mrpro.utils.unsqueeze_left

mrpro.utils.unsqueeze_left(x: Tensor, n: int) → Tensor

Unsqueze multiple times in the leftmost dimension.

Example

tensor with shape (1,2,3) and n=2 would result in tensor with shape (1,1,1,2,3)

Parameters:

• x – tensor to unsqueeze

• n – number of times to unsqueeze

Return type:

unsqueezed tensor (view)
