torch.Tensor.expand — PyTorch 1.10.0 documentation torch.Tensor.expand Tensor.expand(*sizes) → Tensor Returns a new view of the self tensor with singleton dimensions expanded to a larger size. Passing -1 as the size for a dimension means not changing the size of that dimension.

torch.Tensor.expand. Tensor.expand(*sizes) → Tensor. Returns a new view of the self tensor with singleton dimensions expanded to a larger size. Passing -1 as the size for a dimension means not changing the size of that dimension. Tensor can be also expanded to a larger number of dimensions, and the new ones will be appended at the front.

Jan 24, 2021 · I am trying to get a history of values of x with ‘for’ statement. For python floats, I get the expected list. The result is surprising with tensors: all entries of the list are the same! Please let me know why this happens with tensors. Thanks. — code — import torch # when x is a python float x_hist = [] x = 1.1 for i in range(3): x -= 0.1 x_hist.append(x) print(x_hist) # out [1.0, 0.9 ...

Is there a way of appending a tensor to another tensor in pytorch? I can use x = torch.cat((x, out), 0) for example, but it creates a new ...

May 04, 2017 · Is there a way of appending a tensor to another tensor in pytorch? I can use x = torch.cat((x, out), 0) for example, but it creates a new copy of x which is time-consuming.

31.10.2021 · You can concatenate the tensors along the specific dimension. Your question can be briefly expressed like below, a = torch.Size (1, 3, 7) b = torch.Size (1, 3, 7) result = torch.cat ( (a, b), dim=1) Then, you can get the result tensor size of (1, 6, 7) The sample code. for i in range (it): try: a = torch.cat ( (a, new_a), dim=1) except: a = new_a.

Assuming you're doing it in a loop, I'd say it is better to do like this: import torch batch_input, batch_output = [], [] for i in ...

Mar 08, 2019 · I don’t get it. S1 is a tensor. S2 is a tensor. Maybe you should copy paste the original task. If you have a problem with the number of steps, 15 steps in my solution and 16 you need you should consider starting from the empty tensor S2. I am novice in PyTorch. Sorry for the low quality answer.

20 timer siden · Using the PyTorch framework, this two-dimensional image or matrix can be converted to a two-dimensional tensor. In the previous post, we learned about one-dimensional tensors in PyTorch and applied some useful tensor operations. In this tutorial, we’ll apply those operations to two-dimensional tensors using the PyTorch library.

04.05.2017 · Is there a way of appending a tensor to another tensor in pytorch? I can use x = torch.cat((x, out), 0) for example, but it creates a new copy of x which is time-consuming. Thanks!

Dec 23, 2020 · In python, I can use: A = [1,2] B = 3 A.append(B) to get [1,2,3]. However, In pytorch, A = torch.tensor([1,2]) B = torch.tensor(3) How to get: tensor([1,2,3]) Thank you very much

24.01.2021 · In the case of tensor, xis a reference to the tensor. When we append it to the list, the reference is appended (not the value). Hence, when you modify xlater in-place (x -= 0.1) and print the elements in the list later, they all print the same (latest) value of x. yhpknu(Young Ho Park) January 24, 2021, 2:13am #3

torch.Tensor.add — PyTorch 1.10.1 documentation torch.Tensor.add Tensor.add(other, *, alpha=1) → Tensor Add a scalar or tensor to self tensor. If both alpha and other are specified, each element of other is scaled by alpha before being used. When other is a tensor, the shape of other must be broadcastable with the shape of the underlying tensor

torch.Tensor.index_add_. Accumulate the elements of alpha times tensor into the self tensor by adding to the indices in the order given in index. For example, if dim == 0, index [i] == j, and alpha=-1, then the i th row of tensor is subtracted from the j th row of self. The dim th dimension of tensor must have the same size as the length of ...
