AttributeError: module 'networkx' has no attribute 'connected_component_subgraphs' about chinese-postman HOT 8 CLOSED

Found a solution which works:

> def connected_component_subgraphs(G):
    for c in nx.connected_components(G):
        yield G.subgraph(c)

from chinese-postman.

Seems like it's still present up till 2.3, and removed in 2.4.

Deprecation notice says this is the replacement:

G.subgraph(c) for c in connected_components(G)

Until this is fixed, just stick to networkx 2.3 or earlier.

This has already been fixed in the master branch.

This is also an issue in mordred for some reason. Any ideas?

module 'networkx' has no attribute 'biconnected_component_subgraphs' (SpAbs_Dt/SpAbs/mordred._matrix_attributes.Eigen(mordred.DetourMatrix.DetourMatrixCache())/mordred.DetourMatrix.DetourMatrixCache())

It seems that they are working on that, mordred-descriptor/mordred#84. So you can just basically stick to networkx with version 2.3 in your virtual environment,

pip install --force-reinstall networkx==2.3

This will fix your problem of using mordred.

Thank you it works

from chinese-postman.

def connected_component_subgraphs(G):
for c in nx.connected_components(G):
yield G.subgraph(c)

This did not work for me; I get the same error as before. Am I supposed to just run it in the Python console first?

Ok even more mind boggling, after shaving the yak for a while here trying to get this to work is that I found that the only networkx on the system is this one:

networkx-1.7-py2.7.egg

This is surely version 1.7 which is < 2.4 and thus should not be a problem, right? I'm about to figure out how to tear the egg apart, manually editing the file as needed, and reassemble it. This is ridiculous.
