c++调用vgg16:

./build/install/bin/classification \
/media/whale/wsWin10/wsCaffe/model-zoo/VGG16//deploy.prototxt \
/media/whale/wsWin10/wsCaffe/model-zoo/VGG16/VGG_ILSVRC_16_layers.caffemodel \
data/ilsvrc12/imagenet_mean.binaryproto \
/media/whale/wsWin10/wsCaffe/model-zoo/VGG16/synset_words.txt \
/media/whale/wsWin10/images/person/2.jpg

然后就报错了。

然后

whale@sea:/media/whale/wsWin10/wsUbuntu16./DlFrames/caffe$ ./build/install/bin/classification /media/whale/wsWin10/wsCaffe/model-zoo/VGG16//deploy.prototxt /media/whale/wsWin10/wsCaffe/model-zoo/VGG16/VGG_ILSVRC_16_layers.caffemodel data/ilsvrc12/imagenet_mean.binaryproto ./3labels.txt /media/whale/wsWin10/images/person/2.jpg
labels_.size() = output_layer->channels() = ---------- Prediction for /media/whale/wsWin10/images/person/.jpg ----------

只能给3个标签，不然就报错。然后，。。。，这个模型是假的吗？

还是什么是假的？

keras-python调用vgg16:

python-keras接口调用模型要简单些，只需要标签文件，和keras模型就可以了。

from keras.applications.vgg16 import VGG16
from keras.preprocessing import image
from keras.applications.vgg16 import preprocess_input
from keras.models import Model
import numpy as np
import matplotlib.pyplot as plt

get_ipython().magic(u'matplotlib inline')

### 显示图像

In[2]:

img_path = './data/elephant.jpg'
img_path = '/media/whale/wsWin10/images/dog/0c02094a98d126cf541c4318188699a5.jpg'
img_path = '/media/whale/wsWin10/images/dog/dd92db98b99479db3619f62c724757a4.jpg'

img = image.load_img(img_path, target_size=(224, 224))

plt.imshow(img)
plt.show( )

### 加载VGG16模型（包含全连接层）

In[3]:

model = VGG16(include_top=True, weights='imagenet')
print(" type(model) = ", type(model))

In[4]:

x = image.img_to_array(img)

x = np.expand_dims(x, axis=0)

x = preprocess_input(x)

print( "x.max() = ", x.max())

scores = model.predict(x)

In[10]:

class_table = open('./data/synset_words', 'r')
lines = class_table.readlines()
print(" scores type: ", type(scores))
print(" scores shape: ", scores.shape)
print(" np.argmax(scores) = ", np.argmax(scores))
print('result is ', lines[np.argmax(scores)])
class_table.close()

import sys
sys.exit()
