事前にトレーニングしたカフェモデルをラザニアにロードしますか？

Question

Long-term Recurrent Convolutional Networks紙を再現しようとしています。

私はtheanoで使用したいと思う事前トレーニングされたカフェモデルを持っています。 私はこのファイルに.caffemodel、prototxtを持っています。 私はlasagne exampleを使って、カフェウェイトをカフェモデルにロードしました。 これはcode I usedですが、データはラセーンモデルに読み込まれません。 このエラーをスローするlasagne.layers.get_all_param_values(net)コマンドを使用してチェックします。

Answer 1

試み：

X = lasagne.layers.get_all_param_values（正味[ 'PROB']）

又はこの方法であなたのネットを作る：

def build_model(): 
    net = {} 
    # Input layer 
    net = InputLayer((None, 3, 227, 227)) 
    # First Conv Layer 
    net = ConvLayer(net, num_filters=96,filter_size=7, pad=0,  flip_filters=False,stride=2,nonlinearity=rectify) 
    net = PoolLayer(net, pool_size=3,stride=2,mode='max') 
    .... 
    net= NonlinearityLayer(net, softmax) 
    return net
