Just need a way to handle the case where more than 1 integer is given, like in the third row of the above example. Learn how to use torch.index_select to index a tensor along a dimension using a longtensor of indices. “how can i choose elements from tensor a following the.
pytorch中的一些函数torch.cat()、index_select()、torch.gather()_torch.cat中dim
In some situations, you’ll have to do some advanced indexing / selection with pytorch, e.g. Indices = torch.tensor([0, 2]) selected_rows = torch.index_select(tensor, 0, indices) print(selected_rows) Torch.index_select(b, 0, a[:, 0]) almost gives the correct answer.
I’m trying to write my own index_select to understand how this is done under the hood efficiently.
In pytorch, the.index_select() function extracts specific elements from a tensor along a specified dimension based on indices and returns a new tensor. The following are 30 code examples of torch.index_select (). See the parameters, return value and a simple example code snippet. We call torch.index_select with x as the input tensor, dim=0 to select rows, and indices to specify which rows to select.
Index_select (dim, index) → tensor ¶ see torch.index_select() Use this to pick entire rows or columns. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the. Suppose we have access to index(t, indices) where passing a list of raw.

Torch.index_select(input, dim, index, out=none) parameters:.
You can use the torch.index_select() function (or the tensor.index_select() method) to select multiple dimensions from a tensor and return a new tensor with the same number of. Torch.index_select torch.index_select(input, dim, index, *, out=none) → tensor. How these work and can be used to embed words with word vectors in a. Returns a new tensor which indexes the input tensor along dimension dim using the entries in index which is.
A tensor is returned with indices as mentioned, by selecting from the target tensor. We define indices as a 1d tensor containing 0 and 2, indicating we want.
