binaryproto转成.npy

https://www.zhihu.com/question/28102651/answer/39397649

io模块里面的blobproto_to_array，能够生成npy

用下面的代码在需要转换均值文件的目录下构建convert_protomean.py文件，然后调用

python convert_protomean.py mean.binaryproto cifar10_mean.npy

import caffeimport numpy as npimport sysif len(sys.argv) != 3:print "Usage: python convert_protomean.py proto.mean out.npy"sys.exit()blob = caffe.proto.caffe_pb2.BlobProto()data = open( sys.argv[1] , 'rb' ).read()blob.ParseFromString(data)arr = np.array( caffe.io.blobproto_to_array(blob) )out = arr[0]np.save( sys.argv[2] , out )
