Ich versuche, eine RESNET mit keras zu trainieren, tensorflow
Das Modell war ich mit ResNet50 istTypeerror: Objekt .__ neue __ (_ hashlib.HASH) nicht sicher ist, verwenden Sie _hashlib.HASH .__ neue __()
I habe diese Fehlermeldung wenn ich einen Keras Checkpoint zu meinem Trainingsprozess hinzufüge.
Hier ist mein Code:
def train(batch_size, nb_classes = 5):
x_train, y_train, x_test, y_test = loadData(nb_classes)
x_train = (x_train.astype(np.float32) - 127.5)/127.5
x_test = (x_test.astype(np.float32) - 127.5)/127.5
r_model =model(nb_classes,dropout= True)
model = multi_gpu_model(r_model, gpus=4)
optim = SGD(lr=0.00001, decay=1e-6, momentum=0.9, nesterov=True)
model.compile(loss='categorical_crossentropy', optimizer = optim,metrics=['accuracy'])
model.load_weights('/../weights1',True)
checkpointer = ModelCheckpoint(filepath='/.../weights2', save_best_only=True)
model.fit(x_train, y_train, epochs=10, batch_size=128,validation_data=(x_test, y_test),shuffle=True,callbacks=[checkpointer])
Das Programm stürzt ab, wenn ich diese Zeile hinzu:
checkpointer = ModelCheckpoint(filepath='/.../weights2', save_best_only=True)
ich im Internet gesucht, ich glaube, es hat etwas mit deepcopy in einigen Funktionen sein muss, habe ich .
Aber wie kann ich es beheben?
Die Fehlermeldung:
