InvalidArgumentError

[Chuan1997]

Hello, I came across an error, when running the code:
_Traceback (most recent call last):

File "E:\Anaconda\envs\py36\lib\site-packages\tensorflow\python\client\session.py", line 1356, in _do_call
return fn(*args)

run_metadata)

InvalidArgumentError: indices[252,12] = 1073 is not in [0, 944)
[[{{node embedding_lookup_2}}]]

During handling of the above exception, another exception occurred:

Errors may have originated from an input operation.
Input Source operations connected to node embedding_lookup_2:
Placeholder_2 (defined at D:\Study\reproduction\LGRec\code\LGRec.py:178)
user_embedding/read (defined at D:\Study\reproduction\LGRec\code\LGRec.py:183)_

Could you please provide some advices on solving the problem?
