MLFlow Error

[adithyasanker]

On running https://www.databricks.com/notebooks/mlops/deploy_azure_ml_model_.html

At the build docker image step, 

mlflow.azureml.build_image

I faced an error ''TypeError: join() argument must be str, bytes, or os.PathLike object, not 'dict''' .

The model is now registered successfully in azureml but the docker image creation fails. I'm using the Spark 12.2 LTS ML Compute.

Could this be an mlflow version issue?
