cntk:to-sequence-with-lengths(
   $x as cntk:variable,
   $sequence-lengths as xs:variable,
   $sequence-axis-name-prefix as xs:string,
   $name as xs:string
) as cntk:function

Summary

Create an instance of the CNTK built-in operator for converting the specified tensor operand into a sequence This overload allows specifying an additional operand containing the lengths of individual sequences

Parameters
$x The tensor (or its name) which is converted to a sequence.
$sequence-lengths Optional tensor operand representing the sequence lengths. if unspecified, all sequences are assumed to be of the same length; i.e. dimensionality of the most significant static axis.
$sequence-axis-name-prefix
$name The name of the function instance in the network.

Example

  let $input-variable1 := cntk:input-variable(cntk:shape((2,2)), "float",
    fn:false(), fn:false(), "feature",(cntk:default-batch-axis()))
  let $input-variable2 := cntk:input-variable(cntk:shape((1)), "float",
    fn:false(), fn:false(), "feature",(cntk:default-batch-axis()))
  return cntk:to-sequence-with-lengths($input-variable1, $input-variable2,"")
  => cntk:function(Composite ToSequenceOp (Input(Name(feature), Shape([2 x 2]),
  Dynamic Axes([Batch Axis(Default Batch Axis)])), Input(Name(feature),
  Shape([1]), Dynamic Axes([Batch Axis(Default Batch Axis)]))))
