请教各位前辈，小弟在安装python（3.9.4）idle后，在cmd中使用pip安装了numpy、matplotlib等库，并且numpy、dateutil、pyparsing等都可正常调用，但当调用matplotlib时便显示找不到对应模块，曾尝试卸载重新安装、在cmd中执行等方式皆无法解决。其中代码及部分截图如下：
idle shell 报错：

源代码：
import numpy as np
import matplotlib.pyplot as plt
if __name__ == '__main__':
x = np.array([1, 2, 3, 4, 5])
y = np.array([6, 7, 1, 2, 3])
plt.scatter(x=x, y=y)
plt.show()
