Model execution and deployment on server

@mschmitz
Can you share the document where extensions are present or deployment process for them. I looked but couldn't find.  
I am just deploying a simple deep Learning model prepared on the titanic sample set available. Once deployed running the webservice gives me unknown operator error.

Simple process operator is itself showing me the error

@mschmitz I am attaching two images above, These are the recent tries I did post installation of rapid server.
* The first is post deploying the model into the server and executing the webservice request. The model building was done on studio. Check the response for unknown operator
* The second image I am trying to execute the auto model on the server itself just to be sure that the operators used are present in the server but I get this error.
I am trying to create a webservice url to for a sample set. 

@mschmitz this was resolved with the help of rapid team, there was some license issue for the server thanks
