Summary

  • Prints a warning to stderr when run_evaluator iterates zero data rows
  • Prevents users from silently landing on an empty experiment in the UI with no indication of what went wrong
  • No change to control flow — experiment still runs (just empty), warning is informational

Test plan

  • New test: test_run_evaluator_empty_dataset_warns — asserts warning appears in stderr when data=[]
  • All existing test_framework.py tests unaffected

warn when Eval() receives an empty dataset

Print a warning to stderr when no data rows are found after iterating
the dataset, so users get an actionable signal instead of silently
landing on an empty experiment in the UI.

Can we switch this to use eprint? We might also want to use bcolors.WARNING.

Summary
  • Prints a warning to stderr when run_evaluator iterates zero data rows
  • Prevents users from silently landing on an empty experiment in the UI with no indication of what went wrong
  • No change to control flow — experiment still runs (just empty), warning is informational
Test plan
  •  New test: test_run_evaluator_empty_dataset_warns — asserts warning appears in stderr when data=[]
  •  All existing test_framework.py tests unaffected

warn when Eval() receives an empty dataset

Print a warning to stderr when no data rows are found after iterating
the dataset, so users get an actionable signal instead of silently
landing on an empty experiment in the UI.

Can we switch this to use eprint? We might also want to use bcolors.WARNING.
