Question 1

+2 marksOne correct option

You have a tensor x = torch.tensor([1, 2, 3, 4]).

You perform

python
stacked_x_dim0 = torch.stack([x, x, x], dim=0)

And

python
stacked_x_dim1 = torch.stack([x, x, x], dim=1)

What will be the shapes of stacked_x_dim0 and stacked_x_dim1 respectively?

  1. A

    stacked_x_dim0: [3, 3], stacked_x_dim1: [4, 4]

  2. B

    stacked_x_dim0: [4, 3], stacked_x_dim1: [3, 4]

  3. C

    stacked_x_dim0: [3, 4], stacked_x_dim1: [4, 3]

  4. D

    stacked_x_dim0: [4, 4], stacked_x_dim1: [3, 3]

Show answer
