Function bincount

Counts the number of occurrences of each value in an integer array. If `minlength` and `maxlength` are not given, returns a vector with length `tf.reduce_max(arr) + 1` if `arr` is non-empty, and length 0 otherwise. If `weights` are non-None, then index `i` of the output stores the sum of the

(arr,
             weights=None,
             minlength=None,
             maxlength=None,
             dtype=dtypes.int32)
