Model:
EfficientDet(
  (backbone): EfficientNetFeatures(
    (conv_stem): Conv2d(4, 48, kernel_size=(3, 3), stride=(2, 2), padding=(1, 1), bias=False)
    (bn1): BatchNorm2d(48, eps=0.001, momentum=0.1, affine=True, track_running_stats=True)
...
...

Is there a way to rename backbone  object to some other name?
