What does `-1` of `view ()` mean in PyTorch? - Stack Overflow

So a.view(-1,1) will result in a vector with the dimension 17x1 because there are 17 values - so v.view(1,-1) will result in a 1x17 vector.. . – Yuna Commented Jun 11, 2018 at 7:31

torch.Tensor.view — PyTorch 2.7 documentation

view (dtype) → Tensor. Returns a new tensor with the same data as the self tensor but of a different dtype.. If the element size of dtype is different than that of self.dtype, then the size of the last dimension of the output will be scaled proportionally.For instance, if dtype element size is twice that of self.dtype, then each pair of elements in the last dimension of self will be combined ...

What does .view(-1) do? - PyTorch Forums

The view(-1) operation flattens the tensor, if it wasn’t already flattened as seen here:. x = torch.randn(2, 3, 4) print(x.shape) > torch.Size([2, 3, 4]) x = x.view(-1) print(x.shape) > torch.Size([24]) It’ll modify the tensor metadata and will not create a copy of it.

How Does the "View" Method Work in Python PyTorch?

tensor.view(*shape) tensor: The original tensor you want to reshape. shape: The desired shape of the output tensor. This can be a tuple of integers or a series of comma-separated integers representing the new shape. Practical Examples of .view() in PyTorch Example 1: Basic Reshaping. Suppose you have a 2D tensor and want to reshape it into a 1D ...

Tensor Views — PyTorch 2.7 documentation

Typically a PyTorch op returns a new tensor as output, e.g. add(). But in case of view ops, outputs are views of input tensors to avoid unnecessary data copy. No data movement occurs when creating a view, view tensor just changes the way it interprets the same data. Taking a view of contiguous tensor could potentially produce a non-contiguous ...

python - What does `view ()` do in PyTorch? - Stack Overflow

view() reshapes the tensor without copying memory, similar to numpy's reshape(). Given a tensor a with 16 elements:. import torch a = torch.range(1, 16) To reshape this tensor to make it a 4 x 4 tensor, use:. a = a.view(4, 4) Now a will be a 4 x 4 tensor.Note that after the reshape the total number of elements need to remain the same.

PyTorch Tensor.view() method (with example) - Sling Academy

Where: self: The input tensor that you want to reshape. *shape: Either a torch.Size object or a sequence of integers that specify the desired shape of the output tensor. You can also use -1 to infer the size of a dimension from the other dimensions.; However, Tensor.view() only works on contiguous tensors, which are tensors that are stored in contiguous memory.
