tf.raw_ops.BatchFunction Batches all the inputs tensors to the computation done by the function. View aliases Compat aliases for migration
See Migration guide for more details. tf.compat.v1.raw_ops.BatchFunction
tf.raw_ops.BatchFunction(
in_tensors, captured_tensors, f, num_batch_threads, max_batch_size,
batch_timeout_micros, Tout, max_enqueued_batches=10, allowed_batch_sizes=[],
container='', shared_name='', batching_queue='',
enable_large_batch_splitting=False, name=None
)
So, for example, in the following code
# This input will be captured.
y = tf.placeholder_with_default(1.0, shape=[])
@tf.Defun(tf.float32)
def computation(a):
return tf.matmul(a, a) + y
b = gen_batch_ops.batch_function(
f=computation
in_tensors=[a],
captured_tensors=computation.captured_inputs,
Tout=[o.type for o in computation.definition.signature.output_arg],
num_batch_threads=1,
max_batch_size=10,
batch_timeout_micros=100000, # 100ms
allowed_batch_sizes=[3, 10],
batching_queue="")
If more than one session.run call is simultaneously trying to compute b the values of a will be gathered, non-deterministically concatenated along the first axis, and only one thread will run the computation. Assumes that all arguments of the function are Tensors which will be batched along their first dimension. Arguments that are captured, are not batched. The session.run call which does the concatenation, will use the values of the captured tensors available to it. Therefore, typical uses of captured tensors should involve values which remain unchanged across session.run calls. Inference is a good example of this. SparseTensor is not supported. The return value of the decorated function must be a Tensor or a list/tuple of Tensors.
Args
in_tensors A list of Tensor objects. The tensors to be batched.
captured_tensors A list of Tensor objects. The tensors which are captured in the function, and don't need to be batched.

allowed_batch_sizes An optional list of ints. Defaults to []. Optional list of allowed batch sizes. If left empty, does nothing. Otherwise, supplies a list of batch sizes, causing the op to pad batches up to one of those sizes. The entries must increase monotonically. If enable_large_batch_splitting is false (i.e., large-input-split is not enabled) the final entry must equal max_batch_size.
container An optional string. Defaults to "". Controls the scope of sharing of this batch.
shared_name An optional string. Defaults to "". Concurrently running instances of batch in the same device with the same container and shared_name will batch their elements together. If left empty, the op name will be used as the shared name.
batching_queue An optional string. Defaults to "".

See Migration guide for more details. tf.compat.v1.raw_ops.BatchToSpace
tf.raw_ops.BatchToSpace(
input, crops, block_size, name=None
)
This is a legacy version of the more general BatchToSpaceND. Rearranges (permutes) data from batch into blocks of spatial data, followed by cropping. This is the reverse transformation of SpaceToBatch. More specifically, this op outputs a copy of the input tensor where values from the batch dimension are moved in spatial blocks to the height and width dimensions, followed by cropping along the height and width dimensions.
Args
input A Tensor. 4-D tensor with shape [batch*block_size*block_size, height_pad/block_size, width_pad/block_size, depth]. Note that the batch size of the input tensor must be divisible by block_size * block_size.
crops A Tensor. Must be one of the following types: int32, int64. 2-D tensor of non-negative integers with shape [2, 2]. It specifies how many elements to crop from the intermediate result across the spatial dimensions as follows: crops = [[crop_top, crop_bottom], [crop_left, crop_right]]
block_size An int that is >= 2.
name A name for the operation (optional).
Returns A Tensor. Has the same type as input. | tensorflow.raw_ops.batchtospace |

See Migration guide for more details. tf.compat.v1.raw_ops.BatchToSpaceND
tf.raw_ops.BatchToSpaceND(
input, block_shape, crops, name=None
)
This operation reshapes the "batch" dimension 0 into M + 1 dimensions of shape block_shape + [batch], interleaves these blocks back into the grid defined by the spatial dimensions [1, ..., M], to obtain a result with the same rank as the input. The spatial dimensions of this intermediate result are then optionally cropped according to crops to produce the output. This is the reverse of SpaceToBatch. See below for a precise description.
Args
input A Tensor. N-D with shape input_shape = [batch] + spatial_shape + remaining_shape, where spatial_shape has M dimensions.
block_shape A Tensor. Must be one of the following types: int32, int64. 1-D with shape [M], all values must be >= 1.
crops A Tensor. Must be one of the following types: int32, int64. 2-D with shape [M, 2], all values must be >= 0. crops[i] = [crop_start, crop_end] specifies the amount to crop from input dimension i + 1, which corresponds to spatial dimension i. It is required that crop_start[i] + crop_end[i] <= block_shape[i] * input_shape[i + 1]. This operation is equivalent to the following steps: Reshape input to reshaped of shape: [block_shape[0], ..., block_shape[M-1], batch / prod(block_shape), input_shape[1], ..., input_shape[N-1]] Permute dimensions of reshaped to produce permuted of shape [batch / prod(block_shape), input_shape[1], block_shape[0], ..., input_shape[M], block_shape[M-1], input_shape[M+1], ..., input_shape[N-1]] Reshape permuted to produce reshaped_permuted of shape [batch / prod(block_shape), input_shape[1] * block_shape[0], ..., input_shape[M] * block_shape[M-1], input_shape[M+1], ..., input_shape[N-1]] Crop the start and end of dimensions [1, ..., M] of reshaped_permuted according to crops to produce the output of shape: [batch / prod(block_shape), input_shape[1] * block_shape[0] - crops[0,0] - crops[0,1], ..., input_shape[M] * block_shape[M-1] - crops[M-1,0] - crops[M-1,1], input_shape[M+1], ..., input_shape[N-1]] Some examples: (1) For the following input of shape [4, 1, 1, 1], block_shape = [2, 2], and crops = [[0, 0], [0, 0]]: [[[[1]]], [[[2]]], [[[3]]], [[[4]]]]

tf.raw_ops.Bitcast Bitcasts a tensor from one type to another without copying data. View aliases Compat aliases for migration
See Migration guide for more details. tf.compat.v1.raw_ops.Bitcast
tf.raw_ops.Bitcast(
input, type, name=None
)
Given a tensor input, this operation returns a tensor that has the same buffer data as input with datatype type. If the input datatype T is larger than the output datatype type then the shape changes from [...] to [..., sizeof(T)/sizeof(type)]. If T is smaller than type, the operator requires that the rightmost dimension be equal to sizeof(type)/sizeof(T). The shape then goes from [..., sizeof(type)/sizeof(T)] to [...]. tf.bitcast() and tf.cast() work differently when real dtype is casted as a complex dtype (e.g. tf.complex64 or tf.complex128) as tf.cast() make imaginary part 0 while tf.bitcast() gives module error. For example, Example 1:
a = [1., 2., 3.]
equality_bitcast = tf.bitcast(a, tf.complex128)
Traceback (most recent call last):
InvalidArgumentError: Cannot bitcast from 1 to 18 [Op:Bitcast]
equality_cast = tf.cast(a, tf.complex128)
print(equality_cast)
tf.Tensor([1.+0.j 2.+0.j 3.+0.j], shape=(3,), dtype=complex128)
Example 2:
tf.bitcast(tf.constant(0xffffffff, dtype=tf.uint32), tf.uint8)
<tf.Tensor: shape=(4,), dtype=uint8, numpy=array([255, 255, 255, 255], dtype=uint8)>
Example 3:
x = [1., 2., 3.]
y = [0., 2., 3.]
equality= tf.equal(x,y)
equality_cast = tf.cast(equality,tf.float32)
equality_bitcast = tf.bitcast(equality_cast,tf.uint8)
print(equality)
tf.Tensor([False True True], shape=(3,), dtype=bool)
print(equality_cast)
tf.Tensor([0. 1. 1.], shape=(3,), dtype=float32)
print(equality_bitcast)
tf.Tensor(
[[ 0 0 0 0]
[ 0 0 128 63]
[ 0 0 128 63]], shape=(3, 4), dtype=uint8)
Note: Bitcast is implemented as a low-level cast, so machines with different endian orderings will give different results.
Args

tf.raw_ops.BroadcastTo Broadcast an array for a compatible shape. View aliases Compat aliases for migration
See Migration guide for more details. tf.compat.v1.raw_ops.BroadcastTo
tf.raw_ops.BroadcastTo(
input, shape, name=None
)
Broadcasting is the process of making arrays to have compatible shapes for arithmetic operations. Two shapes are compatible if for each dimension pair they are either equal or one of them is one. When trying to broadcast a Tensor to a shape, it starts with the trailing dimensions, and works its way forward. For example,
x = tf.constant([1, 2, 3])
y = tf.broadcast_to(x, [3, 3])
print(y)
tf.Tensor(
[[1 2 3]
[1 2 3]
[1 2 3]], shape=(3, 3), dtype=int32)
In the above example, the input Tensor with the shape of [1, 3] is broadcasted to output Tensor with shape of [3, 3]. When doing broadcasted operations such as multiplying a tensor by a scalar, broadcasting (usually) confers some time or space benefit, as the broadcasted tensor is never materialized. However, broadcast_to does not carry with it any such benefits. The newly-created tensor takes the full memory of the broadcasted shape. (In a graph context, broadcast_to might be fused to subsequent operation and then be optimized away, however.)
Args
input A Tensor. A Tensor to broadcast.
shape A Tensor. Must be one of the following types: int32, int64. An 1-D int Tensor. The shape of the desired output.
name A name for the operation (optional).
Returns A Tensor. Has the same type as input. | tensorflow.raw_ops.broadcastto |
