J'ai formé le modèle Alexnet de caffe pour tester avec un modèle plus efficace. Puisque ma formation est pour les piétons, ma taille d'image est de 64 x 80 images. J'ai fait des changements aux fichiers prototxt pour correspondre à ma taille d'image formée. Selon ce tutorial, il vaudra mieux régler la taille du filtre de convolution pour qu'il corresponde à la taille de l'image d'entrée. Donc, mes tailles de filtres ont de légères modifications par rapport aux fichiers prototxt fournis par Alexnet d'origine (je les ai entraînés et testés avec les fichiers prototxt originaux d'Alexnet et j'ai obtenu la même erreur sur la même ligne mentionnée ci-dessous).Erreur dans le test du modèle caffe Alexnet de Caffe
Selon mon calcul, la taille d'image après le passage de chaque couche sera
80x64x3 -> CONV1 -> 38x30x96
38x30x96 -> Piscines -> 18x14x96
18x14x96 -> CONV2 -> 19x15x256
19x15x256 - > Pool2 -> 9x7x256
9x7x256 -> Conv3 -> 9x7x384
9x7x384 -> Conv4 -> 9x7x384
9x7x384 -> Conv5 -> 9x7x256
9x7x256 -> intérieure5 -> 4x3x256
L'erreur est sur la couche fc6 et le numéro de ligne 714 de test_predict_imagenet.cpp
. J'utilise le fichier test_predict_imagenet.cpp
pour tester le modèle.
CHECK_EQ(target_blobs[j]->width(), source_layer.blobs(j).width());
L'erreur est
F0816 22:58:28.328047 3432 net.cpp:714] Check failed: target_blobs[j]->width()
== source_layer.blobs(j).width() (5120 vs. 1024)
Je ne comprends pas pourquoi il est comme ça.
Mes deux fichiers prototxt sont présentés ci-dessous.
