2 years ago I solved it. I think authors work lack a var of "cfg" in train_crfnet in line 134:
the previous line:
backbone_retinanet(num_classes, num_anchors=num_anchors, modifier=modifier, inputs=inputs, distance=distance),weights=weights, skip_mismatch=True, config=copy.deepcopy(cfg),num_classes=num_classes)
after modifying(add "cfg = cfg")
backbone_retinanet(num_classes, num_anchors=num_anchors, modifier=modifier, inputs=inputs, distance=distance, **cfg = cfg**), weights=weights, skip_mismatch=True, config=copy.deepcopy(cfg), num_classes=num_classes)

When multi_gpu=0, the network can be trained smoothly,
but when I change multi_gpu=8, I get the error bellow: It seems likely the cfg cannot be passed to backbone_retinanet. it seems like in train_crfnet.py line 131, backbone_retinanet(num_classes, num_anchors=num_anchors, modifier=modifier, inputs=inputs, distance=distance） cfg=cfg is missed
