torch ¶ The torch package ... index_select. Returns a new tensor which indexes the input tensor along dimension dim using the entries in index which is a LongTensor. masked_select. Returns a new 1-D tensor which indexes the input tensor according to the boolean mask mask which is a BoolTensor. movedim.

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).

torch.Tensor.select Tensor.select(dim, index) → Tensor Slices the self tensor along the selected dimension at the given index. This function returns a view of the original tensor with the given dimension removed. Parameters dim ( int) – the dimension to slice index ( int) – the index to select with Note select () is equivalent to slicing.

torch.gather(input, dim, index, out=None, sparse_grad=False) ... When you do x[_,:] or x[:, _] you select same index in every batch/feature.

torch.index_select ... Returns a new tensor which indexes the input tensor along dimension dim using the entries in index which is a LongTensor . The returned ...

torch.index_select(input,dim,index,out=None) The function returns a quantum set indexed along the specified index number of the specified ...

torch.masked_select(input, mask, *, out=None) → Tensor Returns a new 1-D tensor which indexes the input tensor according to the boolean mask mask which is a BoolTensor. The shapes of the mask tensor and the input tensor don’t need to match, but they must be broadcastable. Note The returned tensor does not use the same storage as the original tensor

torch.index_select ( input, dim, index, out=None) 函数返回的是沿着输入张量的指定维度的指定索引号进行索引的张量子集，其中输入张量、指定维度和指定索引号就是 torch.index_select ( input, dim, index, out=None) 函数的三个关键参数，函数参数有： input (Tensor) - 需要进行索引操作的输入张量； dim (int) - 需要对输入张量进行索引的维度； index (LongTensor) - 包含索引号的 …

25.03.2020 · torch.gather(input, dim, index, out=None, sparse_grad=False) → Tensor Gathers values along an axis specified by dim. So, it gathers values along axis. But how does it differ to regular indexing?...

torch.gather(input, dim, index, out=None, sparse_grad=False) → TensorGathers values along an axis specified by dim. 위와 같이 특정 인덱스를 ...

18.11.2017 · The only supported types are integers, slices, numpy scalars, or if indexing with a torch.LongTensor or torch.ByteTensor only a single Tensor may be passed. though numpy returns a (4, 2, 5) tensor successfully.

torch.masked_select. Returns a new 1-D tensor which indexes the input tensor according to the boolean mask mask which is a BoolTensor. The shapes of the mask tensor and the input tensor don’t need to match, but they must be broadcastable. input ( Tensor) – the input tensor. out ( Tensor, optional) – the output tensor.

(In R, negative indices are used to remove elements.) x <- torch_tensor(1:10) ...

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 ( …

(In R, negative indices are used to remove elements.) x <- torch_tensor(1:10) x[1] x[-1]. You can also subset matrices and higher dimensions arrays using ...

Nov 18, 2017 · Given a = torch.randn(3, 2, 4, 5), how I can select sub tensor like (2, :, 0, :), (1, :, 1, :), (2, :, 2, :), (0, :, 3, :) (a resulting tensor of size (2, 4, 5) or (4 ...

What you could do is flatten the first three axes together and apply torch.gather : >>> grid.flatten(start_dim=0, end_dim=2).shape torch.

torch.Tensor.select. Slices the self tensor along the selected dimension at the given index. This function returns a view of the original tensor with the given dimension removed. select () is equivalent to slicing. For example, tensor.select (0, index) is equivalent to tensor [index] and tensor.select (2, index) is equivalent to tensor [:,:,index].

Dec 31, 2018 · torch.index_select solves your problem more easily than torch.gather since you don't have to adapt the dimensions of the indeces. Indeces must be a tensor. For your case. indeces = [0,2] a = torch.rand (size= (3,3,3)) torch.index_select (a,dim=1,index=torch.tensor (indeces,dtype=torch.long)) Share. Improve this answer.
