How to slice multiple spans from a big 1D tensor ...
https://discuss.pytorch.org/t/how-to-slice-multiple-spans-from-a-big-1d-tensor...
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 …

How to normalize a tensor in PyTorch?
https://www.tutorialspoint.com/how-to-normalize-a-tensor-in-pytorch
A tensor in PyTorch can be normalized using the normalize() function provided in the torch.nn.functional module. This is a non-linear activation function. It performs Lp normalization of a given tensor over a specified dimension.. It returns a tensor of normalized value of the elements of original tensor.

Conv1d — PyTorch 1.10.1 documentation
https://pytorch.org/docs/stable/generated/torch.nn.Conv1d.html
At groups=1, all inputs are convolved to all outputs. At groups=2, the operation becomes equivalent to having two conv layers side by side, each seeing half the input channels and producing half the output channels, and both subsequently concatenated. At groups= in_channels, each input channel is convolved with its own set of filters (of size.
