LOAD ERROR

[Queenyy]

Thanks for your implementation!!
When I load the saved model, it has always been wrong. It always says:Unknown initializer: W_init.....
Could you please help me to solve it? Thanks very much!

It looks like you're trying to load a saved model in another script, but it's not finding W_init, (the custom initializer defined in the jupyter notebook). There are two solutions I would try first:

1. copy and paste the definition of W_init and b_init into your script
2. If that doesn't work, modify the jupyter notebook to use built in keras initializers instead of W_init and b_init and train again.

Please tell me if this works for you!
