tfl.broadcast_to (::mlir::TFL::BroadcastToOp)

Uyumlu bir şekil için bir dizi yayınlayın.

Yayın, aritmetik işlemler için uyumlu şekillere sahip diziler yapma sürecidir. Her bir boyut çifti için eşitse veya bunlardan biri bir ise iki şekil uyumludur. Bir şekle bir Tensör yayınlamaya çalışırken, takip eden boyutlarla başlar ve ileriye doğru ilerler.

Örneğin,

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]], şekil=(3, 3), dtype=int32)

Yukarıdaki örnekte, [1, 3] şeklindeki giriş Tensörü, [3, 3] şeklindeki çıkış Tensörü'ne yayınlanır.

Bir tensörü bir skaler ile çarpma gibi yayınlanmış işlemler yaparken, yayın (genellikle) yayınlanmış tensör hiçbir zaman gerçekleşmediği için biraz zaman veya mekan faydası sağlar.

Ancak, broadcast_to bu tür faydaları beraberinde getirmez. Yeni oluşturulan tensör, yayınlanan şeklin tüm belleğini alır. (Bir grafik bağlamında, broadcast_to sonraki işlemle kaynaştırılabilir ve daha sonra optimize edilebilir.)

tfl.expand_dims (::mlir::TFL::ExpandDimsOp)

Bir tensörün şekline 1 boyutu ekler.

Bir tensör input verildiğinde, bu işlem input şeklinin boyut indeks axis 1 boyutu ekler. Boyut indeks axis sıfırdan başlar; axis için negatif bir sayı belirtirseniz, sondan geriye doğru sayılır.

Bu işlem, tek bir öğeye toplu iş boyutu eklemek istiyorsanız kullanışlıdır. Örneğin, [height, width, channels] şeklinde tek bir görüntünüz varsa, bunu expand_dims(image, 0) ile 1 görüntüden oluşan bir toplu iş yapabilirsiniz, bu da şekli [1, height, width, channels] yapacaktır. .

Diğer örnekler:

# 't' is a tensor of shape [2]
shape(expand_dims(t, 0)) ==> [1, 2]
shape(expand_dims(t, 1)) ==> [2, 1]
shape(expand_dims(t, -1)) ==> [2, 1]

# 't2' is a tensor of shape [2, 3, 5]
shape(expand_dims(t2, 0)) ==> [1, 2, 3, 5]
shape(expand_dims(t2, 2)) ==> [2, 3, 1, 5]
shape(expand_dims(t2, 3)) ==> [2, 3, 5, 1]

Bu işlem şunları gerektirir:

-1-input.dims() <= dim <= input.dims()

This operation is related to squeeze() , which removes dimensions of size 1.

tfl.if (::mlir::TFL::IfOp)

if-then-else operation

The tfl.if operation represents an if-then-else construct for conditionally executing two regions of code. The operand to an if operation is a boolean value. For example:

tfl.if %b  {
  ...
} else {
  ...
}

tfl.if may also return results that are defined in its regions. The values defined are determined by which execution path is taken.

Example:

%x, %y = tfl.if %b -> (tensor<f32>, tensor<f32>) {
  %x_true = ...
  %y_true = ...
  tfl.yield %x_true, %y_true : tensor<f32>, tensor<f32>
} else {
  %x_false = ...
  %y_false = ...
  tfl.yield %x_false, %y_false : tensor<f32>, tensor<f32>
}

tfl.if regions are always terminated with "tfl.yield". If "tfl.if" defines no values, the "tfl.yield" can be left out, and will be inserted implicitly. Otherwise, it must be explicit. Also, if "tfl.if" defines one or more values, the 'else' block cannot be omitted.

Example:

tfl.if %b  {

tfl.non_max_suppression_v4 (::mlir::TFL::NonMaxSuppressionV4Op)

Greedily selects a subset of bounding boxes in descending order of score,

pruning away boxes that have high intersection-over-union (IOU) overlap with previously selected boxes. Bounding boxes with score less than score_threshold are removed. Bounding boxes are supplied as [y1, x1, y2, x2], where (y1, x1) and (y2, x2) are the coordinates of any diagonal pair of box corners and the coordinates can be provided as normalized (ie, lying in the interval [0, 1]) or absolute. Note that this algorithm is agnostic to where the origin is in the coordinate system and more generally is invariant to orthogonal transformations and translations of the coordinate system; thus translating or reflections of the coordinate system result in the same boxes being selected by the algorithm. The output of this operation is a set of integers indexing into the input collection of bounding boxes representing the selected boxes. The bounding box coordinates corresponding to the selected indices can then be obtained using the tf.gather operation . For example: selected_indices = tf.image.non_max_suppression_v2( boxes, scores, max_output_size, iou_threshold, score_threshold) selected_boxes = tf.gather(boxes, selected_indices)

For example: selected_indices = tf.image.non_max_suppression_v2( boxes, scores, max_output_size, iou_threshold, score_threshold) selected_boxes = tf.gather(boxes, selected_indices) This op also supports a Soft-NMS (with Gaussian weighting) mode (cf Bodla et al, https://arxiv.org/abs/1704.04503 ) where boxes reduce the score of other overlapping boxes instead of directly causing them to be pruned. To enable this Soft-NMS mode, set the soft_nms_sigma parameter to be larger than 0.

tfl.pack (::mlir::TFL::PackOp)

Packs a list of tensors along a dimension into one tensor

Packs a list of values_count rank- R tensors into one rank- (R+1) tensor.

Packs the values_count tensors in values into a tensor with rank one higher than each tensor in values , by packing them along the axis dimension.

Given a list of tensors of shape (A, B, C) ;

if axis == 0 then the output tensor will have the shape (N, A, B, C) . if axis == 1 then the output tensor will have the shape (A, N, B, C) . Etc.

For example:

# 'x' is [1, 4]
# 'y' is [2, 5]
# 'z' is [3, 6]
pack([x, y, z]) => [[1, 4], [2, 5], [3, 6]]  # Pack along first dim.
pack([x, y, z], axis=1) => [[1, 2, 3], [4, 5, 6]]

This is the opposite of unpack .

tfl.pad (::mlir::TFL::PadOp)

Padding operator

This operation pads a input with zeros according to the paddings you specify. paddings is an integer tensor with shape [Dn, 2] , where n is the rank of input . For each dimension D of input , paddings[D, 0] indicates how many zeros to add before the contents of input in that dimension, and paddings[D, 1] indicates how many zeros to add after the contents of input in that dimension.

The padded size of each dimension D of the output is:

paddings(D, 0) + input.dim_size(D) + paddings(D, 1)

For example:

# 't' is [[1, 1], [2, 2]]
# 'paddings' is [[1, 1], [2, 2]]
# rank of 't' is 2
pad(t, paddings) ==> [[0, 0, 0, 0, 0, 0]

Along each axis RFFT2D is computed on, if fft_length is smaller than the corresponding dimension of input , the dimension is cropped. If it is larger, the dimension is padded with zeros.

If axis == 0 then the i'th tensor in output is the slice value[i, :, :, :] and each tensor in output will have shape (B, C, D) . (Note that the dimension unpacked along is gone, unlike split ).

If axis == 1 then the i'th tensor in output is the slice value[:, i, :, :] and each tensor in output will have shape (A, C, D) . Etc.

tfl.while (::mlir::TFL::WhileOp)

While loop

output = input; while (cond(output)) { output = body(output) }

While loop where all values are passes through arguments with implicit capture.

input: A list of input tensors whose types are T. output: A list of output tensors whose types are T. cond: A region that takes 'input' and returns a boolean scalar tensor. body: A region that takes a list of tensors and returns another list of tensors. Both lists have the same types.

Traits: SingleBlockImplicitTerminator

Interfaces: LoopLikeOpInterface, TflRuntimeVerifyOpInterface

Attributes:

Attribute MLIR Type Description
is_stateless ::mlir::BoolAttr bool attribute

Operands:

Operand Description
input tensor of any type values

Results:

Result Description
output tensor of any type values

tfl.yield (::mlir::TFL::YieldOp)

Yield operation

The "yield" operation represents a return operation within the conditional and body of structured control flow (eg, while). The operation takes variable number of operands and produces no results. The operand number and types must match the signature of the region that contains the operation.

Traits: QuantizableResult, Terminator

Interfaces: NoSideEffect (MemoryEffectOpInterface), TflRuntimeVerifyOpInterface

Effects: MemoryEffects::Effect{}

Operands:

Operand Description
operands any type

tfl.zeros_like (::mlir::TFL::ZerosLikeOp)

ZerosLike operator

Returns a tensor of zeros with the same shape and type as the input tensor.

Traits: SameOperandsAndResultShape

Interfaces: NoSideEffect (MemoryEffectOpInterface), TflRuntimeVerifyOpInterface

Effects: MemoryEffects::Effect{}

Operands:

Operand Description
input tensor of 64-bit signless integer or 32-bit signless integer or 32-bit float values

Results:

Result Description
output tensor of 64-bit signless integer or 32-bit signless integer or 32-bit float values
