PyTorch Tensor
? Similar to NumPy arrays ? They can also be used on a GPU
? Faster computation
import torch x = torch.zeros(5, 3)
? All zeros ? Directly from data ? Size of a tensor
x = torch.tensor([5.5, 3]) print x.size()

x = torch.randn(4, 4) y = torch.randn(4, 4)
print(torch.add(x, y))
print(x[:, 1])

? Resizing
? If you want to resize/reshape tensor
x = torch.randn(4, 4)
y = x.view(16) z = x.view(-1, 8)
9/25/2020
print(x.size(), y.size(), z.size())
Output:
torch.Size([4, 4]) torch.Size([16]) torch.Size([2, 8])
