Diagnosing a Missing Date Field in Rolling Model Training

Summary

This brief Chinese-language support thread concerns a rolling-training error reported as “NaTType does not support.” A response attributes the failure to a module whose output lacks a date column, and says the rolling-training process needs that field. The reply points the user to a simplified example strategy for reference. The discussion is about data structure and workflow troubleshooting, not a trading signal or quantitative method.

The thread contains no code, detailed reproduction steps, or confirmation that adding the date field resolved the original error. It does not establish whether the same cause applies to other projects or configurations. Its useful takeaway is limited: when rolling training encounters this date-related error, check whether the relevant module's data includes a properly populated date column. The suggested example may help, but the thread gives too little information to assess its implementation or generalize the diagnosis.

Key ideas

• The reported rolling-training failure is associated with a missing date column in one module's data.
• The suggested troubleshooting step is to verify that the relevant data includes a date field.
• A simplified example strategy is offered as a reference.
• The thread provides no confirmed fix, code details, or evidence that the diagnosis generalizes.
