问题描述
我有一个 networkx 图列表。我有一个包含以下信息的数据框:
Out[91]:
ln ln2
0 [[67,1],[67,... {0: [67,1: [67,2: [67,3: [67,1...
1 [[67,1...
2 [[67,1...
3 [[67,1...
4 [[67,1...
... ...
43244 [[71,[73,[79,[80,... {0: [71,1: [73,2: [79,3: [80,1...
43245 [[71,1...
43246 [[71,1...
43247 [[71,1...
43248 [[71,[82,1...
[43249 rows x 2 columns]
两列包含相同的信息,但一个是列表,一个是字典。我正在尝试遍历每个图及其各自的节点并添加相关的节点功能。
例如,graph[0] 在 df['ln' 或 'ln2'][0] 中有节点特征。我试过了:
for i in range(len(graphs)):
for j in range(len(df['ln'][i])):
for node_data in graphs[i].nodes(data=True):
node_data['feature'] = df['ln'][i][j]
并收到:
Traceback (most recent call last):
File "/home/anthony/anaconda3/envs/GeoDL/lib/python3.8/site-packages/IPython/core/interactiveshell.py",line 3427,in run_code

File "<ipython-input-75-894a20b5da94>",line 4,in <module>
node_data['feature'] = df['ln'][i][j]
TypeError: 'tuple' object does not support item assignment
我也尝试过对单个图形进行处理:
g0.nodes.data(df['ln'][0])

TypeError: unhashable type: 'list'
与 dict 相同的结果。
解决方法
我在分配数据之前更改了我的节点 ID,因此它无法识别新 ID。
