“数组形状不正确。” 从npy转换为binaryproto时出错

Question

I have brainwash_mean.npy file and it is a correct file with no error.

I am trying to convert the npy file to binaryproto and I have 'Incorrect array shape.' error.

My code is

def convert_numpy_binaryproto(filename):
    print filename;
    avg_img = np.load(filename);
    #avg_img is your numpy array with the average data 
    blob = caffe.io.array_to_blobproto( avg_img);
    with open( mean.binaryproto, 'wb' ) as f :
        f.write( blob.SerializeToString())


def main(argv):
    convert_numpy_binaryproto(sys.argv[1]);


if __name__ == "__main__":
   main(sys.argv[1:])

What could be wrong?

Answer 1

The following code worked for me.

def convert_numpy_binaryproto(path):
    print path;
    avg_img = np.load(path);
    #avg_img is your numpy array with the average data 
    blob = caffe.proto.caffe_pb2.BlobProto();
    blob.channels, blob.height, blob.width = avg_img.shape;
    blob.data.extend(avg_img.astype(float).flat);
    binaryproto_file = open('mean.binaryproto', 'wb' );
    binaryproto_file.write(blob.SerializeToString());
    binaryproto_file.close();
