One thing I think it's useful to point out for Databricks users is that you would typically not use MLflow Projects to describe execution of a modeling run. You would just use MLflow directly in Databricks and use Databricks notebooks to manage code ...

You could monkey patch MLFlow's _get_dbutils() with something similar to this to get this working while connecting from dbconnectspark = SparkSession.builder.getOrCreate() # monkey-patch MLFlow's _get_dbutils() def _get_dbutils(): return DBUtils(...

There shouldn't be. Generally speaking, models will be serialized according to their 'native' format for well-known libraries like Tensorflow, xgboost, sklearn, etc. Custom model will be saved with pickle. The files exist on distributed storage as ar...
