tutorial_translate.py raise Exception("no %s exist" % ckpt.model_checkpoint_path)

[terryKing1992]

Hi Guys, I have trained the translation model using python tuaorial_translate.py, then i want using my own words to test the model,so i switch the main_train() to main_decode(), but the python shell raise one exception; more information as follow:
first, the exception occurs at 391 lines of tutorial_translate.py if ckpt and tf.gfile.Exists(ckpt.model_checkpoint_path)；and the ckpt object is not null, ckpt.model_checkpoint_path value is 'wmt/model_translate_enfr.ckpt-10'; in fact, the directory does not have this file , i wonder why the pre-sentence ckpt = tf.train.get_checkpoint_state(train_dir) return the error data, hope your help, please! thanks a lot

It seem that you have problem with ckpt.
Did you set a correcttrain_dir?
Alternatively, can you set is_npz = True then it will save the model into npz file instead of ckpt, it may help.

yeah, my train_dir is a relative file path wmt, isn't it true? i'll try to set is_npz=True, should i remove the generated data and train the translate model again?
