I got error in inference pipeline in Azure machine Learning notebook

Question

ı am learning machine learning on microsoft learn and ı have problem with inference pipeline
inference-pipeline

Answer 1

@Tunahan DENİZ Thanks for the question. Can you please add more details steps that you performed. If you have changed the schema of the incoming data to exclude the price field, you must remove any explicit use of this field in other modules.

Please follow the document to create a real-time inference pipeline.

We are able to create inference pipeline without any errors as shown below.

Answer 2

you can try keeping "price" column in the dataset in the first Box,
Enter Data manually: price,column2,col3,....col10
Select Columns in Dataset: price,column2,col3,....col9 (choose which columns to import, omit col10 for example) Though the learning path says to remove price column, try keeping it in.
And you may be interested in Edit Metadata asset box. It allows your model to import the columns and associate the features with the predicted price. So instead of just seeing a predicted price, you can output, what you fed the model. Overall, did you get it to work by starting over? That learning Path worked for me when I followed all steps. maybe these extra ideas will help.

Answer 3

Same issue for me. The workaround to add a fake "price" column to the manual raw data was the easiest solution to get the pipeline to work.

The "Apply Transformation" step is expecting the price so removing the price in the "select step" doesn't work.
