SplitToSequence

Description

Split a tensor into a sequence of tensors, along the specified β€˜axis’. Lengths of the parts can be specified using the optional argument β€˜split’. If the argumentΒ split'Β isΒ notΒ specified,Β aΒ defaultΒ scalarΒ valueΒ ofΒ 1Β isΒ usedΒ asΒ theΒ valueΒ ofΒ split’. β€˜split’ must contain only positive numbers. β€˜split’ is either a scalar (tensor of empty shape), or a 1-D tensor. If β€˜split’ is a scalar, then β€˜input’ will be split into chunks all of size β€˜split’ if possible. The last chunk alone may be smaller than β€˜split’ if the β€˜input’ size along the given axis β€˜axis’ is not divisible by β€˜split’. If β€˜split’ is a 1-dimensional tensor, the input tensor is split into β€˜size(split)’ chunks, with lengths of the parts on β€˜axis’ specified in β€˜split’. In this scenario, the sum of entries in β€˜split’ must be equal to the dimension size of input tensor on β€˜axis’.

 

Input parameters

 

specified_outputs_name :Β array, this parameter lets you manually assign custom names to the output tensors of a node.

Β Graphs in :Β cluster, ONNX model architecture.

input (heterogeneous) – T : object, the tensor to split.
split (optional, heterogeneous) –Β I : object, length of each output. It can be either a scalar(tensor of empty shape), or a 1-D tensor. All values must be >= 0.

Β Parameters :Β cluster,

axis: integer, which axis to split on. A negative value means counting dimensions from the back. Accepted range is [-rank, rank-1].
Default value β€œ0”.
keepdimsΒ :Β boolean, keep the split dimension or not. True, which means we keep split dimension. If input β€˜split’ is specified, this attribute is ignored.
Default value β€œTrue”.
Β training?Β :Β boolean, whether B should be transposed on the last two dimensions before doing multiplication.
Default value β€œTrue”.
Β lda coeff :Β float, defines the coefficient by which the loss derivative will be multiplied before being sent to the previous layer (since during the backward run we go backwards).
Default value β€œ1”.

Β name (optional) :Β string, name of the node.

Output parameters

 

output_sequence (heterogeneous) – S : object, one or more outputs forming a sequence of tensors after splitting.

Type Constraints

T in (tensor(bool),Β tensor(complex128),Β tensor(complex64),Β tensor(double),Β tensor(float),Β tensor(float16),Β tensor(int16),Β 
tensor(int32),Β tensor(int64),Β tensor(int8),Β tensor(string),Β tensor(uint16),Β tensor(uint32),Β tensor(uint64),Β tensor(uint8)) : Constrain input types to all tensor types.

I in (tensor(int32),Β tensor(int64)) : Constrain split size to integral tensor.
