我装了paddle1.7版本，又重新拉了最新的PaddleDetection （release/0.2）代码， 运行指令：

python3 slim/quantization/train.py --not_quant_pattern slim_output --eval --c ./configs/ssd/ssd_mobilenet_v1_voc.yml -o max_iters=30000 save_dir=./output/mobilenetv1_slim LearningRate.base_lr=0.0001 LearningRate.schedulers="[!PiecewiseDecay {gamma: 0.1, milestones: [10000]}]" pretrain_weights=https://paddlemodels.bj.bcebos.com/object_detection/ssd_mobilenet_v1_voc.tar

出现报错信息：

缺少quant_weight_only键值？ 这个键值在哪里配置的？我是在/usr/local/lib/python3.5/dist-packages/paddleslim/quant/quanter.py的_quant_config_default（line 34 ）参数里加了了一行 'quant_weight_only'：'True'，出现如下报错，看错误应该还是一样的问题：
