Python alternative for calculating pairwise distance between two sets of 2d points [duplicate]

Answer 1

You should check the pairwise_distances method of the scikit-learn package.

sklearn.metrics.pairwise.pairwise_distances(X, Y=None, metric='euclidean', n_jobs=1, **kwds)

More information in http://scikit-learn.org/stable/modules/generated/sklearn.metrics.pairwise.pairwise_distances.html
