我目前正在閱讀'CMS-RCNN:基於上下文多尺度區域的CNN無約束人臉檢測'的論文,它使用skip-connection將conv3-3,conv4-3和conv5-3融合在一起,步驟如下所示基於Caffe中的VGG16製作跳躍層連接網絡時出錯
提取臉部區域的特徵映射(多個比例的conv3-3,conv4-3,conv5-3)並應用RoI - 回到它(即轉換爲固定的高度和寬度)。 L2-規格化每個特徵圖。 連接(RoI合併和歸一化)臉部(多個比例)的特徵映射(彼此)(創建一個張量)。 對臉部張量應用1x1卷積。 將兩個完全連接的層應用到面張量,創建一個向量。
我用朱古力並提出基於快RCNN VGG16一個prototxt以下的部位被添加到原prototxt在培訓期間
# roi pooling the conv3-3 layer and L2 normalize it

,我遇到了這樣一個問題
F0616 16:43:02.899025 3712 net.cpp:757] Cannot copy param 0 weights from layer 'fc6'; shape mismatch. Source param shape is 1 1 4096 25088 (102760448); target param shape is 4096 10368 (42467328). To learn this layer's parameters from scratch rather than copying from a saved net, rename the layer.
我可以找出哪裏出了問題,如果你能發現一些問題或解釋,我需要你的幫助。
真的很感謝!
