TextCatalog.ApplyWordEmbedding to KMeans Trainer generates IndexOutOfRangeException#4397

System information

  • OS version/distro: Windows 10 PRO 10.0.18362
  • .NET Version (eg., dotnet --info): 3.1.100-preview1-014459

Issue

I am trying to cluster a group of documents. For this sample, I used news articles short descriptions. If I run this sample with FeaturizeText the sample builds a model. If I try to apply TextCatalog.ApplyWordEmbedding I get a System.IndexOutOfRangeException.

  • What did you do? Applying Wordembedding to KMeans Trainer
  • What happened? IndexOutOfRangeException
  • What did you expect? For the ML.NET to build my model

Source code / logs

Sample code to reproduce the problem can be found here.

                  Issue
                  I am trying to cluster a group of documents. For this sample, I used news articles short descriptions. If I run this sample with FeaturizeText the sample builds a model. If I try to apply TextCatalog.ApplyWordEmbedding I get a System.IndexOutOfRangeException.

                          I am trying to cluster a group of documents. For this sample, I used news articles short descriptions. If I run this sample with FeaturizeText the sample builds a model. If I try to apply TextCatalog.ApplyWordEmbedding I get a System.IndexOutOfRangeException.
