Vision: It seems there is no upsampling operations in the implementation of Deeplabv3?

[songyuc]

Hi, guys,
I am learning about the the implementation of Deeplabv3 today,
and I find that it seems, there is no upsampling operations in deeplabv3.py,
so where is the upsampling operations of Deeplabv3 model?

Any answer or idea will be appreciated!

Hi,

The upsampling is present in the base class, see https://github.com/pytorch/vision/blob/819b2e9f39648711ab06562fc8f03ad001cf10be/torchvision/models/segmentation/_utils.py#L25
