安装 matplotlib 后仍然没有名为 pylab 的模块 [已解决]

问：

我安装了matplotlib，但收到有关pylab不存在的错误。

from pylab import *

Traceback (most recent call last):
  File "c:\users\arne_\mu_code\test.py", line 1, in <module>
    from pylab import *
ModuleNotFoundError: No module named 'pylab'
>>> 

为了清楚起见，这是安装 Matplotlib 后 Windows 中的 CMD

我错过了什么吗？
