Python 属性错误：'；numpy.ndarray和#x27；对象没有属性'；获取矩阵&x27；

我正在尝试使用mlpy绘制一个精彩的PCA，而

plt.scatter

的

c

参数导致了一个异常

数据集：

我有以下错误：

Traceback (most recent call last):
  File "/Library/Python/2.7/site-packages/matplotlib/artist.py", line 59, in draw_wrapper
    draw(artist, renderer, *args, **kwargs)

    all_transforms = [t.get_matrix() for t in all_transforms]
AttributeError: 'numpy.ndarray' object has no attribute 'get_matrix'

当我在

plt.scatter

中删除

c=y

时，它会运行，但我有一种颜色，不允许我识别组。

这与这里的代码完全相同：可能需要先清理一下源代码。例如，定义

data=np.zero（shape=（4,4））

，然后立即将其重新定义为

data=np.array（iris）

；很难确定目的是什么。@user3091978您能做一个简单的可复制的示例吗？
