基于tensorflow加载部分层的方法

saver.restore(sess, modeldir + "model.ckpt")

var_list = [weights['wd1'], weights['out'], biases['bd1'], biases['out'], global_step]
initfc = tf.variables_initializer(var_list, name='init')

sess.run(init)
saver.restore(sess, modeldir + "model.ckpt")
print sess.run(global_step)
#initialize several  
sess.run(initfc)
print sess.run(global_step)
