06.04.2020 · Variables data, images, and targets are all of class tuple Traceback (most recent call last): File "train.py", line 40, in <module> images = images.to(device) AttributeError: 'tuple' object has no attribute 'to'

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 …

How can I convert tuple to tensor? ... 21 22 inputs = inputs.to(device) TypeError: expected Tensor as element 1 in argument 0, but got tuple.

torch.Size is in fact a tuple, so it supports the same operations ... LongTensor a = torch.full((10,), 3, device=torch.device("cuda")) print(type(a)) b ...

torch. as_tensor (data, dtype=None, device=None) → Tensor. Convert the data into a torch ... Can be a list, tuple, NumPy ndarray , scalar, and other types.

06.03.2021 · to()はデータ型dtypeの変更にも用いられる。 関連記事: PyTorchのTensorのデータ型（dtype）と型変換（キャスト） dtypeとdeviceを同時に変更することも可能。to(device, dtype)の順番だと位置引数として指定できるが、to(dtype, device)の順番だとキーワード引数として指定する必要があるので注意。

A tensor of specific data type can be constructed by passing a torch.dtype and/or a torch.device to a constructor or tensor creation op:.

8 images = images.to(device) 9 output = AE(images) 10 loss = loss_fn(output, images) # Here is a typical loss function (Mean square error).

You should open the for loop with as many items as your dataset returns at each iteration. Here is an example to illustrate my point:.

import torch torch.cuda.set_device(id) Pytoch中的in-place. in-place operation 在 pytorch中是指改变一个tensor的值的时候，不经过复制操作，而是在运来的内存上改变它的值。可以把它称为原地操作符。 在pytorch中经常加后缀 “_” 来代表原地in-place operation, 比如 .add_() 或者.scatter()

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 ...

03.07.2019 · h0 = torch.randn(self.num_layers2, int(x.size(0)), self.hidden_size).to(device) # 2 for bidirection c0 = torch.randn(self.num_layers2, int(x.size(0)), self.hidden_size).to(device). In this line you try to find the size of x, but x is a tuple I’m guessing.
