我的代码生成以下错误: TypeError: object() takes no parameters

class Graph(object):
    def vertices(self):
        return list(self.__graph_dict.keys())

if __name__ == "__main__":

    g = { "a" : ["d"],
          "b" : ["c"],
          "c" : ["b", "c", "d", "e"],
          "d" : ["a", "c"],
          "e" : ["c"],
          "f" : []
        }

    graph = Graph(g)

    print("Vertices of graph:")
    print(graph.vertices())

有没有办法解决这个问题？

我有这段代码：

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt



fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')



ax.scatter(data.FAC1_1, data.FAC2_1, data.FAC3_1, c='r', marker='o')

ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')
ax.set_zlabel('Z Label')

plt.show()

一切正常。唯一的问题是出来的散点图真的很小。有没有办法让它变大？我查看了文档，但找不到它。

谢谢你

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

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？
