Question

我正在尝试将预训练的InceptionV3与this dataset上的keras一起使用。我拥有所有必要的进口商品：

import keras
from keras.applications.inception_v3 import InceptionV3
from keras.preprocessing import image
from keras.models import Model
from keras.layers import Dense, GlobalAveragePooling2D
from keras import backend as K

我正在这样做以创建和训练模型：

base_model = InceptionV3(weights='imagenet', include_top=False)

class_names = ["0", "1", "2", "3", "4"]

CLASSES = 5
x = base_model.output
x = GlobalAveragePooling2D(name='avg_pool')(x)
x = Dropout(0.4)(x)
predictions = Dense(CLASSES, activation='softmax')(x)
model = Model(inputs=base_model.input, outputs=predictions)

for layer in base_model.layers:
    layer.trainable = False


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

但是，我遇到此错误：

Traceback (most recent call last):
  File "/Users/Mady/Documents/EyePACSMLModelTest1.py", line 19, in <module>

这是我第一次使用该模型，该错误表示什么？

谢谢！

例外：使用InceptionV3时，URL提取失败...
