Does the VitDet still adopt FPN rather than the simple pyramid structure in VITDet paper?

In the config file https://github.com/ViTAE-Transformer/ViTDet/blob/main/configs/ViTDet/ViTDet-ViT-Base-100e.py, It seems that the VitDet in your implementation still adopts the FPN modules rather than the simple pyramid structure as proposed in VitDet paper.

Hi, we modify the FPN file with an extra option use_residual=False to disable the residual connection in the FPN module, which only serves for feature dimension change, as described in the simple pyramid structure.
