ICASSP

✓ from basic_pitch import ICASSP_2022_MODEL_PATH

✗ from basic_pitch import ICASSP

Model constant is named ICASSP_2022_MODEL_PATH, not ICASSP.

Transcribe an audio file to MIDI using the default ICASSP 2022 model.

import os from basic_pitch.inference import predict from basic_pitch import ICASSP_2022_MODEL_PATH model_path = ICASSP_2022_MODEL_PATH audio_path = 'example.wav' model_output, midi_data, note_events = predict(model_path, audio_path) midi_data.write('output.mid')

Debug

Known issues

breakingTensorFlow 2.11+ dropped GPU support for some systems; use tensorflow-cpu or downgrade to tensorflow<2.11.

fix

pip install tensorflow-cpu==2.10 or use CPU-only path.

affects: >=0.4.0

gotchaThe predict function returns a tuple: (model_output, midi_data, note_events). midi_data is a pretty_midi.PrettyMIDI object; call .write() to save.

fix

Always capture three return values.

affects: all

deprecatedImporting from basic_pitch.inference directly is stable, but internal modules like basic_pitch.model may change.

fix

Use basic_pitch.inference for public API.

affects: 0.4.0
