13.01.2022 · Let’s say I have a tensor a = torch.tensor(([0,1,2],[3,4,5])). I have another tensor, b = torch.tensor([0,1]), that I want to use to index a, such that we obtain the 0th position of the first row, 1st position of the second row (resulting tensor is [0, 3]). How can this be done? It’s not the same as index_select, which finds the 0th and 1st positions for every row. Thanks!

Jul 12, 2018 · result = torch. find ( tensor, from_) This operator outputs a long tensor of the same shape as the argument tensor, where the result [i,j,..] is the first index at vector from_ whose value is the same as tensor [i,j,..]. For example: a = torch. tensor ( [ 0, 10, 20, 30 ]) b = torch. tensor ( [ [ 0, 30, 5 ], [ 20, 1, 0 ]]) torch. find ( b, a)

29.12.2018 · 在pytorch中，我们经常需要查找tensor中某一个元素的索引，可能是在向量中查找索引，也可能是在矩阵中查找索引，下面分贝举例子： 1.在矩阵中查找某个指定元素的索引： import torch import numpy as np a = torch.tensor( [[1,2,3],[4,5,6],[5,6,7],[6,7,8]] ) a_t2n = a.numpy() index = …

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

Indexing a Pytorch tensor is similar to that of a Python list. The pytorch tensor indexing is 0 based, i.e, the first element of the array has index 0. Accessing Tensor Elements. You can access an element from the Pytorch tensor by specifying the index of the element. Syntax: tensor_name[index] Example. In this example, we will be getting the ...

17.12.2017 · 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.

Pytorch – Index-based Operation · dim: dimension along which index to add. '0' stands for column and '1' stands for row. · index: indices of the ...

Does torch have a function that helps in finding the indices satisfying a condition? For instance, F = torch.randn(10) b = torch.index(F ...

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.

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).

Pytorch Tensor Indexing. Indexing in Pytorch is similar to that of numpy. The indexing is 0 based, i.e, the first element has 0 index.

I think there is no direct translation from list.index() to a pytorch function. However, you can achieve similar results using ...

Jul 18, 2021 · There are two types of index-based operations in PyTorch, one is in-place operations and the other is out-of-place operations. The basic difference between the two is in-place operation directly changes the values of the tensors without making any copy of that whereas out of place operations don’t. Following are the operations:- index_add_
