Keras提供了一些用ImageNet训练过的模型：Xception，VGG16，VGG19，ResNet50，InceptionV3。在使用这些模型的时候，有一个参数include_top表示是否包含模型顶部的全连接层，如果包含，则可以将图像分为ImageNet中的1000类，如果不包含，则可以利用这些参数来做一些定制的事情。
在运行时自动下载有可能会失败，需要去网站中手动下载，放在“~/.keras/models/”中，使用WinPython则在“settings/.keras/models/”中。
修正：表示当前是训练模式还是测试模式的参数K.learning_phase()文中表述和使用有误，在该函数说明中可以看到：
The learning phase flag is a bool tensor (0 = test, 1 = train)，所以0是测试模式，1是训练模式，部分网络结构下两者有差别。
这里使用ResNet50预训练模型，对Caltech101数据集进行图像分类。只有CPU，运行较慢，但是在训练集固定的情况下，较慢的过程只需要运行一次。
该预训练模型的中文文档介绍在http://keras-cn.readthedocs.io/en/latest/other/application/#resnet50。

从文件夹中提取图像数据的方式：

调用：
global Width, Height, pic_dir_out, pic_dir_data
Width = 224

num_classes = 102 #Caltech101为102 cifar10为10

载入预训练模型ResNet50，并将训练图像经过网络运算得到数据，不包含顶部的全连接层，得到的结果存成文件，以后可以直接调用（由于我内存不够，所以拆分了一下）：
input_tensor = Input(shape=(224, 224, 3))
base_model = ResNet50(input_tensor=input_tensor,include_top=False,weights='imagenet')
#base_model = ResNet50(input_tensor=input_tensor,include_top=False,weights=None)
get_resnet50_output = K.function([base_model.layers[0].input, K.learning_phase()],
[base_model.layers[-1].output])
file_name = os.path.join(pic_dir_mine,'resnet50_train_output'+'.h5')
if os.path.exists(file_name):
f = h5py.File(file_name,'r')
resnet50_train_output = f['resnet50_train_output'][:]
f.close()
else:
resnet50_train_output = []
delta = 10
for i in range(0,len(X_train),delta):
print i
one_resnet50_train_output = get_resnet50_output([X_train[i:i+delta], 0])[0]
resnet50_train_output.append(one_resnet50_train_output)
resnet50_train_output = np.concatenate(resnet50_train_output,axis=0)
f = h5py.File(file_name,'w')
f.create_dataset('resnet50_train_output', data = resnet50_train_output)
f.close()
将ResNet50网络产生的结果用于图像分类：
input_tensor = Input(shape=(1, 1, 2048)) x = Flatten()(input_tensor) x = Dense(1024, activation='relu')(x) predictions = Dense(num_classes, activation='softmax')(x) model = Model(inputs=input_tensor, outputs=predictions) model.compile(optimizer=Adam(), loss='categorical_crossentropy',metrics=['accuracy'])
训练图像数据集：
print('\nTraining ------------') #从文件中提取参数，训练后存在新的文件中
cm = 0 #修改这个参数可以多次训练
cm_str = '' if cm==0 else str(cm)
cm2_str = '' if (cm+1)==0 else str(cm+1)
if cm >= 1:
model.load_weights(os.path.join(pic_dir_mine,'cnn_model_Caltech101_resnet50_'+cm_str+'.h5'))
model.fit(resnet50_train_output, y_train, epochs=10, batch_size=128,)
model.save_weights(os.path.join(pic_dir_mine,'cnn_model_Caltech101_resnet50_'+cm2_str+'.h5'))
测试图像数据集：

y_test = np_utils.to_categorical(y_test, num_classes)

if os.path.exists(file_name):
f = h5py.File(file_name,'r')
resnet50_test_output = f['resnet50_test_output'][:]
f.close()
else:

delta = 10
for i in range(0,len(X_test),delta):
print i
one_resnet50_test_output = get_resnet50_output([X_test[i:i+delta], 0])[0]
resnet50_test_output.append(one_resnet50_test_output)
resnet50_test_output = np.concatenate(resnet50_test_output,axis=0)
f = h5py.File(file_name,'w')
f.create_dataset('resnet50_test_output', data = resnet50_test_output)
f.close()
print('\nTesting ------------') #对测试集进行评估
class_name_list = get_name_list(pic_dir_data) #获取top-N的每类的准确率
pred = model.predict(resnet50_test_output, batch_size=32)
输出测试集各类别top-5的准确率：

pred_list = []
for row in pred:
pred_list.append(row.argsort()[-N:][::-1]) #获取最大的N个值的下标
pred_array = np.array(pred_list)

if test_arg[i] in pred_array[i]:

print('top-'+str(N)+' all acc:',str(sum(class_acc))+'/'+str(len(test_arg)),sum(class_acc)/float(len(test_arg)))

《魔兽世界》大逃杀！60人新游玩模式《强袭风暴》3月21日上线
暴雪近日发布了《魔兽世界》10.2.6 更新内容，新游玩模式《强袭风暴》即将于3月21 日在亚服上线，届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。
艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕，并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时，他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中，玩家将会进入一个全新的海盗主题大逃杀式限时活动，其中包含极高的风险和史诗级的奖励。
《强袭风暴》不是普通的战场，作为一个独立于主游戏之外的活动，玩家可以用大逃杀的风格来体验《魔兽世界》，不分职业、不分装备（除了你在赛局中捡到的），光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式，玩家在加入海盗主题的预赛大厅区域前，可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹，《巨龙崛起》和《魔兽世界：巫妖王之怒 经典版》的玩家都可以获得奖励。
