Issues Starting ML Services

R

Jen Stirrup has a quick rundown of some reasons why Machine Learning Services might give you an error when you try to start it up:

Msg 39023, Level 16, State 1, Procedure sp_execute_external_script, Line 1 [Batch Start Line 3]

‘sp_execute_external_script’ is disabled on this instance of SQL Server. Use sp_configure ‘external scripts enabled’ to enable it.

Msg 11536, Level 16, State 1, Line 4

EXECUTE statement failed because its WITH RESULT SETS clause specified 1 result set(s), but the statement only sent 0 result set(s) at run time.

Grr! What’s happened here? We had installed R as part of the SQL installation, and we had run the command to enable it, too.

Click through for reasons.  One thing which might affect a small percentage of people is that ML Services creates a folder each time you run an R query.  Those folders are easy to clean up, and each time the Launchpad service starts up, it deletes the old folders as a step.  The problem is that if you have a huge number (tens or hundreds of thousands), it might not get finished deleting in time and the service will fail.  Deleting the folders manually does the trick and the service can start up once more.
