I am trying to train models with "Time ordering" enabled on the attached dataset I get the error message below, but training sails successfully when "Time ordering" is not enabled. The file is a merger of the "train", "store" and "features" files from https://www.kaggle.com/c/walmart-recruiting-store-sales-forecasting/data.
What I am doing wrong? I changed meanings variables to no avail.
Read the logs
Failed to train : <class 'dataiku.doctor.preprocessing.dataframe_preprocessing.DkuDroppedMultiframeException'> : ['target'] values all empty or with unknown classes (you may need to recompute the training set)
The log is included in the attached text file.
I'm trying to reproduce your issue with the data you provided but managed to successfully train a model with time-ordering split. Could you try the following ?
If this doesn't solve your issue could you please provide us additional information ?
Thanks in advance for your feedback and have a good day,
I've tried to reproduce your issue with the data you provided and the settings I could see in the logs but unfortunately without success. We might need to investigate a bit more to understand where this issue comes from. Could you please contact our technical support by email at support -at- dataiku -dot- com ? Our support team will guide you but you can start by providing them the logs and data sample you sent me.
Sorry for not being able to find your issue and good luck.
