RuntimeError: Load model failed - Score machine learning models with PREDICT in serverless Apache Spark pools (Synapse & Azure Machine learning AML)

Question

Hi all,

I am following the steps on this tutorial:
Tutorial: Score machine learning models with PREDICT in serverless Apache Spark pools tutorial-score-model-predict-spark-pool
I tried to used a model created with AutoML and another from designer and I am getting this error: RuntimeError: Load model failed

I am using the model according to this: https://learn.microsoft.com/en-us/answers/questions/631200/what-is-aml-model-uri-predict-in-serverless-apache.html?childToView=637754#comment-637754

Thank you for your help.

Hello @Anonymous ,

Before running this script, update it with the URI for ADLS Gen2 data file along with model output return data type and ADLS/AML URI for the model file.

#Set model URI  
       #Set AML URI, if trained model is registered in AML  
          AML_MODEL_URI = "<aml model uri>" #In URI ":x" signifies model version in AML. You can   choose which model version you want to run. If ":x" is not provided then by default   latest version will be picked.  
  
       #Set ADLS URI, if trained model is uploaded in ADLS  
          ADLS_MODEL_URI = "abfss://<filesystemname>@<account name>.dfs.core.windows.net/<model   mlflow folder path>"  

Model URI from AML Workspace:

DATA_FILE = "abfss://******@cheprasynapse.dfs.core.windows.net/AML/LengthOfStay_cooked_small.csv"  
AML_MODEL_URI_SKLEARN = "aml://mlflow_sklearn:1" #Here ":1" signifies model version in AML. We can choose which version we want to run. If ":1" is not provided then by default latest version will be picked  
RETURN_TYPES = "INT"  
RUNTIME = "mlflow"  

Model URI uploaded to ADLS Gen2:

DATA_FILE = "abfss://******@cheprasynapse.dfs.core.windows.net/AML/LengthOfStay_cooked_small.csv"  
AML_MODEL_URI_SKLEARN = "abfss://******@cheprasynapse.dfs.core.windows.net/linear_regression/linear_regression" #Here ":1" signifies model version in AML. We can choose which version we want to run. If ":1" is not provided then by default latest version will be picked  
RETURN_TYPES = "INT"  
RUNTIME = "mlflow"  

Hope this will help. Please let us know if any further queries.
