aistudio上训练了pp-yolo模型作为teacher模型，进行剪枝蒸馏训练，报错YOLOv3 output layer number not equal target number。 训练代码：

%cd /home/aistudio/work/PaddleDetection
!python slim/extensions/distill_pruned_model/distill_pruned_model.py \
        -c ./configs/yolov3_mobilenet_v1.yml \
        -t ./configs/ppyolo/ppyolo.yml \
        --teacher_pretrained=output/ppyolo/best_model \
        --pruned_params "yolo_block.0.0.0.conv.weights,yolo_block.0.0.1.conv.weights,yolo_block.0.1.0.conv.weights" \
        --pruned_ratios="0.2,0.3,0.4" \
        -o use_fine_grained_loss=true pretrain_weights=https://paddlemodels.bj.bcebos.com/object_detection/yolov3_mobilenet_v1_voc.tar
