unable to execute completely

[srinathdwivedi]

i am trying to run modelv1.
now at following stage new error is occurring:
model = tf.train.latest_checkpoint(model_dir)
saver.restore(sess, model)
error:
INFO:tensorflow:Restoring parameters from None

---

TypeError Traceback (most recent call last)
TypeError: expected bytes, NoneType found

The above exception was the direct cause of the following exception:

SystemError Traceback (most recent call last)

SystemError: returned a result with an error set

i would like to know why it is occurring is there any sequence to run different models?

[ProxyCausal]

got a different error:
Can't load save_path when it is None.
although i think thats because its the first time training and there is no saved model yet
since training involves saver.save(sess, model_dir + '/model')

so i skipped running that cell and ran all below, and got another error:
InvalidArgumentError: Inputs to operation gradients_1/AddN_973 of type AddN must have the same size and shape.

[Sshanu]

are you using python3?

[ProxyCausal]

Yes

someone was also facing the same issue, you can ask them

[zy158]

@ProxyCasual Hi, have you solved the problem you meet? Input 0: [2,7,1,100] != input 1: [2,1,1,100]. How did you solve it?

[damao666]

Have you solved this problem? I have the same problem.

Traceback (most recent call last):

word_embedding_saver.restore(sess, latest_embd)

Facing the same problem :

ValueError Traceback (most recent call last)
in ()
1 model = tf.train.latest_checkpoint(model_dir)
----> 2 saver.restore(sess, model)

F:\anaconda\lib\site-packages\tensorflow\python\training\saver.py in restore(self, sess, save_path)
1272 return
1273 if save_path is None:

1275
1276 if not checkpoint_management.checkpoint_exists(compat.as_text(save_path)):

ValueError: Can't load save_path when it is None.

Please help I am new learner.
