Pytorch max index
Webtorch.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 … WebMar 28, 2024 · for finding index of an element in 1d tensor/array Example mat=torch.tensor ( [1,8,5,3]) to find index of 5 five=5 numb_of_col=4 for o in range (numb_of_col): if mat [o]==five: print (torch.tensor ( [o])) To find element index of a 2d/3d tensor covert it into 1d #ie example.view (number of elements) Example
