这里是TensorFlow的一个新bug

把

saver.restore(sess,"./mnist/data/convolutional.ckpt")

改成

module_file =  tf.train.latest_checkpoint('mnist/data/convolutional.ckpt')
with tf.Session() as sess:
   sess.run(tf.global_variables_initializer())
   if module_file is not None:
      saver.restore(sess, module_file)

就可以了
