錯誤朱古力的prototxt，caffe.SolverParameter沒有名爲「名」

Question

我寫了使用HDF5關於多標籤分類的朱古力淨場，這裏被命名爲「auto_train.prototxt」

的prototxt文件這就是train.sh

./build/tools/caffe train \ 
-solver examples/corel5k/auto_train.prototxt \ 
-weights examples/corel5k/bvlc_reference_caffenet.caffemodel 

但是當我運行該腳本，它得到了一些錯誤

我不知道發生了什麼，尋求幫助

Answer 1

您是與解算器定義prototxt（a.k.a solver.prototxt）混亂的網狀結構定義prototxt（a.k.a train_val.prototxt）。

參見例如AlexNet example這兩個不同的原型文件。

網狀結構的定義，train_val.prototxt定義了網絡結構，看起來就像auto_train.prototxt文件，你寫的。

但是，您錯過了爲優化過程定義元參數的solver definition prototxt,solver.prototxt。
在你的情況下，solver.prototxt會看起來像：

net: "examples/corel5k/auto_train.prototxt" # here is where you put the net structure file 
test_iter: 1000 
test_interval: 1000 
base_lr: 0.01 
lr_policy: "step" 
gamma: 0.1 
stepsize: 100000 
display: 20 
max_iter: 450000 
momentum: 0.9 
weight_decay: 0.0005 
snapshot: 10000 
snapshot_prefix: "examples/corel5k/my_auto_snapshots" 
solver_mode: GPU 

你可以找到關於如何設置參數元在solver.protoxthere和here信息。

一旦你有一個適當的solver.prototxt可以運行朱古力：

./build/tools/caffe train \ 
    -solver examples/corel5k/solver.prototxt \ 
    -weights examples/corel5k/bvlc_reference_caffenet.caffemodel
