Hi!
With the new changes In Machine Learning.Net with the 0.7.0 version, the ability to peek in the data while is processed in each step of the pipeline is a little more complicated. A while ago, explain how we could do this in the post [Understanding the step bystep of Hello World]. However, ML.Net now uses Lazy objects, so it is not possible to debug in this step-by-step mode.
One of the options that we have available, is detailed in the ML.Net Cookbook, in the section [How do I look at the intermediate data?] and a complete explanation can be read in [Schema comprehension in ML.NET]
Well, the machine Learning.Net team has created a series of operations that can help us with these scenarios in the class [https://github.com/dotnet/machinelearning-samples/blob/master/samples/csharp/common/ConsoleHelper.cs]. In the following example, based on the examples of my Machine Learning.Net sessions, I use these functions to display the first 4 rows of the initial data set and also to display the values created for the Features column
So far, it works 😀
Happy Coding.
Greetings @ Microsoft IoT
