I went to /pip help install/ and tried several install requirements but
none of them worked for me.
I had not realised that metis was ‘alpha software’ when I visited
https://metis.readthedocs.org/en/latest/#. I understood it to be
available and the example code looked just what I was looking for.
Well the below in the documentation is wrong :
"
It’s on PyPI, so installation should be as easy as:
pip install metis
-or-
easy_install metis
"
There is no actual file on PyPi. To get it to install, I went to(from
the Download URL on the PyPi page) to here:
https://bitbucket.org/kw/metis-python/downloads
and downloaded the repo, unzipped it and then ran:
python setup.py install
If it where me I would go here:
https://bitbucket.org/kw/metis-python
and file a bug report
FYI the last commit to the code was 2013-10-10. so I would not hold out
great hopes.
Are you able to execute that example as below? If so perhaps it
might help to isolate my problem.
No, because I do not have Metis or Networkx installed.
import networkx as nx
import metis
G = metis.example_networkx()
(edgecuts, parts) = metis.part_graph(G, 3)
colors = ['red','blue','green']
for i, p in enumerate(parts):
... G.node[i]['color'] = colors[p]
...
nx.write_dot(G, 'example.dot') # Requires pydot or pygraphviz
