[GitHub] [tvm] Ubospica opened a new pull request, #14591: [MetaSchedule] Handle cases when no features found by FeatureExtractor

Ubospica opened a new pull request, #14591:
URL: https://github.com/apache/tvm/pull/14591

   Problem: `topi.full` module cannot be correctly tuned.
   
   Background: MetaSchedule system adopts a XGBoost model to predict the running performance of an IRModule based on features extracted from it. 
   
   Reason: Some operators like `topi.full` has so simple IRModule that no feature can be extracted. `topi.full` contains only one BufferStore node with a FloatImm value, so `PerStoreFeature` extractor cannot find any feature from it. And the XGBModel also cannot handle cases when there is no features.
   
   This PR specifically handles this case in `PerStoreFeatureNode` and `XGBModel`.
