about Cube struct

[zys1994]

Cube cls;
        Cube reg;
        Cube pts;

        // get blob output
        char clsname[100]; sprintf(clsname, "face_rpn_cls_prob_reshape_stride%d", _feat_stride_fpn[i]);
        char regname[100]; sprintf(regname, "face_rpn_bbox_pred_stride%d", _feat_stride_fpn[i]);
        char ptsname[100]; sprintf(ptsname, "face_rpn_landmark_pred_stride%d", _feat_stride_fpn[i]);

        net.Extract(nc, clsname, cls);
        net.Extract(nc, regname, reg);
        net.Extract(nc, ptsname, pts);
```when i use caffe C++, i find Cube not defined. Can you show me its structure？

[Charrin]

if you use caffe, replace cube to "caffe:Blob"

mxnet 如何替换，有没有提示性质的建议

[Charrin]

参考mxnet c++接口的例子

@Charrin @dwjlw1314 @zys1994 What is Cube? is it C++ class?
