Changed

• Drop support for Python 3.4 and below

0.7.2

0.7.1

Fixed

• Fix installation issues with the centralised meta information and the build process

0.7.0

Fixed

• Fix indices format in RandomForestClassifier (#41, thanks @apasanen)

Added

• Add Python 3.7 with Xenial to CI for testing
• Add PyTest for extended testing (see pytest.ini)
• Add useful Makefile tasks with dependency handling (see Makefile):
  • install.environment to install a conda environment
  • install.requirements to install all pip requirements
  • make link to install porter (cli) to the command line
  • make open.examples to start a local jupyter server
  • make stop.examples to stop the started jupyter server
  • make test to run all unittests in tests
  • make lint to run pylint over sklearn_porter
  • make jupytext to generate the notebooks from Python sources

Changed

• Core:
  • Merge all meta information to sklearn_porter/pypi.json
• CI and requirements:
  • Remove conda from CI
  • Clear and split pip requirements into three parts:
    • requirements.txt for library requirements
    • requirements.examples.txt for examples requirements
    • requirements.development.txt for development requirements
  • Update extended requriements (e.g. GCC, PHP, ...)
• Utils:
  • Refactor class sklearn_porter.utils.Shell to remove redundancy
  • Refactor CLI with a bunch of improvements (grouped arguments, use of console scripts)
• Testing:
  • Change web server port for testing from 8080 to 8713 (because of collusion with the default port of Jenkins)
  • Remove class tests.utils.DependencyChecker, instead use sklearn_porter.utils.Environment
  • Remove class tests.utils.Timer, instead use --durations=0 of PyTest

0.6.2

Fixed

0.6.1

Added

• Add new estimator:
