While using histogram2d on simple examples I got these errors: import numpy x = numpy.array([0,0]) y = numpy.array([0,1]) numpy.histogram2d(x,y,bins=[2,2]) ----------------------------------------------------------------- Warning: divide by zero encountered in log10 --------------------------------------------------------------------------- exceptions.OverflowError Traceback (most recent call last)
