python - KeyError：from_pandas_edge_list() 的“来源”

Question

这是我的代码：

import numpy as np
import pandas as pd
import networkx as nx

df = pd.read_excel(r"/path/to/file.xlsx", sheet_name="Sheet4")
df.edge=nx.from_pandas_edgelist(df,source='Abrev')
print(list(enumerate_all_cliques(nx.Graph(df.edge))))

if 给了我KeyError: 'Abrev'这个代码的一个关键错误，但我也尝试更改'Abrev'并0删除source='Abrev'所有代码，但每个错误都会略有不同；'KeyError: 0 'KeyError: 'source'

excel文件的示例内容；

Answer 1

只需添加，而您在前面nx.from_pandas_adjacency忘记了nx.enumerate_all_cliques

import numpy as np
import pandas as pd
import networkx as nx
import matplotlib.pyplot as plt

df = pd.read_excel(r"/path/to/file.xlsx", sheet_name="Sheet4",index_col=0,usecols = "A:E")
df.edge=nx.from_pandas_adjacency(df)
print(list(nx.enumerate_all_cliques(nx.Graph(df.edge))))
