Pytorch Set Value By Index at Zane Steigrad blog

Pytorch Set Value By Index. Assigning a new value in the tensor will modify the tensor with the new value. Index_fill_ (dim, index, value) → tensor ¶ fills the elements of the self tensor with value value by selecting the indices in the order given. The objective is to set the value of the element with index 1,2 in the first row, 2,3 in the second row, and 3,5 in the third row of a to. Indexing a tensor in the pytorch c++ api works very similar to the python api. Assuming you would like to set the value at 99 to 1, this code should work and would avoid the loop: Because values has shape [3] you will want the two. We can access the value of a tensor by using indexing and slicing. Suppose i have a 2d index array of shape [b,1,n,2] i.e n points holding indexes on a target tensor of size [b,1,h,w]. Slicing is used to access the sequence of values in a tensor. Indexing is used to access a single value in the tensor. Index_select (input, dim, index, *, out = none) → tensor ¶ returns a new tensor which indexes the input tensor along dimension dim. All index types such as none /. T2 = torch.tensor( [[99, 2, 1, 3, 4],. We can modify a tensor by using the assignment operator. / integer / boolean / slice /.
