Hey there, so I am having trouble training new models on an existing project, if I either update an existing recipe or deploy the newly trained model in a new visual tool in the flow whenever I try to score a dataset,
I am getting the following error:
Error in python process: <class 'dataiku.base.dku_pickle.PickleLoadException'>: Failed to load model from file /home/dataiku/cache/saved_models/EXPIRED_COUPONS/KsqBonL3/versions/initial/clf.pkl
Does anyone know what this could be or how to fix it? (EXPIRED_COUPONS is the project name)
