   May 2, 2013 · This is a tricky problem, since there is not much out there to calculate mode along an axis. The solution is straight forward for 1-D arrays, where numpy.bincount is handy, along with numpy.unique with the return_counts arg as True. The most common n-dimensional function I see is scipy.stats.mode, although it is prohibitively slow- especially ...
