如何从python中的igraph导出？

Question

我编写了此代码以将数据转换为 .gml 格式，但出现此错误。 我该怎么办？

TypeError: descriptor 'write_gml' for 'igraph._igraph.GraphBase' objects doesn't apply to a 'str' object

代码：

import igraph as ig
import pandas as pd


a = pd.DataFrame(Matrix, index=tags, columns=tags)


# # Get the values as np.array, it's more convenenient.
A = a.values
# print(A)
# # Create graph, A.astype(bool).tolist() or (A / A).tolist() can also be used.
g = igraph.Graph.Adjacency((A > 0).tolist())

# # Add edge weights and node labels.
g.es['weight'] = A[A.nonzero()]
g.vs['label'] = tags  # or a.index/a.columns

ig.Graph.write_gml('test.gml')

Answer 1

你需要调用g.write_gml(filename) ，如果你想写的图形g到filename 。
