How to view data inside IDataView

Question

In ML.net, I want to view the data in the IDataView to verify whether the right data is loaded. I cannot see any visualizer/debugging tool to view them just like we view in System.Data.DataTable as a table

var mlContext = new MLContext();
IDataView trainData = mlContext.Data.LoadFromTextFile<TaxiTrip>(GetAbsolutePath("../../taxi-fare-test.csv"), hasHeader: true);

Answer 1

There's a Preview method for the IDataView. You can run that method in a variable and debug through there to look at the data.

var preview = trainData.Preview();
