数据框中的节点特征到 networkx 图形列表

如何解决数据框中的节点特征到 networkx 图形列表

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
    exec(code_obj,self.user_global_ns,self.user_ns)
  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])
Out[88]: Traceback (most recent call last):
  File "/home/anthony/anaconda3/envs/GeoDL/lib/python3.8/site-packages/IPython/core/formatters.py",line 224,in catch_format_error
    r = method(self,*args,**kwargs)
  File "/home/anthony/anaconda3/envs/GeoDL/lib/python3.8/site-packages/IPython/core/formatters.py",line 702,in __call__
    printer.pretty(obj)
  File "/home/anthony/anaconda3/envs/GeoDL/lib/python3.8/site-packages/IPython/lib/pretty.py",line 394,in pretty
    return _repr_pprint(obj,self,cycle)
  File "/home/anthony/anaconda3/envs/GeoDL/lib/python3.8/site-packages/IPython/lib/pretty.py",line 700,in _repr_pprint
    output = repr(obj)
  File "/home/anthony/anaconda3/envs/GeoDL/lib/python3.8/site-packages/networkx/classes/reportviews.py",line 302,in __repr__
    return f"{name}({dict(self)},data={self._data!r})"
  File "/home/anthony/anaconda3/envs/GeoDL/lib/python3.8/site-packages/networkx/classes/reportviews.py",line 268,in <genexpr>
    (n,dd[data] if data in dd else self._default)
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。
