Kedro+experiment+tracking+failed+error+DataSetError+dataset+metrics+not

Not specified by the original author.

TL;DR

Register the metrics as a Kedro dataset or log them through the experiment tracking hooks Kedro expects: Kedro experiment tracking only records datasets declared for tracking, so add the metrics dataset to the catalog with the tracking handler, or use the MLflow integration dataset type. Kedro does not discover metrics by name. A metrics dictionary produced by a node is just data until the catalog declares how it should be tracked.

Kedro experiment tracking failed error "DataSetError: dataset metrics not configured"

Use this when

• The check or run fails with this symptom: Kedro experiment tracking fails with DataSetError dataset metrics not configured.
• You are working on a Kedro project using experiment tracking for node metrics and the failure repeats on the same data or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• A project tracking through a custom hook, where the error means the hook expects a different catalog entry name.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Open the catalog and find the metrics entry the pipeline produces. Verify: the entry exists as a plain dataset, or is missing
2. Check which experiment tracking integration the project uses and the dataset type it requires. Verify: the required dataset configuration is known
3. Declare the metrics dataset with the tracking dataset type for that integration. Verify: the catalog loads with the tracking dataset in place
4. Run the pipeline. Verify: metrics appear in the tracking store for the run
5. Confirm the run in the tracking UI carries the expected metric names. Verify: every node metric is recorded

The variant naming the failing stage or tool directly.

Compatibility: Kedro experiment tracking integrations, catalog dataset configuration

Why it happens

Kedro catalog entries are explicit contracts. Experiment tracking integrations read a specific dataset type, and a metrics output saved as a generic dataset, often copied from an example without the tracking type, produces this error the first time the pipeline runs end to end.

Edge cases / pitfalls

• Catalog environments override entries per environment; a fix in the base catalog can be shadowed by a local override.
• Metric names with dots or slashes can break some tracking stores; keep names simple at the node.

TL;DR

Unlock or relocate the session store before exporting: Kedro session data is held in a store that another live session has locked, so close the competing session, or export from a copy of the project session store taken when no session is active. Kedro sessions record run data as they go, and the store allows one active writer. An export that arrives while a session holds the store gets a lock error that looks like missing data.

when agent tried to export Kedro experiment metrics agent failed error session store locked

Use this when

• The check or run fails with this symptom: an agent tries to export Kedro experiment metrics and fails with a session store locked error.
• You are working on an agent workflow exporting Kedro session or experiment metrics after pipeline runs and the failure repeats on the same data or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• A store left locked by a crashed session, which needs the stale lock cleared after confirming no process is alive.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Identify the process holding the session store, from the lock details or the running processes. Verify: a live session or a stale lock is confirmed
2. If a session is live, wait for it to finish or export after it closes. Verify: the lock releases with the session
3. If the holder is gone, clear the stale lock following the store layout for the Kedro version in use. Verify: the store opens for reading
4. Run the export. Verify: metrics for the recorded sessions are written out
5. Schedule exports after pipeline completion in the workflow. Verify: exports stop racing live sessions

kedro session lock export fix

The variant naming the failing stage or tool directly.

Compatibility: Kedro session stores and experiment exports, agent workflow scheduling

Why it happens

Kedro writes session records during a run, and exports are usually bolted on afterwards by a different tool or agent that does not know a session is still open, especially when a notebook kernel keeps one alive. The lock is the store protecting the records the export wants to read.

Edge cases / pitfalls

• Notebook kernels hold sessions open invisibly; check for kernels before declaring a lock stale.
• Copying a locked store mid-write can produce a torn export; copy only after the lock clears.
