Detailed Description
A data iterator for XGBoost DMatrix. `reset` and `next` are required for any data iterator, other functions here are utilites for demonstration's purpose.
Constructor & Destructor Documentation
◆ __init__()
| quantile_data_iterator.IterForDMatrixDemo.__init__ | ( | self | ) |
Generate some random data for demostration. Actual data can be anything that is currently supported by XGBoost.
Reimplemented from xgboost.core.DataIter.
Member Function Documentation
◆ data()
| quantile_data_iterator.IterForDMatrixDemo.data | ( | self | ) |
Utility function for obtaining current batch of data.
◆ labels()
| quantile_data_iterator.IterForDMatrixDemo.labels | ( | self | ) |
Utility function for obtaining current batch of label.
◆ next()
| quantile_data_iterator.IterForDMatrixDemo.next | ( | self, | |
| input_data | |||
| ) |
Yield next batch of data.
Reimplemented from xgboost.core.DataIter.
◆ reset()
| quantile_data_iterator.IterForDMatrixDemo.reset | ( | self | ) |
Reset the iterator
