Python matplotlib无法导入pylab

我已经在我的电脑上安装了

matplotlib

及其要求

Numpy

和

scipy

，但我在导入

pylab

时收到此错误消息：

据我记忆所及，它以前可以工作，但现在我收到错误消息。我甚至重新安装了它，但没有帮助。我如何修复它？

可能是您缺少：

import matplotlib as mpl

但是，如果不起作用，请重新安装Anacoda发行版，然后确保已安装numpy和scipy

程序的顶部是：

import numpy as np
import scipy
import matplotlib as mpl
import pylab

@MrE为什么matplotlib与PyUnicodeCs2\u asencodeString发生冲突？
