Caffe ライブラリを使用して CSV ファイルから準備した HDF5 データを使用して、ニューラル ネットワークの最小限の例を構築しようとしています。
私のプロトテキストは次のとおりです: [wine_train.prototxt]
name:"wineclass"
layers {
name: "data"
type: "HDF5Data"
top: "data"
top: "label"
hdf5_data_param {
source: "examples/wine/test.txt"
batch_size: 10
}
include{
phase:TEST
}
}
layer {
name: "data"
type: "HDF5Data"
top: "label"
top: "label"
hdf5_data_param {
source: "examples/wine/train.txt"
batch_size: 2
}
include{
phase:TRAIN
}
}
layers {
name: "ip"
type: "INNER_PRODUCT"
bottom: "data"
top: "ip"
inner_product_param {
num_output: 3
}
}
layers {
name: "loss"
type: "SOFTMAX_LOSS"
bottom: "ip"
bottom: "label"
top: "loss"
}
layer {
name: "accuracy"
type: "Accuracy"
bottom: "ip"
bottom: "label"
top: "accuracy"
include {
phase: TEST
}
}
私のソルバーは次のとおりです。
net: "examples/wine/wine_train.prototxt"
test_iter: 250
test_interval: 1000
base_lr: 0.01
lr_policy: "step"
gamma: 0.1
stepsize: 5000
display: 1000
max_iter: 10000
momentum: 0.9
weight_decay: 0.0005
snapshot: 10000
snapshot_prefix: "wine/train"
solver_mode: CPU

エラーの正確な内容と解決方法を教えてください。
アップデート
これは実行されるようです:
name: "WineNet"
layer {
name: "data"
type: "HDF5Data"
top: "wine_train_data"
top: "wine_train_label"
hdf5_data_param {
source: "examples/wine/train.txt"
batch_size: 10
}
}
layer {
name: "fc1"
type: "InnerProduct"
bottom: "wine_train_data"
top: "fc1"
inner_product_param {
num_output: 2
}
}
layer {
name: "loss"
type: "SoftmaxWithLoss"
bottom: "fc1"
bottom: "wine_train_label"
top: "loss"
}

実質的に同一のモデル: 一方は動作しますが、他方は動作しません。理由は説明できません!
