Not able to run the optimizer more than 10 times for Keras implementation

[eagq]

Hi!

I don't know if I should post this here but I encountered some difficulties trying to run your code on a Keras example more than 10 times at the 11th time I get an error like this:

TypeError: get_params() missing 1 required positional argument: 'self'

I don't why I get this if the code was able to run 10 times previously! I hope you can help.

Thanks in advance :)

@eagq Can I see the full traceback of the error you're experiencing?

@evhub Sure, here it is:

After a long hiatus of not working on this project, I've resumed work and have just fixed this issue.
