Freeze the Backbone and Dilated Encoder

[ukdsvl]

Hi,

Many thanks for your awesome work. In the original Detectron2, we can freeze certain layers of the backbone with _C.MODEL.BACKBONE.FREEZE_AT.

Can you please let me know how to freeze both the ResNet backbone AND the Dilated Encoder, and update only the Decoder during training in YOLOF as well, say using yolof_R_50_C5_1x ?

You can manually add the freeze codes for backbone and encoder here in the yolof file as we do in the darknet.
