我需要安装 ipython 并将 pylab 用于我的信号和系统类。
我已经启动并运行了 ipython(python 版本 3.5)。
我无法让 pylab 初始化。
我已经安装了 matplotlib。 当我在终端中键入 ipython --pylab 时，我得到以下信息:
IPython 4.0.3 -- 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.
