[DanielSe]

System Information (please complete the following information):

• mlnet cli version: 16.15.1+5cfa5322dc43fb36001cafd7c46e716141dfa219

Describe the bug

• When running an mlnet image-classification command an exception is encountered:

  System.NotImplementedException: The method or operation is not implemented.

To Reproduce Steps to reproduce the behavior:

1. Download ´assets.zip´ from https://github.com/dotnet/machinelearning-samples/tree/main/samples/modelbuilder/ImageClassification_Azure_LandUse
2. Extract archive: $ unzip assets.zip
3. Run: $ mlnet image-classification --dataset ./assets
4. See error

Expected behavior Expection is for the Cli tool to use AutoML to train a model on the dataset.

Got thet problem too. They had fixed it in a previous issue, but I guess it's back again.
