Hardened machine-learning stack: JupyterHub notebooks, the MLflow tracking server and model registry, and Label Studio for data labeling, wired together in one install.
Version
The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.
