Error using Azue ML Excel Add-In to connect to Machine Learing Web Service. RRS feed

  • Question

  • I have been using the Azure ML Excel Add-In available from the following site. 

    http://azuremlexcel.codeplex.com/

    I am getting the following error.

    "Failed to connect  to prediction REST API endpoint: The remote server returned an error: (400)   Bad Request.. Please check the URL."

    When I test my web service on Azure it works.  This error seems intermittent when using the Add-In.  Is there something I can look at on the Azure side?

  • Can you please provide API help page URL? I suspect your column names have a special characters or spaces or 0s. Also, please make sure you have latest plugin version from here - http://azuremlexcel.codeplex.com/ as API schema has changed post GA launch.

  • Is your dataset really large? If it is a rather small dataset you are trying to score, you could try to download the auto-generated Excel file from the web-service page and use it to score your data (by default it has only 1 row but you can use it to score multiple rows).
