NotFoundError (see above for traceback): Key regression/Variable not found in checkpoint

解决方法

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
