GOAL
Update the exploratory notebook to reflect a new signal-processing word-boundary detection method, showing its improvement over the current app alignment and old proportional splitter on labeled comma-audio data.
- +0Prompt · +0Update notebook 03 and the benchmark test to reflect a new signal_word_timestamps method that beats current app alignment (1/13) and old proportional splitter (0/13) on labeled word-boundary data.
- +0mAgent did · +0mInspected notebook structure and app.py, ran the benchmark test suite in a plain python3 environment, hit a pytest collection error (missing UI deps), switched to using the repo's .venv/bin/python which passed 8 tests.
- +1mAgent did · +1mPulled exact aggregate numbers from the benchmark code path, edited notebook cells 7-13 to add the new 'Signal word-boundary detector' method, refreshed the expected-results table and interpretation notes to show 0/13 -> 1/13 -> 12/13 progression.
- +2mAgent did · +2mValidated notebook JSON, re-ran test_word_boundary_benchmark.py (8 passed) and test_reading_evaluation.py (24 passed), confirmed git diff scoped to notebook 03 only.
- +4mPrompt · +4mThe notebook crashes the kernel from the first cell with a TqdmWarning and kernel crash error.
- +4mFail · +4mNotebook kernel crashed on first cell execution after the earlier edit.
- +4mAgent did · +4mDiagnosed that notebook's setup cell imported app.py, pulling in Gradio/Modal/local inference deps just to get small helper functions; inlined lightweight text/audio helpers directly into the notebook so the first cell no longer imports app, keeping current-app-alignment as a cached baseline row.
- +6mAgent did · +6mExecuted all notebook code cells in order to verify no crashes, confirmed 12/13, 1/13, 0/13 summary reproduced, re-ran both test files (8 and 24 passed) and validated JSON and diff scope.
- +7mOutcome · +7mNotebook 03 fixed to avoid importing app.py in its first cell; test_word_boundary_benchmark.py (8 passed) and test_reading_evaluation.py (24 passed) still green; benchmark story documented as 0/13 -> 1/13 -> 12/13.
VERDICT
Next time I'd mention upfront that the notebook shouldn't import the full app.py stack, since that's what ended up crashing my kernel later. The fix that actually mattered was inlining the lightweight helpers instead of pulling in Gradio/Modal just for text/audio utilities — that's what let the notebook run cleanly from cell one while keeping the benchmark numbers intact.
