我有一个caffe“检查失败”错误:
...

你可以告诉我为什么“检查失败”?
什么“kernel_size指定2次; 0空间变暗”是指?
num_spatial_axes_ kernel_size在这里? 抱歉,如果我的问题很简单。
答案 0 :(得分:1)
查看图层的输入("ReLU0"
):
I0415 15:35:30.497133 39410 net.cpp:129] Top shape: 1 4096 (4096)
它的尺寸是1x4096,它有1个批次,4096个通道,没有宽度和没有高度(也就是说,宽度和高度是通常的单个尺寸忽略)。
现在您要应用"conv1"
1x5内核。你想如何在没有空间维度的blob上应用卷积?!
这是你从caffe得到的错误:你为conv内核指定了2个空间维度(你指定了kernel_size
两次),但你的输入blob根本没有空间维度,即num_spatial_axes_==0
。
