Python — Тонко настроенная модель keras .h5 для модели .pb, используемая в c ++, дает ошибку при запуске модели

Я точно настроил модель VGG16 и сохранил модель с лучшей точностью. Мой код keras —

#Input size
rows = 125
column = 125

channels = 3 #RGB

#Resizing

def read_images(src):
#read every image and resize every image to same size
img = Image.open(src)
#print(img.size)
#method = Image.NEAREST if img.size == (rows,column) else Image.ANTIALIAS
im_rz = img.resize((rows,column), Image.ANTIALIAS)
#im_rz = resize_image_to_square(img, new_size = (rows,column))
#im_rz = ImageOps.fit(img, (rows,column), method = method)
return im_rz

#Conversion of image to np

l = LabelEncoder()
y_all = l.fit_transform(y_all)
y_all = np_utils.to_categorical(y_all)

#print(l.classes_)
#x_train, x_valid, y_train, y_valid = test_train_split(x_all, y_all, test_size = 0.2, random_state = 42, stratify = y_all)

x_train, x_test, y_train, y_test = train_test_split(x_all, y_all, test_size = 0.2, random_state = 42, stratify = y_all)

batch_size = 32
nb_classes = 3
epochs = 300

x_train = np.array(x_train).astype('float32')
x_test = np.array(x_test).astype('float32')
y_train = np.array(y_train).astype('float32')
y_test = np.array(y_test).astype('float32')

x_train /= 255.
x_test /= 255.

#model

vgg = VGG16(weights='imagenet', include_top=False, input_shape=(125, 125, 3))

# Freeze the layers except the last 4 layers
for layer in vgg.layers[:-4]:
layer.trainable = False

# Check the trainable status of the individual layers
for layer in vgg.layers:
print(layer, layer.trainable)

model = Sequential()

# Add the vgg convolutional base model
model.add(vgg_conv)

# Add new layers
model.add(layers.Flatten())
model.add(layers.Dense(1024, activation='relu'))
model.add(layers.Dropout(0.5))
model.add(layers.Dense(3, activation='softmax'))

print(model.summary())opt = keras.optimizers.RMSProp(lr=1e-4)

# #Training the model using optimizer

model.compile(loss='categorical_crossentropy',optimizer=opt,metrics=['accuracy'])

#Save the best model obtained during training

#from keras.callbacks import ReduceLROnPlateau
#lr_reduce = ReduceLROnPlateau(monitor='val_acc', factor=0.1, epsilon=0.0001, patience=1, verbose=1)

filepath = "weights.h5"checkpoint = ModelCheckpoint(filepath, monitor='val_acc', verbose=0, save_best_only=True, mode='max')
callbacks_list = [checkpoint]

#data generation and fitting

data_generation = ImageDataGenerator(
rotation_range = 45, #Makes sense to keep the rotation between 0 and 10, we don't want to rotate it a lot
width_shift_range = 0.0,
height_shift_range = 0.0,
horizontal_flip=True, #Random rotations, might help
vertical_flip=True,
zoom_range = 0.15
)

#data_generation.fit(x_train)#Model fitting!

#tbCallBack = keras.callbacks.TensorBoard(log_dir="./Graph", histogram_freq = 0, write_graph = True, write_images = True)
#callbacks_list.append(tbCallBack)

model_param=model.fit_generator(data_generation.flow(x_train, y_train,batch_size=batch_size),
steps_per_epoch=x_train.shape[0] // batch_size,
epochs=epochs,
validation_data=(x_test, y_test),
validation_steps=x_test.shape[0],
callbacks=callbacks_list)

Это краткое изложение модели

Я использовал этот скрипт для преобразования его из .h5 в файл .pb для использования в C ++.
https://github.com/bitbionic/keras-to-tensorflow/blob/master/k2tf_convert.py

Я использовал код C ++, похожий на этот код —
https://github.com/bitbionic/keras-to-tensorflow/blob/master/main.cpp

При выполнении кода на C ++ я получаю следующую ошибку:

Running model failed: Invalid argument: Matrix size-incompatible: In[0]: [1,1152], In[1]: [4608,512]
[[Node: dense_1/MatMul = MatMul[T=DT_FLOAT, transpose_a=false, transpose_b=false, _device="/job:localhost/replica:0/task:0/cpu:0"](flatten_1/Reshape, dense_1/kernel/read)]]

Как я могу удалить эту ошибку, а также файл pb создается неправильно?
