Partitioner to allocate minimum size per slice.

Returns a partitioner that partitions the variable of given shape and dtype such that each partition has a minimum of min_slice_size slice of the variable. The maximum number of such partitions (upper bound) is given by max_partitions.

max_partitions Upper bound on the number of partitions. Defaults to 1.
axis Axis along which to partition the variable. Defaults to 0.
min_slice_size Minimum size of the variable slice per partition. Defaults to 256K.
bytes_per_string_element If the Variable is of type string, this provides an estimate of how large each scalar in the Variable is.

A partition function usable as the partitioner argument to variable_scope and get_variable.
