Training successfully completed for pipeline type:TRAIN ONLY/FULL/EVALUATION but within the pipeline report it shows as "results.json blob is missing or invalid".
Issue Description: Yet times, the train pipeline or others (FULL/EVALUATION) will be successful but it fails to run.
Root Cause: Failed to create the results.json.
Resolution:
- Go to the pipeline and download the zip file. (in my case) “invoice_extractor.zip“ should be there. Save this for step 4.
- Navigate to the package you have used for training. Choose the version used for training and download the artifacts. You only need the “…metadata.json“ file.
- Edit metadata json, find the “trainingVersion” field and increase the number by 1. (ex change from 2 to 3). Save the file under a different name.
- In ML packages view, navigate to "Import ML Package". Use the zip file from the pipeline and the edited metadata file to upload a new package.
- Upload it in "Import ML Package" as shown below:
- A new version should be shown under the original package.
