测试Caffe的Alexnet caffe模型时出错-Java 学习之路

我用更高效的模型训练了caffe的Alexnet模型进行测试 . 由于我的训练是针对行人，我的图像大小是64 x 80图像 . 我对原型文件进行了更改以匹配我训练的图像大小 . 根据这个tutorial，最好将卷积滤波器大小设置为与输入图像大小相匹配 . 因此，我的过滤器大小与原始的Alexnet 's provided prototxt files (I trained and tested with Alexnet' s原始prototxt文件略有不同，并在下面提到的同一行中得到相同的错误 .

根据我的计算，通过每一层后的图像尺寸将是

80x64x3 - > Conv1 - > 38x30x96
38x30x96 - >池 - > 18x14x96
18x14x96 - > Conv2 - > 19x15x256
19x15x256 - > Pool2 - > 9x7x256
9x7x256 - > Conv3 - > 9x7x384
9x7x384 - > Conv4 - > 9x7x384
9x7x384 - > Conv5 - > 9x7x256
9x7x256 - > Pool5 - > 4x3x256

错误位于 test_predict_imagenet.cpp 的fc6层和行号714处 . 我使用 test_predict_imagenet.cpp 文件来测试模型 .

CHECK_EQ(target_blobs[j]->width(), source_layer.blobs(j).width());

错误是

F0816 22:58:28.328047  3432 net.cpp:714] Check failed: target_blobs[j]->width()
== source_layer.blobs(j).width() (5120 vs. 1024)

我不明白为什么会这样 .

我的两个原型文件如下所示 .
