unsqueeze¶

nvtripy.unsqueeze(input: Tensor, dim: int) → Tensor[source]¶

Returns a new tensor with the contents of the input tensor with a singleton dimension inserted before the specified axis.

Parameters:

input (Tensor) – The input tensor.
dim (int) – index before which to insert the singleton dimension. A negative dimension will be converted to dim = dim + input.rank + 1.

Returns:

A new tensor.

Return type:

Tensor

INPUT REQUIREMENTS:: input.dtype is one of [float32, float16, bfloat16, int8, int32, int64, bool]
OUTPUT GUARANTEES:: return[0].dtype == input.dtype

Example

input = tp.iota((2, 2), dtype=tp.float32)
output = tp.unsqueeze(input, 1)

Local Variables¶

>>> input
tensor(
    [[0, 0],
     [1, 1]], 
    dtype=float32, loc=gpu:0, shape=(2, 2))

>>> output
tensor(
    [[[0, 0]],

     [[1, 1]]], 
    dtype=float32, loc=gpu:0, shape=(2, 1, 2))
