C2_Week 3 Assignment: Data Pipeline Components for Production ML

As the notebook stacktrace shows, you’ve not used instance of tfx.types.standard_artifacts.Schema but an instance of tfx.types.standard_component_specs.ImportSchemaGenSpec.
The variable user_schema_importer has the schema inside it (see the previous cell where you access it).

Cover_Type will display as an INT field. Hope this reply helps.
