【问题描述】:
我想使用从一组图像中提取的 pool_3 特征。目前我对每个图像都有一个循环来提取 pool_3 特征:
# X_input.shape = (40000, 32, 32, 3)
def batch_pool3_features(X_input):
sess = tf.InteractiveSession()
n_train = X_input.shape[0]
print 'Extracting features for %i rows' % n_train
pool3 = sess.graph.get_tensor_by_name('pool_3:0')
X_pool3 = []
for i in range(n_train):
print 'Iteration %i' % i
pool3_features = sess.run(pool3,{'DecodeJpeg:0': X_input[i,:]})
X_pool3.append(np.squeeze(pool3_features))
return np.array(X_pool3)
虽然这很慢。是否有更快的批处理实现来执行此操作?
谢谢
