  Neural Monkey

Neural Sequence Learning Using TensorFlow

The Neural Monkey package provides a higher level abstraction for sequential neural network models, most prominently in Natural Language Processing (NLP). It is built on TensorFlow. It can be used for fast prototyping of sequential models in NLP which can be used e.g. for neural machine translation or sentence classification.

The higher-level API brings together a collection of standard building blocks (RNN encoder and decoder, multi-layer perceptron) and a simple way of adding new building blocks implemented directly in TensorFlow.

Usage

neuralmonkey-train <EXPERIMENT_INI>
neuralmonkey-run <EXPERIMENT_INI> <DATASETS_INI>
neuralmonkey-server <EXPERIMENT_INI> [OPTION] ...
neuralmonkey-logbook --logdir <EXPERIMENTS_DIR> [OPTION] ...

Installation

• You need Python 3.6 (or higher) to run Neural Monkey.

• When using virtual environment, execute these commands to install the Python dependencies:

  $ source path/to/virtualenv/bin/activate
  
  # For GPU-enabled version
  (virtualenv)$ pip install --upgrade -r requirements-gpu.txt
  
  # For CPU-only version
  (virtualenv)$ pip install --upgrade -r requirements.txt
  

• If you are using the GPU version, make sure that the LD_LIBRARY_PATH environment variable points to lib and lib64 directories of your CUDA and CuDNN installations. Similarly, your PATH variable should point to the bin subdirectory of the CUDA installation directory.

• If the training crashes on an unknown dependency, just install it with pip. Remember to keep your virtual environment up-to-date with the package requirements file, which may be changed over time. To update the dependencies, re-run the pip install command from above (pay attention to the distinction between GPU and non-GPU versions).

Getting Started

There is a tutorial that you can follow, which gives you the overwiev of how to design your experiments with Neural Monkey.

Documentation

You can find the API documentation of this package here. The documentation files are generated from docstrings using autodoc and Napoleon extensions to the Python documentation package Sphinx. The docstrings should follow the recommendations in the Google Python Style Guide. Additional details on the docstring formatting can be found in the Napoleon documentation as well.
