Fabric Python Notebook Execution Logs

nerminyehia — Mon, 20 Oct 2025 08:29:19 GMT

Hey,

I created a Python notebook to install and run dbt code, but when I call it from the pipeline, I can not get the execution logs

and get stuck in the loading state.

Thanks

Hi @nerminyehia,

The pipeline seems to be stuck because inline %pip install is disabled by default during notebook runs. As a result, installing dbt blocks execution and prevents logs from being streamed. Pre-install dbt in a Fabric Environment and attach it to your notebook or pipeline. This will allow for smooth execution and visible logs.

Thank you.

Hey,

Thank you so much for the suggestion. But I don't think it is related to the notebook content, because I tried to run an empty notebook with one print statement, but it keeps getting the same issue. I need to see the notebook run details whenever it is triggered by the pipeline.

Hi @nerminyehia,

The notebook might seem stuck because every notebook run through a pipeline needs a Spark session to start, even if it’s empty. To check what’s happening and see the logs, you can go to Run → All Runs and use the Related Notebook tab in the monitoring view. Turning on High Concurrency mode for pipelines helps notebooks share sessions more efficiently and makes sure the logs are visible while they run.

Thanks for your help. It works after allowing the high concurrency feature.
