Comprehensive MLflow Traces CLI for managing trace data, assessments, and metadata.
This module provides a complete command-line interface for working with MLflow traces,
including search, retrieval, deletion, tagging, and assessment management. It supports
both table and JSON output formats with flexible field selection capabilities.
AVAILABLE COMMANDS:
search Search traces with filtering, sorting, and field selection
get Retrieve detailed trace information as JSON
delete Delete traces by ID or timestamp criteria
set-tag Add tags to traces
delete-tag Remove tags from traces
log-feedback Log evaluation feedback/scores to traces
log-expectation Log ground truth expectations to traces
get-assessment Retrieve assessment details
update-assessment Modify existing assessments
delete-assessment Remove assessments from traces
EXAMPLE USAGE:
# Search traces across multiple experiments
mlflow traces search --experiment-ids 1,2,3 --max-results 50
# Filter traces by status and timestamp
mlflow traces search --experiment-ids 1 \
--filter-string "status = 'OK' AND timestamp_ms > 1700000000000"
# Get specific fields in JSON format
mlflow traces search --experiment-ids 1 \

mlflow traces get --trace-id tr-1234567890abcdef
# Log feedback to a trace
mlflow traces log-feedback --trace-id tr-abc123 \
--name relevance --value 0.9 \
--source-type HUMAN --source-id reviewer@example.com \
--rationale "Highly relevant response"
# Delete old traces
mlflow traces delete --experiment-ids 1 \

JSONPath utilities for navigating and manipulating nested JSON structures.
This module provides a simplified JSONPath-like implementation without adding
external dependencies to MLflow. Instead of using a full JSONPath library,
we implement a lightweight subset focused on trace data navigation using
dot notation with wildcard support.
The implementation supports:
- Dot notation path traversal (e.g., "info.trace_id")
- Wildcard expansion (e.g., "info.assessments.*")
- Array/list navigation with numeric indices
- Structure-preserving filtering
- Path validation with helpful error messages
This approach keeps MLflow dependencies minimal while providing the essential
functionality needed for trace field selection and data manipulation.
Note: This is NOT a complete JSONPath implementation. It's a custom solution
tailored specifically for MLflow trace data structures.

"""
A versioned scorer entity that represents a specific version of a scorer within an MLflow
experiment.
Each ScorerVersion instance is uniquely identified by the combination of:
- experiment_id: The experiment containing the scorer
- scorer_name: The name of the scorer
- scorer_version: The version number of the scorer
The class provides access to both the metadata (name, version, creation time) and the actual
scorer implementation through the serialized_scorer property, which deserializes the stored
scorer data into a usable SerializedScorer object.
Args:
experiment_id (str): The ID of the experiment this scorer belongs to.
scorer_name (str): The name identifier for the scorer.
scorer_version (int): The version number of this scorer instance.
serialized_scorer (str): JSON-serialized string containing the scorer's metadata and code.
creation_time (int): Unix timestamp (in milliseconds) when this version was created.
scorer_id (str, optional): The unique identifier for the scorer.
Example:
.. code-block:: python
from mlflow.entities.scorer import ScorerVersion
# Create a ScorerVersion instance
scorer_version = ScorerVersion(
experiment_id="123",
scorer_name="accuracy_scorer",

"""
Create a custom prompt judge that evaluates inputs using a template.
Args:
name: Name of the judge, used as the name of returned
:py:class:`mlflow.entities.Feedback` object.
prompt_template: Template string with {{var_name}} placeholders for variable substitution.
Should be prompted with choices as outputs.
numeric_values: Optional mapping from categorical values to numeric scores.
Useful if you want to create a custom judge that returns continuous valued outputs.
Defaults to None.
model: {{ model }}
Returns:
A callable that takes keyword arguments mapping to the template variables
and returns an mlflow :py:class:`mlflow.entities.Feedback`.
Example prompt template:
.. code-block::
You will look at the response and determine the formality of the response.
<request>{{request}}</request>
<response>{{response}}</response>
You must choose one of the following categories.
[[formal]]: The response is very formal.
[[semi_formal]]: The response is somewhat formal. The response is somewhat formal if the
response mentions friendship, etc.
[[not_formal]]: The response is not formal.
Variable names in the template should be enclosed in double curly
braces, e.g., `{{request}}`, `{{response}}`. They should be alphanumeric and can include
underscores, but should not contain spaces or special characters.
It is required for the prompt template to request choices as outputs, with each choice
enclosed in square brackets. Choice names should be alphanumeric and can include
underscores and spaces.

"""
Retrieve a specific registered scorer by name and optional version.
This function retrieves a single Scorer instance from the specified experiment. If no
version is specified, it returns the latest (highest version number) scorer with the
given name.
Args:
name (str): The name of the registered scorer to retrieve. This must match exactly
with the name used during scorer registration.
experiment_id (str, optional): The ID of the MLflow experiment containing the scorer.
If None, uses the currently active experiment as determined by
:func:`mlflow.get_experiment_by_name` or :func:`mlflow.set_experiment`.
version (int, optional): The specific version of the scorer to retrieve. If None,
returns the scorer with the highest version number (latest version).
Returns:
Scorer: A Scorer object representing the requested scorer.
Raises:
mlflow.MlflowException: If the scorer with the specified name is not found in the
experiment, if the specified version doesn't exist, if the experiment doesn't exist,
or if there are issues with the backend store connection.
Example:
.. code-block:: python
from mlflow.genai.scorers import get_scorer
# Get the latest version of a scorer
latest_scorer = get_scorer(name="accuracy_scorer")
# Get a specific version of a scorer
v2_scorer = get_scorer(name="safety_scorer", version=2)
# Get a scorer from a specific experiment
scorer = get_scorer(name="relevance_scorer", experiment_id="123")
Note:
- When no version is specified, the function automatically returns the latest version
- This function works with both OSS MLflow tracking backend and Databricks backend.
- For Databricks backend, versioning is not supported, so the version parameter
should be None.

"""
Delete a registered scorer from the MLflow experiment.
This function permanently removes scorer registrations.
The behavior of this function varies depending on the backend store and version parameter:
**OSS MLflow Tracking Backend:**
- Supports versioning with granular deletion options
- Can delete specific versions or all versions of a scorer by setting `version`
parameter to "all"
**Databricks Backend:**
- Does not support versioning
- Deletes the entire scorer regardless of version parameter
- `version` parameter must be None
Args:
name (str): The name of the scorer to delete. This must match exactly with the
name used during scorer registration.
experiment_id (str, optional): The ID of the MLflow experiment containing the scorer.
If None, uses the currently active experiment as determined by
:func:`mlflow.get_experiment_by_name` or :func:`mlflow.set_experiment`.
version (int | str | None, optional): The version(s) to delete:
For OSS MLflow tracking backend: if `None`, deletes the latest version only, if version
is an integer, deletes the specific version, if version is the string 'all', deletes
all versions of the scorer
For Databricks backend, the version must be set to `None` (versioning not supported)
Raises:
mlflow.MlflowException: If the scorer with the specified name is not found in
the experiment, if the specified version doesn't exist, or if versioning
is not supported for the current backend.
Example:
.. code-block:: python
from mlflow.genai.scorers import delete_scorer
# Delete the latest version of a scorer from current experiment
delete_scorer(name="accuracy_scorer")
# Delete a specific version of a scorer
delete_scorer(name="safety_scorer", version=2)
