Figure 1.4 - Tensors are just higher-dimensional matrices - make sure to check this version out :-)
You can create tensors in PyTorch pretty much the same way you create arrays in
Numpy. Using tensor() you can create either a scalar or a tensor.
PyTorch’s tensors have equivalent functions to its Numpy counterparts, like
ones(), zeros(), rand(), randn(), and many more. In the example below, we create
one of each: scalar, vector, matrix, and tensor—or, saying it differently, one scalar
and three tensors.
scalar = torch.tensor(3.14159)
vector = torch.tensor([1, 2, 3])
matrix = torch.ones((2, 3), dtype=torch.float)
tensor = torch.randn((2, 3, 4), dtype=torch.float)
print(scalar)
print(vector)
print(matrix)
print(tensor)
