1：caffe 目录下运行：scripts/download_model_binary.py models/bvlc_reference_caffenet
2：mkdir examples/_temp
3：find `pwd`/examples/images -type f -exec echo {} \; > examples/_temp/temp.txt
4：sed "s/$/ 0/" examples/_temp/temp.txt > examples/_temp/file_list.txt
5：./data/ilsvrc12/get_ilsvrc_aux.sh
6：cp examples/feature_extraction/imagenet_val.prototxt examples/_temp
7：./build/tools/extract_features.bin models/bvlc_reference_caffenet/bvlc_reference_caffenet.caffemodel examples/_temp/imagenet_val.prototxt fc7 examples/_temp/features 10 leveldb
结果存在examples/_temp/features下
