How can I calculate distances with points in a huge matrix, 70000 rows, 6 columns?

Question

the matrix is about 70000 rows, 6 columns, the first two columns are x, y coordinates, the last four columns do not participate in calculation...

the code is

distances = sklearn.metrics.pairwise.pairwise_distances(polygon_centers[:, 0:2], metric='euclidean', n_jobs=1)

the Pycharm report Memory Error...... How can I do this Euclidean distance calculation?
