error loading databricks.proto

Hi,

I'm using a DBR 13.3 LTS ML, and I want to set up a webhook trigger. I'm following the example notebook at https://learn.microsoft.com/en-us/azure/databricks/_extras/notebooks/source/mlflow/mlflow-model-registry-webhooks-python-client-example.html.

This is the code I'm using:

%pip install databricks-registry-webhooks
dbutils.library.restartPython() # not needed for DBR < 13.3
from databricks_registry_webhooks import RegistryWebhooksClient, JobSpec, HttpUrlSp

The last line throws the following error:

TypeError: Couldn't build proto file into descriptor pool! Invalid proto descriptor for file "databricks.proto": databricks.proto: A file with this name is already in the pool.

Finally, I successfully tested the same issue on DBR 10.4 ML, 11.3 ML and 12.2 ML with no errors

Hi @FranPérez ,

The issue is that databricks-registry-webhooks has a databricks.proto file that collides with mlflow. Here is the fix:

%pip install databricks-registry-webhooks mlflow==2.2.2

I also posted the fix on StackOverflow: https://stackoverflow.com/a/78097127/1290485
