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