InvalidArgumentError

[mujinmujin]

你号，运行代码时，我出现了如下错误：
_Traceback (most recent call last):

File "E:\Anaconda\envs\py36\lib\site-packages\tensorflow\python\client\session.py", line 1356, in _do_call

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)

请问你知道如何解决吗？
