AttributeError: module 'tensorflow.compat.v1' has no attribute '
出现"AttributeError: module 'networkx' has no attribute 'bellman_ford'"的错误提示,说明在使用networkx库时,调用了该库中不存在的bellman_ford函数。解决该问题的方法如下:
1.检查networkx库的版本是否正确,可以使用以下命令升级networkx库:
```shell
pip install --upgrade networkx
```
2.检查代码中是否正确导入了networkx库,例如:
```python
import networkx as nx
```
3.检查代码中是否正确调用了bellman_ford函数,例如:
```python
G = nx.DiGraph()
# 添加节点和边
...
# 调用bellman_ford函数
path = nx.bellman_ford(G, source=0, weight='weight')
```
