此函数在关键字args之前引入两个args:

This function takes in two args before the keyword args:

scatter(x, y, s=20, ...)

并且您传入了三个，因此您指定了 s 两次(一次隐式，一次显式).

And you are passing in three, so you are specifying s twice (once implicitly and once explicitly).

实际上，我认为您正在尝试使用 2D 散点图函数而不是 3D 散点图函数.您可能想要这样做:

Actually, I think you are trying to use the 2D scatter plot function instead of a 3D one. You probably want to do this instead:

from mpl_toolkits.mplot3d import Axes3D
Axes3D.scatter( ... )
