Other Comments

FYI @SimonYansenZhao this is similar to the issue we got in #2022

• $ pytest tests/unit/recommenders/models/test_deeprec_model.py::test_lightgcn_component_definition working with TF 2.8.4 and CUDA 11.6
• $ pytest tests/smoke/recommenders/recommender/test_deeprec_model.py::test_model_lightgcn --disable-warnings working with TF 2.8.4 and CUDA 11.6

Still the same error in nightly GPU: https://github.com/recommenders-team/recommenders/actions/runs/8372395934/job/22923293913
