Cannot import Node2Vec

[chuymtz]

Hello,

From running

from node2vec import Node2Vec

I get an import error. It seems that it tries to run the script nx_pylab.py.

UserWarning: No data for colormapping provided via 'c'. Parameters 'cmap' will be ignored
  node_collection = ax.scatter(
Node2Vec accuracy = 95.45%
Node2Vec accuracy = 72.73%

When i go to this cript i see its under the networkx pkg/drawing/ directory and the problem line is

node_collection = ax.scatter(
        xy[:, 0],
        xy[:, 1],
        s=node_size,
        c=node_color,
        marker=node_shape,
        cmap=cmap,
        vmin=vmin,
        vmax=vmax,
        alpha=alpha,
        linewidths=linewidths,
        edgecolors=edgecolors,
        label=label,
    )

I've attempted this on both python 3.8 and 3.10. This is windows.

Hi, can you show me the output of pip freeze for the environment you are using?

Seems to me it's more about the matplotlib than anything. Perhaps an issue with my networkx version?

You should use
from node2vec.node2vec import Node2Vec
because Node2Vec in the file node2vec.py

That is actually not true, because in node2vec/__init__.py I excplicitly import Node2Vec so it should be available...

I hadn't had time to debug this as I don't have enough time for this project... sorry

Hi chuymtz, make sure your script isn't named node2vec.py. This could lead to circular imports.
