Malaya is a Natural-Language-Toolkit library for bahasa Malaysia, powered by Tensorflow and PyTorch.


Proper documentation is available at https://malaya.readthedocs.io/

Installing from the PyPI#

$ pip install malaya

It will automatically install all dependencies except for Tensorflow and PyTorch. So you can choose your own Tensorflow CPU / GPU version and PyTorch CPU / GPU version.

Only Python >= 3.6.0, Tensorflow >= 1.15.0, and PyTorch >= 1.10 are supported.

Development Release#

Install from master branch,

$ pip install git+https://github.com/huseinzol05/malaya.git

We recommend to use virtualenv for development.
