saver = tf.train.import_meta_graph('./fcn_8s_checkpoint/model_fcn8s_final.ckpt.meta') saver.restore(sess,"./fcn_8s_checkpoint/model_fcn8s_final.ckpt")

Got an error on TF 1.3.0 without GPU, any idea?

@caxton how did you solve it? I have got a similar issue.

[Senyao-Han]

I got this issue too. Do you solve this problem and how?
