Release version 0.4.0 of OpenL3.

  • Upgraded to tensorflow>=2.0.0. Tensorflow is now included as a dependency because of dual CPU-GPU support.
  • Upgraded to kapre>=0.3.5. Reverted magnitude scaling method to match kapre<=0.1.4 as that's what the model was trained on.
  • Removed Python 2/3.5 support as they are not supported by Tensorflow 2 (and added 3.7 & 3.8)
  • Add librosa frontend, and allow frontend to be configurable between kapre and librosa
    • Added frontend='kapre' parameter to get_audio_embedding, process_audio_file, and load_audio_embedding_model
    • Added audio_frontend='kapre' parameter to process_video_file and the CLI
    • Added frontend='librosa' flag to load_audio_embedding_model for use with a librosa or other external frontend
    • Added a openl3.preprocess_audio function that computes the input features needed for each frontend
  • Model .h5 no longer have Kapre layers in them and are all importable from tf.keras
  • Made skimage and moviepy.video.io.VideoFileClip import VideoFileClip use lazy imports
  • Added new regression data for both Kapre 0.3.5 and Librosa
  • Parameterized some of the tests to reduce duplication
  • Added developer helpers for regression data, weight packaging, and .h5 file manipulation
