mlflow - how to delete and restart database of experiments and models

[SS]

I was able to run this experiment successfully at first.

After many successful retries with my own data, mlflow stopped working and gave errors for almost every function in it. 

Is this because the mlflow server is broken - where is this data stored and how can i restart the mlflow database?
Also, different functions in mlflow seem to work or not at different times of the day/week.

Hello @SS 

MLflow uses Lakehouse storage to save experiment data and artifacts

Try Locate the directory where MLflow experiments are stored (e.g., `/lakehouse/default/Files/Experiments`).

Manually delete the folder(s) associated with your experiments or models.

Thanks Nilendra.

I can see the Experiment and multiple runs in it, and am able to delete them. It didn't fix the exception mlflow keeps throwing around 'BAD_REQUEST'.

Speaking of folders, what is my relative or absolute path from a notebook in a Fabric workspace?

I tried using the makedirectory and listfile commands at https://learn.microsoft.com/en-us/fabric/data-engineering/notebook-utilities with directory = ‘Files/TEMP’ or ‘Tables/’ and both gave errors.
