Partitioner base class: all partitiners inherit from this class.
Partitioners should implement a __call__
method with the following
signature:
def __call__(self, shape, dtype, axis=0):
# Partitions the given `shape` and returns the partition results.
# See docstring of `__call__` method for the format of partition results.
Methods
__call__
View source
__call__(
shape, dtype, axis=0
)
Partitions the given shape
and returns the partition results.
Examples of a partitioner that allocates a fixed number of shards:
partitioner = FixedShardsPartitioner(num_shards=2)
partitions = partitioner(tf.TensorShape([10, 3], tf.float32), axis=0)
print(partitions) # [2, 0]
Args |
shape
|
a tf.TensorShape , the shape to partition.
|
dtype
|
a tf.dtypes.Dtype indicating the type of the partition value.
|
axis
|
The axis to partition along. Default: outermost axis.
|
Returns |
A list of integers representing the number of partitions on each axis,
where i-th value correponds to i-th axis.
