Got No such file or directory error while serving the endpoint

[masab019]

Hello Everyone!

I'm using Databricks for my MLOps learning, and I'm following the tutorial, and I got an error while serving the endpoint. I need help in this.

Problem Overview:

I have created a basic LightGBM model and logged it in the Unity Catalog. Then, I created a custom PyFunc wrapper for the model. Now, I need to serve an endpoint for my PyFunc wrapper model, which in this case is my custom model.

Unfortunately, I’m encountering the following error:

OSError: No such file or directory: '/model/artifacts'

I need help resolving this issue. I have double-checked everything, including the artifacts, and everything seems normal to me.

Hello!

The error OSError: No such file or directory: '/model/artifacts' usually means your PyFunc model is missing required files during deployment. Make sure you’ve logged the model correctly with all necessary artifacts, and that your custom wrapper references them properly. If using Unity Catalog, verify the model URI and version are accurate. You may need to re-log the model with explicit artifact paths using mlflow.pyfunc.log_model() to ensure everything is included.
