Web22 de abr. de 2024 · Before 0.4.0. loss was a Variable wrapping a tensor of size (1,), but in 0.4.0 loss is now a scalar and has 0 dimensions. Indexing into a scalar doesn’t make sense (it gives a warning now, but will be a hard error in 0.5.0). Use loss.item () to get the Python number from a scalar. WebSwin Transformer (Shifted Window Transformer) can serve as a general-purpose backbone for computer vision. Swin Transformer is a hierarchical Transformer whose representations are computed with shifted windows. The shifted window scheme brings greater efficiency by limiting self-attention computation to non-overlapping local windows while also ...
