res101 inference result zero

[SuperPowerLF2]

看Owner是中国人就用中文了(小声BB...)

我直接用caffe.exe训练了 resnet101 (models/FRCNN/res101/solver.proto VOC2007)
我一开始训练了10000步发现推理结果为0 (使用test_frcnn.exe, 直接用训练集当做测试集)
于是我继续训练到20000发现推理结果还是为0
详细调试后发现score肥肠肥肠低都是0.00x,最高的我看到也就0.05...
我浏览了其他问题, 你说可以不用convert_model.py 于是我就直接训练完的模型直接test_frcnn也不行.输出结果如下

我现在不知道怎么修改了...下面是训练时一部分....我认为正常

请问如何修改使其能跑锕....救救我...

[makefile]

你的分类损失比较大，看起来不太正常。和另一个issue里边的问题一样，我很长时间不用这份代码了，也不好找出原因是什么。或许你换个proto再试试，或者换到我commit里边的历史版本，不清楚是不是因为我做了哪些改动造成的。

[SuperPowerLF2]

@makefile 还在苦战中, 寻找问题

[SuperPowerLF2]

@makefile 请问在哪里修改优化器类型, 原版在solver.proto type. 您的caffe在哪里改, 还有我想添加自己的优化器能不能帮我指条明路

[makefile]

@SuperPowerLF2 优化器类型也是在solver.proto里边指定，优化器的自定义可以在sgd_solver.cpp里边改。

[SuperPowerLF2]

@makefile 谢谢!

[SuperPowerLF2]

@makefile 我发现训练的成品(caffemodel), BN层gamma, beta,mean 里有参数! 可是我明明设置了 param {
lr_mult: 0
decay_mult: 0
}
x3
三个参数都是设置了, 你觉得是不是这个原因导致的
我网上找不到使用BN的预训练模型, 只能问问你...

[makefile]

@SuperPowerLF2 设置为0表示固定初始参数不变，不进行学习。
