Warning!

Puhti and Mahti are being decommissioned in stages, and their storage areas will become fully unavailable from 15 October 2026. Clean up unnecessary files and move any data you need to keep by 31 August 2026. See the Roihu data migration guide for instructions on transferring your data to Roihu.

Puhti scratch is very full: keep only active data there and move or delete everything else. No new Puhti scratch quota will be granted.

MLflow

The MLflow app launches the MLflow tracking UI on a compute node.

To launch it select where the MLflow files are stored. This is typically either:

  • a directory like /scratch/<project>/mlruns/
  • an SQLite database like sqlite:////scratch/<project>/mlruns.db

The default resource settings should be fine for most cases.

Also checkout the MLflow section in our Machine learning guide.
