torch.Tensor.expandaligns existing input dimensions with the trailing dimensions of the requested shape when new leading dimensions are introduced. The Torch frontend previously resolved-1using the output dimension index directly. For an input shaped(tokens, 3),x.expand(2, -1, -1)thus selected the wrong input dimensions and eventually accessed beyond the input rank.This PR:
-1-1for new leading dimensions, matching PyTorch semantics.=
