  File "/kaggle/working/bigcode-evaluation-harness/main.py", line 412, in <module>
    main()
  File "/kaggle/working/bigcode-evaluation-harness/main.py", line 396, in main
    results[task] = evaluator.evaluate(
  File "/kaggle/working/bigcode-evaluation-harness/bigcode_eval/evaluator.py", line 107, in evaluate
    results = task.process_results(generations, references)
  File "/kaggle/working/bigcode-evaluation-harness/bigcode_eval/tasks/apps.py", line 119, in process_results
