dbscan索引超出了python范围

Question

这是我的代码.

from sklearn.cluster import DBSCAN

dbscan = DBSCAN(random_state=111)

dbscan.fit(data3)

data3是一个pandas数据帧:

      FAC1_2    FAC2_2
0   -0.227252 -0.685482
1    0.015251 -0.988252
2   -0.291176 -0.696146
3   -0.747702 -0.708030
4   -0.648103 -0.701741
5   -0.546777 -0.906151
6   -0.141553 -0.689223
7    0.159203 -0.734537
8    0.345847 -0.900163
9   -0.049349 -0.700356
10   0.079924 -0.651371

我收到以下错误:

File "/anaconda/anaconda/lib/python3.4/site-packages/pandas/core/indexing.py", line 1632, in _maybe_convert_indices
raise IndexError("indices are out-of-bounds")

IndexError: indices are out-of-bounds

问题是什么？

Answer 1

问题是一个错误.它不适用于pandas数据帧.解决方案是将pandas数据帧转换为numpy数组:

data3 = np.array(data3)
