Dec 03, 2020 · The tensor () method. This method returns a tensor when data is passed to it. data can be a scalar, tuple, a list or a NumPy array. In the above example, a NumPy array that was created using np.arange () was passed to the tensor () method, resulting in a 1-D tensor. We can create a multi-dimensional tensor by passing a tuple of tuples, a list ...

A NumPy array has been converted into a PyTorch Tensor. ... This function removes a dimension from a tensor and returns a tuple of slices of the tensor ...

torch.tensor_split. torch.tensor_split(input, indices_or_sections, dim=0) → List of Tensors. Splits a tensor into multiple sub-tensors, all of which are views of input , along dimension dim according to the indices or number of sections specified by indices_or_sections. This function is based on NumPy’s numpy.array_split ().

17.09.2020 · Motivation. (Note i already ask on pytorch forum but without luck, hope i m in the right place and you have time to have a look) The input of the decoder have the form List (List (Tensor)) where list have variable size and some dim of tensor is also dynamic. The output have the form Tuple (List (Tensor),List (Tensor)) where list have variable ...

24.05.2019 · I’m struggling to figure out how to do this, if it’s possible at all. I have a torchscript function that computes a tensor on each iteration. Because the tensors have different shapes, it’s not convenient to simply concatenate the tensors, so I’m collecting them in a list. Because only tuples can be returned from torchscript functions, I’m trying to convert the final list to a tuple ...

Use Tensor.tolist() e.g: >>> import torch >>> a = torch.randn(2, 2) >>> a.tolist() [[0.012766935862600803, 0.5415473580360413], ...

May 28, 2019 · to work as normal when observation is a single Tensor, and call .to (device) on each Tensor when observation is a tuple of Tensors. It should be simple enough to create a data type that can support this, but I'm wondering does such a data type already exist? I haven't found anything so far. pytorch Share Improve this question

Hello, I have a NN that has a gru and a resnet. The problem is that the output of the gru is a <class 'tuple'> but the resnet needs a tensor ...

03.12.2020 · PyTorch is an open-source Python-based library. It provides high flexibility and speed while building, training, and deploying deep learning models. At its core, PyTorch involves operations involving tensors. A tensor is a number, vector, matrix, or any n-dimensional array. In this article, we will see different ways of creating tensors

27.05.2019 · Expected observations are either state, as a 1 dimensional Tensor, or images as a 3 dimensional Tensor (channels, width, height). In my task I would like the observation to be a tuple of Tensors. In many places in my codebase, the observation is of course expected to be a single Tensor, not a tuple of Tensors.

07.02.2019 · Convert tuple to tensor without breaking graph. autograd. gshartnett (Gavin Hartnett) February 7, 2019, 3:43am #1. I want to be able to take the gradient of the norm-squared gradient of the loss function of a neural network. That’s a bit of a ...

14.07.2018 · is there a way to put tuple in tensor? e.g. FM = torch.ones(1,4,3,3) FM[0,0,1,1] = (2,2)

dims (int or Tuple[List, List] or List[List] containing two lists or Tensor) – number of dimensions to contract or explicit lists of dimensions for a and b respectively When called with a non-negative integer argument dims = d d d , and the number of dimensions of a and b is m m m and n n n , respectively, tensordot() computes

Jul 14, 2018 · is there a way to put tuple in tensor? e.g. FM = torch.ones(1,4,3,3) FM[0,0,1,1] = (2,2)

08.12.2021 · if you’re comparing to C++, List is like a vector<Tensor> of dynamic size, hence you cannot initialize specialized N-tuples from it, without runtime checks and metaprogramming anyway. Though I agree that TorchScript is lacking in some aspects, in this case the workaround is to return a list.

torch.as_tensor¶ torch. as_tensor (data, dtype = None, device = None) → Tensor ¶ Convert the data into a torch.Tensor.If the data is already a Tensor with the same dtype and device, no copy will be performed, otherwise a new Tensor will be returned with computational graph retained if data Tensor has requires_grad=True.Similarly, if the data is an ndarray of the corresponding …

torch.tensor_split. Splits a tensor into multiple sub-tensors, all of which are views of input , along dimension dim according to the indices or number of sections specified by indices_or_sections. This function is based on NumPy’s numpy.array_split (). If indices_or_sections is an integer n or a zero dimensional long tensor with value n ...

torch.as_tensor(data, dtype=None, device=None) → Tensor. Convert the data into a torch.Tensor. If the data is already a Tensor with the same dtype and device , no copy will be performed, otherwise a new Tensor will be returned with computational graph retained if data Tensor has requires_grad=True. Similarly, if the data is an ndarray of the ...

01.03.2019 · The tuple indexing means that we know exactly which part of the Tensor you’re using: this one entry. The list slicing can use arbitrary part of the Tensor as the slicing can be given any number of indices. In your particular case, I agree that the result is the same but the autograd engine is over-restrictive.
