# Run Experiment Evaluations

> Run evaluations on experiment results

## Overview

Execute evaluation metrics on experiment results to assess model performance.

## Method Signature

```python theme={"system"}
# Synchronous
client.experiments.run_experiment_evals(
    experiment_id: str,
    evaluator_ids: List[str],
    run_id: Optional[str] = None
) -> Dict[str, Any]

# Asynchronous
await client.experiments.run_experiment_evals(
    experiment_id: str,
    evaluator_ids: List[str],
    run_id: Optional[str] = None
) -> Dict[str, Any]
```

## Parameters

<ParamField path="experiment_id" type="string" required>
  The unique identifier of the experiment
</ParamField>

<ParamField path="evaluator_ids" type="List[str]" required>
  List of evaluator IDs to run on the experiment results
</ParamField>

<ParamField path="run_id" type="string" optional>
  Specific run ID to evaluate. If not provided, evaluates the latest run
</ParamField>

## Returns

Returns a dictionary containing the evaluation results and metrics.

## Example

```python theme={"system"}
from keywordsai import KeywordsAI

client = KeywordsAI(api_key="your-api-key")

# Run evaluations on latest experiment run
evaluator_ids = ["eval_accuracy", "eval_relevance"]

result = client.experiments.run_experiment_evals(
    experiment_id="exp_123",
    evaluator_ids=evaluator_ids
)

print(f"Evaluation status: {result['status']}")
print(f"Metrics: {result['metrics']}")

# Run evaluations on specific run
result = client.experiments.run_experiment_evals(
    experiment_id="exp_123",
    evaluator_ids=evaluator_ids,
    run_id="run_456"
)
```

## Error Handling

```python theme={"system"}
try:
    result = client.experiments.run_experiment_evals(
        experiment_id="exp_123",
        evaluator_ids=["eval_accuracy"]
    )
except Exception as e:
    print(f"Error running evaluations: {e}")
```
