Unable to load saved model

[Masquerade0097]

I saved the model after training using the following commands

saver = tf.train.Saver()
saver.save(sess, '../data/output/'+folder_name+'/model/var_autoencoder_model')

Then in another test script, I restored the model using the following commands

saver = tf.train.import_meta_graph('../data/output/'+folder_name+'/model/var_autoencoder_model.meta')
saver.restore(sess, '../data/output/'+folder_name+'/model/var_autoencoder_model')

But the model is failing with the following error
