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 the …

31.12.2021 · I have a big 1D tensor A, which contains around 20M elements.I also have some spans with unequal lengths, i.e., B=[(s_1, e_1), (s_2, e_2), ..., (s_n, e_n)], where n may be more than 8K. The one-time slicing A[s:e] is very fast, but slicing for all spans in B by for loop is very time consuming. Is there any way to slice parallelly on gpu? My torch version is 1.8.1, and some …
