.take()

The .take() function returns a 1D tensor containing elements from the given tensor at the specified indices. The resulting tensor will always be a 1D tensor irrespective of the size of the given tensor.

Syntax

torch.take(input,index)

• input: The input tensor from which the elements will be selected.
• index: A 1D tensor containing the indices of the elements to extract from input.

Example

The following example demonstrates the usage of .take() function:

import torch

# Define a tensor
data = torch.tensor([[4, 2, -1], [7, 8, 0]])

# Define indices as a tensor
indices = torch.tensor([0, 2, 5])

# Use torch.take with data and indices
result = torch.take(data, indices)
print(result)

The code produces the following output:

[4,-1,0]
