I have two pytorch tensors: X with shape (A, B, C, D) I with shape (A, B) Values in I are integers in range [0, C). What is the most efficient way to get tensor Y ...

Dec 18, 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.

Here, the required library is torch. Define a PyTorch tensor. Access the value of a single element at particular index using indexing or access ...

torch.index_select — PyTorch 1.10.0 documentation 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 ).

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.

22.12.2021 · Pytorch Tensor get the index of specific value I think there is no direct translation from list.index() to a pytorch function. However, you can achieve similar results using tensor==number and then the nonzero() function.

index: indices of the tensor to select from. It can be LongTensor or IntTensor. tensor: tensor containing the values to add. Example 1: We take ...

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 …

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.

02.01.2022 · We don't know the shape of the input tensor and we shouldn't use any loops. Only reduction and indexing operations. How do we set the minimum value of each row to zero? For example: input: x = torch.

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.

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).

09.11.2018 · If I get you correctly you don't want the values, but the indices. Unfortunately there is no out of the box solution. There exists an argmax() function, but I cannot see how to get it to do exactly what you want.. So here is a small workaround, the efficiency should also be okay since we're just dividing tensors:

Sep 14, 2019 · This question already has answers here : How Pytorch Tensor get the index of specific value (8 answers) Closed 2 years ago. I have 2 Tensors named x and list and their definitions are below: x = torch.tensor (3) list = torch.tensor ( [1,2,3,4,5]) Now I want to get the index of element x from list. The expected output is an Integer:

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 ...

Aug 30, 2019 · To get a value from non single element tensor we have to be careful: The next example will show that PyTorch tensor residing on CPU shares the same storage as numpy array na. Example: Shared storage. import torch a = torch.ones ( (1,2)) print (a) na = a.numpy () na [0] [0]=10 print (na) print (a) Output:

tensor(Tensor): tensor containing values to add,Returns a new tensor which indexes the input tensor along dimension dim using the entries in ...

12.05.2020 · HI, torch uses same convention as numpy such for finding values or indices of particular tensor regarding specific condition. torch.where and torch.nonzero. 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 torch a = torch.randn(10) b = a <= 0 indices = b.nonzero()

Jan 04, 2022 · In this article, we will discuss tensor operations in PyTorch. PyTorch is a scientific package used to perform operations on the given data like tensor in python. A Tensor is a collection of data like a numpy array. We can create a tensor using the tensor function: This operation is used to expand ...
