New features and improvements

  • Updated to tensorflow 1.13.1 and spacy 2.1 (this also makes Ludwig compatible with Python 3.7)
  • Added an initial integration with Comet.ml
  • Added support for text preprocessing of additional languages: Italian, Spanish, German, French, Portuguese, Dutch, Greek and Multi-language (Fature Request #251).
  • Added skip_save_progress, skip_save_model and skip_save_log parameters
  • Improved the default parameters of the image feature (this may make previously trained models including image features not compatible. If that is the case retrain your model)
  • Added PassthroughEncoder
  • Added eval_batch_size parameter
  • Added sanity checks for model definitions, with improved error messages
  • Add Dockerfile for running Ludwig on a CPU
  • Added clip parameter to numerical output features
  • Added a full MNIST training example, a fraud detection example and a more complex regression example on fuel consumption
