12.03.2019 · I think pytorch here is following same numpy behaviour, as @albanD mentioned: 1- When a boolean tensor / array is passed to index, it will perform a mask behaviour. 2- Both in pytorch and numpy, when providing a Python List it will assume as coordinates to grab:
torch.index_select — PyTorch 1.10.1 documentation
https://pytorch.org/docs/stable/generated/torch.index_select.html
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 …

Tensor Indexing API¶. Indexing a tensor in the PyTorch C++ API works very similar to the Python API. All index types such as None / ... / integer / boolean / slice / tensor are available in the C++ API, making translation from Python indexing code to C++ very simple. The main difference is that, instead of using the []-operator similar to the Python API syntax, in the C++ API the indexing ...

07.04.2020 · Advanced indexing in pytorch works just as NumPy's, i.e the indexing arrays are broadcast together across the axes. So you could do as in FBruzzesi's answer. Though similarly to np.take_along_axis, in pytorch you also have torch.gather, to take values along a specific axis: x.gather (1, y.view (-1,1)).view (-1) # tensor ( [1, 6, 8])

PyTorch中的index_select选择函数 - 知乎专栏
https://zhuanlan.zhihu.com/p/329104226
由于 index_select 函数只能针对输入张量的其中一个维度的一个或者多个索引号进行索引,因此可以通过 PyTorch 中的高级索引来实现。 获取 1D 张量 a 的第 1 个维度且索引号为 2 和 3 的张量子集: torch.index_select(a, dim = 0, index = torch.tensor([2, 3]))a[[2, 3]];
