Poor picklability of keras is a long-known issue (you can google keras with the same mistake error).
You may be fortunate to have some of variables being passed e.g. in lambda not through calls,

But otherwise I'm not sure there will be a simple solution

Yes, but of course keras has its own save_model functionality. So do you think it is simply not possible to save a uBoost model which is based on a keras model?

It all goes down do pickle-ability of items.
hep_ml's uBoost is completely pickle-able, but keras model is not.
Option 1. Ask keras maintainers why your model is not pickle-able
Option 2. Store keras models separately from uBoost.
estimators = clf.estimators_ # list of keras models
# TODO save estimators somehow using keras tools
# delete estimators
clf.estimators_ = None
with open('uboost.pkl', 'wb') as f:
joblib.dump(clf, f)
# loading
with open('uboost.pkl', 'rb') as f:
clf = joblib.load(f)
estimators = .... # load estimators
clf.estimators_ = estimators

there is option 3 as well - find truly sklearn-compatible NN package =)

Ok I will try to implement option 2, thanks!
