可能maxflow包维护的不行，安装另外一个包
pip3 install PyMaxflow
实在不行，定位到
maxflow的__init__.py

maxflow
=======
``maxflow`` is a Python module for max-flow/min-cut computations. It wraps
the C++ maxflow library by Vladimir Kolmogorov, which implements the
algorithm described in
An Experimental Comparison of Min-Cut/Max-Flow Algorithms for Energy
Minimization in Vision. Yuri Boykov and Vladimir Kolmogorov. TPAMI.
This module aims to simplify the construction of graphs with complex
layouts. It provides two Graph classes, ``Graph[int]`` and ``Graph[float]``,
for integer and real data types.
Example:
>>> import maxflow
>>> g = maxflow.Graph[int](2, 2)
>>> nodes = g.add_nodes(2)
>>> g.add_edge(nodes[0], nodes[1], 1, 2)
>>> g.add_tedge(nodes[0], 2, 5)
>>> g.add_tedge(nodes[1], 9, 4)
>>> g.maxflow()
8
>>> g.get_grid_segments(nodes)
array([ True, False])
If you use this library for research purposes, you must cite the aforementioned
paper in any resulting publication.
