sequences of bin edges. If int[], defines the number of equal-
        width bins in each dimension. If int, defines the number of
        equal-width bins for all dimensions.
Keyword Arguments:
      * range (sequence of python:float) -- Defines the leftmost
        and rightmost bin edges in each dimension.
  * **weight** (*Tensor*) -- By default, each value in the input
    has weight 1. If a weight tensor is passed, each N-dimensional
    coordinate in input contributes its associated weight towards
    its bin's result. The weight tensor should have the same shape
    as the "input" tensor excluding its innermost dimension N.

  * **density** (*bool*) -- If False (default), the result will
    contain the count (or total weight) in each bin. If True, each
    count (weight) is divided by the total count (total weight),
    then divided by the volume of its associated bin.

Returns:
      N-dimensional Tensor containing the values of the histogram.
