Question
what is the result of the following:123A = torch.tensor([[0, 1, 1], [1, 0, 1]])B = torch.tensor([[1, 1], [1, 1], [-1, 1]])A_times_B = torch.mm(A,B)1 pointtensor([[0, 2], [0, 2]])tensor([[0, 1], [1, 4]])
Solution
The result of the multiplication of tensors A and B (A_times_B) is a new tensor. The multiplication is done using the torch.mm function, which performs a matrix multiplication of the two tensors.
Here are the tensors:
A = torch.tensor([[0, 1, 1], [1, 0, 1]]) B = torch.tensor([[1, 1], [1, 1], [-1, 1]])
The multiplication is done as follows:
First row of A_times_B: (01 + 11 + 1*-1 , 01 + 11 + 1*1) = (0, 2)
Second row of A_times_B: (11 + 01 + 1*-1 , 11 + 01 + 1*1) = (0, 2)
So, A_times_B = torch.tensor([[0, 2], [0, 2]])
Therefore, the correct answer is tensor([[0, 2], [0, 2]]).

Machine ChallengeIn the Python file, write a PyTorch program to create a 2-dimensional tensor of size 3x3, filled with predefined random float numbers between 0 and 1. Set the seed for the random number generator in PyTorch to 0 using torch.manual_seed(0).Next, compute and print the sum of all the tensor elements. Finally, convert the tensor to a Python list and print it.Example Output:Sum of all tensor elements: 4.724854469299316[[0.7576315999031067, 0.2793108820915222, 0.40306925773620605], [0.7346844673156738, 0.029281556606292725, 0.7998586297035217], [0.3971373438835144, 0.7543719410896301, 0.5695084929466248]]
