AttributeError：模塊'tensorflow.contrib.slim'沒有屬性'nets'

Question

我想使用內置resnet的tf-slim進行快速實驗。我根據README在github那樣：

import tensorflow as tf 
import tensorflow.contrib.slim as slim 

resnet = tf.contrib.slim.nets.resnet_v1 

mnist = input_data.read_data_sets('MNIST_data', one_hot=True) 
x = tf.placeholder("float", shape=[None, 784]) 
y_ = tf.placeholder("float", shape=[None, 10]) 
pred = resnet.resnet_v1_50(x) 

cross_entropy = -tf.reduce_sum(y_ * tf.log(pred)) 

，但得到這樣的錯誤：AttributeError: module 'tensorflow.contrib.slim' has no attribute 'nets'。我已經安裝了最新版本的tensorflow-0.12.0。
我該如何解決這個問題？

Answer 1

進口這樣的：

from tensorflow.contrib.slim.nets import resnet_v1 

slim = tf.contrib.slim
