Oracle Pickles are outdated

[amva13]

          Got it. Thanks for pointing out. The best solution is to pickle these solutions with a more modern scikit (or invoke the models with a different method entirely to avoid the dependency issues altogether). For now the downgrade seems to work, though that particular classifier came from version 0.23.0.. so not great. I'll flag this is a longer term issue to look at.
