问题
When I use data factory to update Azure ML models like the document said (https://docs.microsoft.com/en-us/azure/data-factory/v1/data-factory-azure-ml-update-resource-activity),
I faced one problem:
The blob reference: test/model.ilearner has an invalid or missing file extension. Supported file extensions for this output type are: ".csv, .tsv, .arff".'.
I have searched the problem and found this solution:
https://disqus.com/home/discussion/thewindowsazureproductsite/data_factory_create_predictive_pipelines_using_data_factory_and_machine_learning_microsoft_azure/ .
But my linked service for the outputs of training service pipeline and update service pipeline are already different.
How can I solve this problem?
