torch.unsqueeze¶
- torch.unsqueeze(input, dim) Tensor ¶
Returns a new tensor with a dimension of size one inserted at the specified position.
The returned tensor shares the same underlying data with this tensor.
A
dim
value within the range[-input.dim() - 1, input.dim() + 1)
can be used. Negativedim
will correspond tounsqueeze()
applied atdim
=dim + input.dim() + 1
.- Parameters:
Example:
>>> x = torch.tensor([1, 2, 3, 4]) >>> torch.unsqueeze(x, 0) tensor([[ 1, 2, 3, 4]]) >>> torch.unsqueeze(x, 1) tensor([[ 1], [ 2], [ 3], [ 4]])
