Versioned name: Unsqueeze-1
Category: Shape manipulation
Short description: Unsqueeze adds dimensions of size 1 to the first input tensor. The second input value specifies a list of dimensions that will be inserted. Indices specify dimensions in the output tensor.
Attributes: Unsqueeze operation doesn't have attributes.
Inputs:
- 1: Multidimensional input tensor of type T. Required.
- 2: OD or 1D tensor of type T_SHAPE with dimensions indices to be set to 1. Values could be negative. Required.
Types
- T: supported type.
- T_SHAPE: supported integer type.
Example
Example 1:
<layer ... type="Unsqueeze">
<input>
<port id="0">
<dim>2</dim>
<dim>3</dim>
</port>
</input>
<input>
<port id="1">
<dim>2</dim>
</port>
</input>
<output>
<port id="2">
<dim>1</dim>
<dim>2</dim>
<dim>3</dim>
<dim>1</dim>
</port>
</output>
</layer>
Example 2: (unsqueeze 0D tensor (constant) to 1D tensor)
<layer ... type="Unsqueeze">
<input>
<port id="0">
</port>
</input>
<input>
<port id="1">
<dim>1</dim>
</port>
</input>
<output>
<port id="2">
