I solely had 1 SparkPool which was provisioned utilizing Apache Spark model 3.1. So after I created my Regression Azure Machine Studying mannequin it defaulted to that Spark Pool. After I clicked on the Create run button, after some moments, I obtained the next error…
Determine 1, Couldn’t discover Linked Service, the linked service doesn’t exist or will not be revealed
I didn’t discover any info or documentation about this, so I made a decision to take one other strategy. As an alternative of urgent the Create run button I click on the Open in pocket book button.
Determine 2, Couldn’t discover Linked Service, the linked service doesn’t exist or will not be revealed
After I ran the primary cell I obtained this error and thought I had discovered the issue, I used to be so joyful. So I created a second Spark pool that focused model 2.4 as instructed.
****** AutoML Conditions ******
AutoML requires an Apache Spark pool (model 2.4) in your Azure Synapse Analytics workspace.
You’re utilizing a Spark 3.x pool, please use Spark 2.x pool.
Determine 3, Couldn’t discover Linked Service, the linked service doesn’t exist or will not be revealed
Then, this second error went away…I walked via the remaining cells, one after the other, the following one failed. It failed at this line of code with the identical error as earlier than. (Entry token couldn’t be obtained,LSRServiceException, Couldn’t discover Linked Service, the linked service doesn’t exist or will not be revealed)
ws = mssparkutils.azureML.getWorkspace(linkedService_name)
It seems that it’s worthwhile to Publish your Linked service. There could also be extra required steps, however the resolution is to push the Publish button.
Determine 4, Couldn’t discover Linked Service, the linked service doesn’t exist or will not be revealed
