Can't load save_path when it is None.

[annaakhil]

I am training the model and it is taking longer than expected so I killed the process.
However, when I am running inference.py, I am getting an error
Traceback (most recent call last):
File "inference.py", line 92, in
saver.restore(sess, tf.train.latest_checkpoint(model_dir))
File "C:\Users\AKHIL\Anaconda3\lib\site-packages\tensorflow_core\python\training\saver.py", line 1277, in restore
raise ValueError("Can't load save_path when it is None.")
ValueError: Can't load save_path when it is None.
can anyone please look into it?
