@Gonzalez Barba, Jorge Thanks for the question. Can you please share the sample input data. Azure AutoML currently supports data assets in the form of CSV and JSON files. It does not currently support image files stored in a data asset in the form of a folder URI. To use image files in an AutoML job, they should be stored in a supported format and location, such as in a CSV file with a link to the image file or in an Azure Blob storage container.
You can either convert your images to CSV or JSON file or use the Azure Blob storage container as the input for your AutoML job.
