I'm doing parameter tuning for a NeuralProphet model (you can see in the image the parameters and code for training)

When I try to parallelize the training, it gives me Permission Error.

Why can't I access the folder '/databricks/spark/work/*'? Do I need some aditional permissions to write on the cluster?

I also leave the error traceback. Thank you

Hello. Thank you for your answer. I have 'Can manage' permissions.

P.S. I'm using Azure Databricks.

Hello! Yes, I do. I requested the permission of Contributor, on the Databricks service, on the Azure Portal, and now this Tip appeared. How can I write to files in a repository?

Hi, Could you please check on cluster-level permissions and let us know if it helps?

Please refer: https://docs.databricks.com/security/access-control/cluster-acl.html#cluster-level-permissions

Hi Ruben!
I am facing exactly the same error running a similar approach when using runtime 16.2 ML. I didn't have this issue when using runtime 12.2 LTS ML or 13.3 ML. Did you find a solution?

Many thanks!
