux"))
(setq py-force-py-shell-name-p t)
; switch to the interpreter after executing code
(setq py-shell-switch-buffers-on-execute-p t)
(setq py-switch-buffers-on-execute-p t)
; don't split windows
(setq py-split-windows-on-execute-p nil)
; try to automagically figure out indentation
(setq py-smart-indentation t)
从pylab开始使用ipython选项时，--pylab会被导入，但很明显，这似乎并不像我预期的那样有效，或者在那里在某处是一个错误。缓冲区消息不会报告任何错误。
如何在启动pylab缓冲区时自动加载ipython？
感谢。
