torch.index_select(input, dim, index, *, out=None) → Tensor. Returns a new tensor which indexes the input tensor along dimension dim using the entries in index which is a LongTensor. The returned tensor has the same number of dimensions as the original tensor ( input ). The dim th dimension has the same size as the length of index; other dimensions have the same size as in the original tensor.

May 12, 2020 · What you can do is to apply your condition and get a binary mask of indices that match the condition and find the indices using torch.nonzero(). import torcha = torch.randn(10)b = a <= 0indices = b.nonzero() bests.

torch.where. Return a tensor of elements selected from either x or y, depending on condition. The operation is defined as: The tensors condition, x, y must be broadcastable. Currently valid scalar and tensor combination are 1. Scalar of floating dtype and torch.double 2. Scalar of integral dtype and torch.long 3.

12.07.2018 · I want to get the index of one thing in the other. I used to be converting it to python lists and work on that, but now I want to @script my function, and these list operations starts to become trouble. So I'm seeking for a neat pytorch solution.

torch.index_select¶ torch. index_select (input, dim, index, *, out = None) → Tensor ¶ Returns a new tensor which indexes the input tensor along dimension dim using the entries in index which is a LongTensor.. The returned tensor has the same number of dimensions as the original tensor (input).The dim th dimension has the same size as the length of index; other dimensions have …

In python list, we can use list.index(somevalue) . How can pytorch do this? For example: a=[1,2,3] print(a.index(2)). Then, 1 will be output.

Dec 18, 2017 · print ( (torch.abs ( (torch.max (your_tensor).item ()-your_tensor))<0.0001).nonzero ()) Here I want to get the index of max_value in the float tensor, you can also put your value like this to get the index of any elements in tensor. print ( (torch.abs ( (YOUR_VALUE-your_tensor))<0.0001).nonzero ()) Share.

18.12.2017 · For floating point tensors, I use this to get the index of the element in the tensor.. print((torch.abs((torch.max(your_tensor).item()-your_tensor))<0.0001).nonzero()) Here I want to get the index of max_value in the float tensor, you can also put your value like this to get the index of any elements in tensor.

I'm suggesting to add the following operator to pytorch: result = torch.find(tensor, from_) This operator outputs a long tensor of the same ...

19.11.2017 · I have a 1D Variable (LongTensor) and i want to find the indices of the elements with a given value (zero). Is there a way to do this efficiently in PyTorch? For instance, in order to get the indices of non-zero elements, i do this: non_zeros = torch.nonzero(lengths_c.view(-1).data).squeeze() I need the opposite of this (indices of zero elements).

29.05.2020 · In Py T orch we can access elements in a tensor by it’s index. If we have, for example a tensor with 3 rows and 3 columns, we can access the first element by the index (0, 0), the last element of...

12.07.2021 · Conditional GAN (cGAN) in PyTorch and TensorFlow. Our last couple of posts have thrown light on an innovative and powerful generative-modeling technique known as Generative Adversarial Network (GAN). Yes, the GAN story started with the vanilla GAN. But no, it did not end with the Deep Convolutional GAN.

由于 index_select 函数只能针对输入张量的其中一个维度的一个或者多个索引号进行索引，因此可以通过 PyTorch 中的高级索引来实现。 获取 1D 张量 a 的第 1 个维度且索引号为 2 和 3 的张量子集: torch.index_select(a, dim = 0, index = torch.tensor([2, 3]))a[[2, 3]]；
