SSDLite量化说明

在SSDLite模型中我们采用完整量化训练的方式对模型进行训练,在8卡GPU下共训练40万轮,训练中将res_conv1se_block固定不训练,执行指令为:

python slim/quantization/train.py --not_quant_pattern res_conv1 se_block \
        -c configs/ssd/ssdlite_mobilenet_v3_large.yml \
        --eval

YOLOv3剪裁说明

首先对YOLO检测头进行剪裁,然后再使用 YOLOv3-ResNet34 作为teacher网络对剪裁后的模型进行蒸馏, teacher网络在COCO上的mAP为31.4 (输入大小320*320).

可以使用如下两种方式进行剪裁:

  • 固定比例剪裁, 整体剪裁率是86%

    --pruned_params="yolo_block.0.0.0.conv.weights,yolo_block.0.0.1.conv.weights,yolo_block.0.1.0.conv.weights,yolo_block.0.1.1.conv.weights,yolo_block.0.2.conv.weights,yolo_block.0.tip.conv.weights,yolo_block.1.0.0.conv.weights,yolo_block.1.0.1.conv.weights,yolo_block.1.1.0.conv.weights,yolo_block.1.1.1.conv.weights,yolo_block.1.2.conv.weights,yolo_block.1.tip.conv.weights,yolo_block.2.0.0.conv.weights,yolo_block.2.0.1.conv.weights,yolo_block.2.1.0.conv.weights,yolo_block.2.1.1.conv.weights,yolo_block.2.2.conv.weights,yolo_block.2.tip.conv.weights" \
    --pruned_ratios="0.75,0.75,0.75,0.75,0.75,0.75,0.75,0.75,0.75,0.75,0.75,0.75,0.875,0.875,0.875,0.875,0.875,0.875"
  • 使用 FPGM 算法剪裁:

    --prune_criterion=geometry_median
