python - 我如何解决我的 Birch Clustering PyPlot 错误问题

Question

我对我的数据进行了 Birch 聚类分析。之后，我尝试使用下面的代码来绘制我的分析，然后我得到了这个错误。我该如何解决？谢谢你。

# create scatter plot for samples from each cluster
for cluster in clusters:
# get row indexes for samples with this cluster
    row_ix = where(yhat == cluster)
# create scatter of these samples
    pyplot.scatter(dfAB1[row_ix, 0], dfAB1[row_ix, 1])
# show the plot
    pyplot.show()
