session 1.

k = 100
user_id = '1035369'
index = tfrs.layers.factorized_top_k.BruteForce(model.user_model,k)
index.index_from_dataset(

)
print(f"rec user_id :{user_id}")
print(user_id in unique_user_id)

is right。

session 2:

• _model = build_model() #delete
• model.fit(behavior_dataset, epochs=30) #delete
• model.save_weights(save_path,overwrite=True )#delete_

print(user_id in unique_user_id)

is wrong 不准确。

tensorboard 2.15.2
keras 2.15.0

colab can is right ,but same version pip list my pc is wrong
