tf.raw_ops.ResourceApplyCenteredRMSProp(
var, mg, ms, mom, lr, rho, momentum, epsilon, grad, use_locking=False, name=None

This often helps with training, but is slightly more expensive in terms of computation and memory. Note that in dense implementation of this algorithm, mg, ms, and mom will update even if the grad is zero, but in this sparse implementation, mg, ms, and mom will not update in iterations during which the grad is zero. mean_square = decay * mean_square + (1-decay) * gradient ** 2 mean_grad = decay * mean_grad + (1-decay) * gradient Delta = learning_rate * gradient / sqrt(mean_square + epsilon - mean_grad ** 2) mg <- rho * mg{t-1} + (1-rho) * grad ms <- rho * ms{t-1} + (1-rho) * grad * grad mom <- momentum * mom_{t-1} + lr * grad / sqrt(ms - mg * mg + epsilon) var <- var - mom

ref is a Tensor with rank P and indices is a Tensor of rank Q. indices must be integer tensor, containing indices into ref. It must be shape [d_0, ..., d_{Q-2}, K] where 0 < K <= P. The innermost dimension of indices (with length K) corresponds to indices into elements (if K = P) or slices (if K < P) along the Kth dimension of ref. updates is Tensor of rank Q-1+P-K with shape: [d_0, ..., d_{Q-2}, ref.shape[K], ..., ref.shape[P-1]]
For example, say we want to add 4 scattered elements to a rank-1 tensor to 8 elements. In Python, that addition would look like this: ref = tf.Variable([1, 2, 3, 4, 5, 6, 7, 8], use_resource=True)
indices = tf.constant([[4], [3], [1], [7]])
updates = tf.constant([9, 10, 11, 12])
add = tf.scatter_nd_add(ref, indices, updates)
with tf.Session() as sess:
print sess.run(add)
The resulting update to ref would look like this: [1, 13, 3, 14, 14, 6, 7, 20]

)
Note that in dense implementation of this algorithm, ms and mom will update even if the grad is zero, but in this sparse implementation, ms and mom will not update in iterations during which the grad is zero. mean_square = decay * mean_square + (1-decay) * gradient ** 2 Delta = learning_rate * gradient / sqrt(mean_square + epsilon) ms <- rho * ms{t-1} + (1-rho) * grad * grad mom <- momentum * mom{t-1} + lr * grad / sqrt(ms + epsilon) var <- var - mom

)
The values of value are assigned to the positions in the variable ref that are selected by the slice parameters. The slice parameters begin,end,strides, etc. work exactly as inStridedSlice`. NOTE this op currently does not support broadcasting and so value's shape must be exactly the shape produced by the slice of ref.

tf.raw_ops.Restore Restores a tensor from checkpoint files. View aliases Compat aliases for migration
See Migration guide for more details. tf.compat.v1.raw_ops.Restore
tf.raw_ops.Restore(
file_pattern, tensor_name, dt, preferred_shard=-1, name=None
)
Reads a tensor stored in one or several files. If there are several files (for instance because a tensor was saved as slices), file_pattern may contain wildcard symbols (* and ?) in the filename portion only, not in the directory portion. If a file_pattern matches several files, preferred_shard can be used to hint in which file the requested tensor is likely to be found. This op will first open the file at index preferred_shard in the list of matching files and try to restore tensors from that file. Only if some tensors or tensor slices are not found in that first file, then the Op opens all the files. Setting preferred_shard to match the value passed as the shard input of a matching Save Op may speed up Restore. This attribute only affects performance, not correctness. The default value -1 means files are processed in order. See also RestoreSlice.
Args
file_pattern A Tensor of type string. Must have a single element. The pattern of the files from which we read the tensor.
tensor_name A Tensor of type string. Must have a single element. The name of the tensor to be restored.
dt A tf.DType. The type of the tensor to be restored.
preferred_shard An optional int. Defaults to -1. Index of file to open first if multiple files match file_pattern.
name A name for the operation (optional).
Returns A Tensor of type dt. | tensorflow.raw_ops.restore |

See Migration guide for more details. tf.compat.v1.raw_ops.RestoreSlice
tf.raw_ops.RestoreSlice(
file_pattern, tensor_name, shape_and_slice, dt, preferred_shard=-1, name=None
)
This is like Restore except that restored tensor can be listed as filling only a slice of a larger tensor. shape_and_slice specifies the shape of the larger tensor and the slice that the restored tensor covers. The shape_and_slice input has the same format as the elements of the shapes_and_slices input of the SaveSlices op.
Args
file_pattern A Tensor of type string. Must have a single element. The pattern of the files from which we read the tensor.
tensor_name A Tensor of type string. Must have a single element. The name of the tensor to be restored.
shape_and_slice A Tensor of type string. Scalar. The shapes and slice specifications to use when restoring a tensors.
dt A tf.DType. The type of the tensor to be restored.
preferred_shard An optional int. Defaults to -1. Index of file to open first if multiple files match file_pattern. See the documentation for Restore.

tf.raw_ops.RestoreV2 Restores tensors from a V2 checkpoint. View aliases Compat aliases for migration
See Migration guide for more details. tf.compat.v1.raw_ops.RestoreV2
tf.raw_ops.RestoreV2(
prefix, tensor_names, shape_and_slices, dtypes, name=None
)
For backward compatibility with the V1 format, this Op currently allows restoring from a V1 checkpoint as well: This Op first attempts to find the V2 index file pointed to by "prefix", and if found proceed to read it as a V2 checkpoint; Otherwise the V1 read path is invoked. Relying on this behavior is not recommended, as the ability to fall back to read V1 might be deprecated and eventually removed. By default, restores the named tensors in full. If the caller wishes to restore specific slices of stored tensors, "shape_and_slices" should be non-empty strings and correspondingly well-formed. Callers must ensure all the named tensors are indeed stored in the checkpoint.
Args
prefix A Tensor of type string. Must have a single element. The prefix of a V2 checkpoint.
tensor_names A Tensor of type string. shape {N}. The names of the tensors to be restored.
shape_and_slices A Tensor of type string. shape {N}. The slice specs of the tensors to be restored. Empty strings indicate that they are non-partitioned tensors.
dtypes A list of tf.DTypes that has length >= 1. shape {N}. The list of expected dtype for the tensors. Must match those stored in the checkpoint.
name A name for the operation (optional).
Returns A list of Tensor objects of type dtypes. | tensorflow.raw_ops.restorev2 |

Given a tensor, and a bool tensor dims representing the dimensions of tensor, this operation reverses each dimension i of tensor where dims[i] is True. tensor can have up to 8 dimensions. The number of dimensions of tensor must equal the number of elements in dims. In other words: rank(tensor) = size(dims) For example: # tensor 't' is [[[[ 0, 1, 2, 3],
# [ 4, 5, 6, 7],
# [ 8, 9, 10, 11]],
# [[12, 13, 14, 15],
# [16, 17, 18, 19],
# [20, 21, 22, 23]]]]
# tensor 't' shape is [1, 2, 3, 4]

tf.raw_ops.ReverseSequence Reverses variable length slices. View aliases Compat aliases for migration
See Migration guide for more details. tf.compat.v1.raw_ops.ReverseSequence
tf.raw_ops.ReverseSequence(
input, seq_lengths, seq_dim, batch_dim=0, name=None
)
This op first slices input along the dimension batch_dim, and for each slice i, reverses the first seq_lengths[i] elements along the dimension seq_dim. The elements of seq_lengths must obey seq_lengths[i] <= input.dims[seq_dim], and seq_lengths must be a vector of length input.dims[batch_dim]. The output slice i along dimension batch_dim is then given by input slice i, with the first seq_lengths[i] slices along dimension seq_dim reversed. For example: # Given this:
batch_dim = 0
seq_dim = 1
input.dims = (4, 8, ...)
seq_lengths = [7, 2, 3, 5]
# then slices of input are reversed on seq_dim, but only up to seq_lengths:
output[0, 0:7, :, ...] = input[0, 7:0:-1, :, ...]
output[1, 0:2, :, ...] = input[1, 2:0:-1, :, ...]
output[2, 0:3, :, ...] = input[2, 3:0:-1, :, ...]
output[3, 0:5, :, ...] = input[3, 5:0:-1, :, ...]

output[1, 2:, :, ...] = input[1, 2:, :, ...]
output[2, 3:, :, ...] = input[2, 3:, :, ...]
output[3, 2:, :, ...] = input[3, 2:, :, ...]
In contrast, if: # Given this:
batch_dim = 2
seq_dim = 0
input.dims = (8, ?, 4, ...)
seq_lengths = [7, 2, 3, 5]

Bounding box annotations are often supplied in addition to ground-truth labels in image recognition or object localization tasks. A common technique for training such a system is to randomly distort an image while preserving its content, i.e. data augmentation. This Op outputs a randomly distorted localization of an object, i.e. bounding box, given an image_size, bounding_boxes and a series of constraints. The output of this Op is a single bounding box that may be used to crop the original image. The output is returned as 3 tensors: begin, size and bboxes. The first 2 tensors can be fed directly into tf.slice to crop the image. The latter may be supplied to tf.image.draw_bounding_boxes to visualize what the bounding box looks like. Bounding boxes are supplied and returned as [y_min, x_min, y_max, x_max]. The bounding box coordinates are floats in [0.0, 1.0] relative to the width and height of the underlying image. For example, # Generate a single distorted bounding box.

tf.raw_ops.ScatterNd Scatter updates into a new tensor according to indices. View aliases Compat aliases for migration
See Migration guide for more details. tf.compat.v1.raw_ops.ScatterNd
tf.raw_ops.ScatterNd(
indices, updates, shape, name=None
)
Creates a new tensor by applying sparse updates to individual values or slices within a tensor (initially zero for numeric, empty for string) of the given shape according to indices. This operator is the inverse of the tf.gather_nd operator which extracts values or slices from a given tensor. This operation is similar to tensor_scatter_add, except that the tensor is zero-initialized. Calling tf.scatter_nd(indices, values, shape) is identical to tensor_scatter_add(tf.zeros(shape, values.dtype), indices, values) If indices contains duplicates, then their updates are accumulated (summed). Warning: The order in which updates are applied is nondeterministic, so the output will be nondeterministic if indices contains duplicates -- because of some numerical approximation issues, numbers summed in different order may yield different results. indices is an integer tensor containing indices into a new tensor of shape shape. The last dimension of indices can be at most the rank of shape: indices.shape[-1] <= shape.rank
The last dimension of indices corresponds to indices into elements (if indices.shape[-1] = shape.rank) or slices (if indices.shape[-1] < shape.rank) along dimension indices.shape[-1] of shape. updates is a tensor with shape indices.shape[:-1] + shape[indices.shape[-1]:]
The simplest form of scatter is to insert individual elements in a tensor by index. For example, say we want to insert 4 scattered elements in a rank-1 tensor with 8 elements. In Python, this scatter operation would look like this: indices = tf.constant([[4], [3], [1], [7]])
updates = tf.constant([9, 10, 11, 12])
shape = tf.constant([8])
scatter = tf.scatter_nd(indices, updates, shape)
print(scatter)
The resulting tensor would look like this: [0, 11, 0, 10, 9, 0, 0, 12]
We can also, insert entire slices of a higher rank tensor all at once. For example, if we wanted to insert two slices in the first dimension of a rank-3 tensor with two matrices of new values. In Python, this scatter operation would look like this: indices = tf.constant([[0], [2]])
updates = tf.constant([[[5, 5, 5, 5], [6, 6, 6, 6],
[7, 7, 7, 7], [8, 8, 8, 8]],
[[5, 5, 5, 5], [6, 6, 6, 6],
[7, 7, 7, 7], [8, 8, 8, 8]]])
shape = tf.constant([4, 4, 4])
scatter = tf.scatter_nd(indices, updates, shape)
print(scatter)
The resulting tensor would look like this: [[[5, 5, 5, 5], [6, 6, 6, 6], [7, 7, 7, 7], [8, 8, 8, 8]],
[[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]],
[[5, 5, 5, 5], [6, 6, 6, 6], [7, 7, 7, 7], [8, 8, 8, 8]],
[[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]]]
Note that on CPU, if an out of bound index is found, an error is returned. On GPU, if an out of bound index is found, the index is ignored.

tf.raw_ops.ScatterNdSub(
ref, indices, updates, use_locking=False, name=None
)
within a given variable according to indices. ref is a Tensor with rank P and indices is a Tensor of rank Q. indices must be integer tensor, containing indices into ref. It must be shape [d_0, ..., d_{Q-2}, K] where 0 < K <= P. The innermost dimension of indices (with length K) corresponds to indices into elements (if K = P) or slices (if K < P) along the Kth dimension of ref. updates is Tensor of rank Q-1+P-K with shape: [d_0, ..., d_{Q-2}, ref.shape[K], ..., ref.shape[P-1]]
For example, say we want to subtract 4 scattered elements from a rank-1 tensor with 8 elements. In Python, that subtraction would look like this: ref = tf.Variable([1, 2, 3, 4, 5, 6, 7, 8])
indices = tf.constant([[4], [3], [1], [7]])
updates = tf.constant([9, 10, 11, 12])
sub = tf.scatter_nd_sub(ref, indices, updates)
with tf.Session() as sess:
print sess.run(sub)
The resulting update to ref would look like this: [1, -9, 3, -6, -4, 6, 7, -4]
See tf.scatter_nd for more details about how to make updates to slices.
Args
ref A mutable Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, uint16, complex128, half, uint32, uint64. A mutable Tensor. Should be from a Variable node.
indices A Tensor. Must be one of the following types: int32, int64. A Tensor. Must be one of the following types: int32, int64. A tensor of indices into ref.
updates A Tensor. Must have the same type as ref. A Tensor. Must have the same type as ref. A tensor of updated values to subtract from ref.
use_locking An optional bool. Defaults to False. An optional bool. Defaults to True. If True, the assignment will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
name A name for the operation (optional).
Returns A mutable Tensor. Has the same type as ref. | tensorflow.raw_ops.scatterndsub |
