Changes

Bug fix

• ALSOption allows float type alpha not a int type.
• Fixed CUDA compilation bug
• Changed module name (aux -> _aux) to avoid conflict with windows OS's reserved keyword
  • from aurochs.misc.aux import xxx would not work anymore
  • Instead, use from aurochs.misc import aux; aux.xxx or from aurochs.misc._aux import xxx

Misc

• Changed build backed (poetry -> setuptools)
• Changed submodule path for Eigen and its version(to 3.4)
• Removed unnecessary imports and directives from cython sources
• Removed useless dependency and CLI
  • fire & absl-py
• Add Github acntions CI pipleline for building wheels
  • Only supports Linux & MacOS wheel with x86_64 architecture

• Build wheels on pypi are fixed

• Added new algorithm WARP (Collaborative Metric Learning)

• Add new training algorithm ials++ for learning ALS Model

• Delete tensorboard, hyperopt

  • Optimizable is replaced now
  • train methods of models now take training_callback e.g.) https://github.com/kakao/buffalo/blob/54c97fd300c2615eb53fcfd4fdc7879b98f19703/buffalo/algo/als.py#L144
