Split - version 1#

This page documents version 1 of operator Split. See Split for the latest version (since version 18).

  • Domain: ai.onnx

  • Since version: 1

Split a tensor into a list of tensors, along the specified ‘axis’. The lengths of the split can be specified using argument ‘axis’ or optional second input blob to the operator. Otherwise, the tensor is split to equal sized parts.

Inputs

  • input (T): The tensor to split

  • split (T): Optional list of output lengths (see also arg ‘split’)

Outputs

Between 1 and ∞ outputs.

  • outputs… (T): One or more outputs forming list of tensors after splitting

Attributes

  • axis (int): Which axis to split on

  • split (int[]): length of each output

Type Constraints

  • T: Constrain input types to float tensors. Allowed types: tensor(double), tensor(float), tensor(float16).
