Hi

I am I am trying to follow the tutorial at this link here https://microsoftlearning.github.io/AI-900-AIFundamentals/instructions/02a-create-regression-model.html#create-training-pipeline

After performing the steps listed under create and run an interface pipeline

User's image

I get 2 failed nodes/select_columns_in_dataset, /execute_python_script as seen below.

User's image

Steps 7 mentions "Now that you’ve changed the schema of the incoming data to exclude the price field, you need to remove any explicit uses of this field in the remaining modules. Select the Select Columns in Dataset module and then in the settings pane, edit the columns to remove the price field." However, I tried to do this and I get the same errors

  1. Select_column_in_Dataset:ModuleExceptionMessage:ColumnNotFound: Column with name or index "price" not found.
  2. Execute_python_script:ModuleExceptionMessage:InvalidDataset: Dataset1 is not valid, reason: input path does not exist. There are several possible causes: 1. Your input is a registered dataset but the dataset is invalid; 2. Your input is the output of a reused module, but the output of the module is removed;

Please help. I tried changing this in multiple different ways but nothing has worked for me.

    Thank you for your response and sorry for the delay in getting back to your response. I think there must've been a glitch in the system. I restarted my computer and it all worked out fine after that.
