[BUG] using NextItNet in main/examples/00_quick_start/sequential_recsys_amazondataset.ipynb

[OhitsaSteve]

Hi :)

Description

We want to use the NextItNet Recommender. For that we are using the quickstart example, friendly provided by you.
(main/examples/00_quick_start/sequential_recsys_amazondataset.ipynb)
Additionally we have modify some lines in the ipynb like by your comments described.
Unfortunately it asserts by line "model = SeqModel(hparams, input_creator, seed=RANDOM_SEED)" at part "2. Create model" with

ValueError                                Traceback (most recent call last)
Cell In[34], line 1
----> 1 model = SeqModel(hparams, input_creator, seed=RANDOM_SEED)
      3 ## sometimes we don't want to train a model from scratch
      4 ## then we can load a pre-trained model like this: 
      5 #model.load_model(r'your_model_path')

ValueError: The initializer passed is not valid. It should be a callable with no arguments and the shape should not be provided or an instance of `tf.keras.initializers.*' and `shape` should be fully defined. 

How do we replicate the issue?

take original "main/examples/00_quick_start/sequential_recsys_amazondataset.ipynb" and use NextItNet as through your comments described.

Expected behavior (i.e. solution)

run NextItNet successful with amazondata set.
We was apply to run all codeblocks with the other GRU [2], Caser [3], A2SVD [1], SLi_Rec [1], and SUM [5] recommender.

[miguelgfierro]

This might be related to the issues we've been having with the newest Keras. @SimonYansenZhao do you think this could be related to the issues with TF?

@OhitsaSteve can you check that you have TF < 2.16 #2071

[OhitsaSteve]

Thanks for your support :)

Yes, we are using TF < 2.16 . its currently 2.15.0

Btw in the upper code block its still the "sli_req.yaml" , we tried it with the modified "nextitnet" , sorry
