```

**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.
