我想试一下用spyder画图的功能，输入了如下代码：
import matplotlib.pyplot as plt
plt.scatter(2,4)
plt.show()
点F5执行后出现如下内容。我有几个问题：
1.出现的错误是最后面的AttributeError: 'module' object has no attribute 'to_rgba'吗？这是什么错误呢该如何改正呢?
2.为什么在AttributeError: 'module' object has no attribute 'to_rgba'上面还出现了其他的文件也指出了某行的某些内容，它们也有错误吗？这些问题是同属于AttributeError: 'module' object has no attribute 'to_rgba'的错误吗？
希望大家能帮我看看，急需，感激不尽！！
