Adk evaluation failing with: "AttributeError: 'float' object has no attribute 'item'"

[iperdomocabrera]

Hi all,

I'm attempting to run ADK evaluation on my agent but I'm encountering the following error: "AttributeError: 'float' object has no attribute 'item'". Here are the details:

• I'm using google-adk version 1.1.1, but I've also tried 0.0.4 and 1.0.0 with the same error.

• The eval-set I'm using was generated via ADK Web.

• I've executed the tests using both pytest and the adk eval CLI, and both produce the same results.

• The error appears to originate from the response_evaluator, specifically this line.

self = <google.adk.evaluation.response_evaluator.ResponseEvaluator object at 0x00000141C47D2030>
eval_result = EvalResult(summary_metrics={'row_count': 1, 'rouge_1/mean': nan, 'rouge_1/std': np.float64(nan)}, metrics_table=      ...e_1/score
0  {   "audit_transaction": {     "request_docume...  ...          None

[1 rows x 6 columns], metadata=None)

   def _get_score(self, eval_result) -> float:
>     return eval_result.summary_metrics[f"{self._metric_name}/mean"].item()
E     AttributeError: 'float' object has no attribute 'item'

..\.env\Lib\site-packages\google\adk\evaluation\response_evaluator.py:120: AttributeError

• These are the files Im using to run the evaluation including the test output:
  test_config.json.txt
  analyze_agent.test.json.txt
  test_analyze_agent.py.txt
  TestResults.txt

Any guidance would be appreciated!
