NotFoundError: encountered while running function tf.train.latest_checkpoint() in predict.py

Both the model and the checkpoints exist in the same directory. This is the error i encounter when i try to run the file.

Thank you. Though i saved the model as a ckpt file and to call the model ran these commands

saver = tf.train.import_meta_graph(checkpoint_dir + 'checkpoints/generator.ckpt.meta')  
saver.restore(sess, tf.train.latest_checkpoint(checkpoint_dir + 'checkpoints'))   

The prediction script worked for me then.
You can now close the issue if you like, it's resolved from my side.
