no_pca.keras error

[DaichiFujiwara]

Hello, I have a problem for no_pca.keras file.

I loaded this model and just wanted to do 'model.predict(latent_vector)".
But I always got an error, which says "Could not find variable dense_3/kernel".
Do you have an idea to resolve this problem?

Just to be sure, I show the hierarchical structure of loaded model.
My environment is Python 3.6, tensorflow 2.6.0, keras 2.6.0.

Thanks in advance.
