Overview

NeuronBlocks is a NLP deep learning modeling toolkit that helps engineers/researchers to build end-to-end pipelines for neural network model training for NLP tasks. The main goal of this toolkit is to minimize developing cost for NLP deep neural network model building, including both training and inference stages.

NeuronBlocks consists of two major components: Block Zoo and Model Zoo.

• In Block Zoo, we provide commonly used neural network components as building blocks for model architecture design.
• In Model Zoo, we provide a suite of NLP models for common NLP tasks, in the form of JSON configuration files.

Language Supported

• English
• Chinese

NLP Tasks Supported

• Sentence Classification
• Sentiment Analysis
• Question Answering Matching
• Textual Entailment
• Slot tagging
• Machine Reading Comprehension
• Knowledge Distillation for Model Compression
• More on-going

Toolkit Usage

Users can either pick existing models (config files) in Model Zoo to start model training or create new models by leveraging neural network blocks in Block Zoo just like playing with Lego.

Installation

Note: NeuronBlocks requires Python 3.6 and above.

1. Clone this project.

   git clone https://github.com/Microsoft/NeuronBlocks
   

2. Install Python packages in requirements.txt by the following command.

   pip install -r requirements.txt
   

3. Install PyTorch (NeuronBlocks supports PyTorch 0.4.1 and above).

   For Linux, run the following command:

   pip install "torch>=0.4.1"
   

   For Windows, we suggest you to install PyTorch via Conda by following the instruction of PyTorch.

Quick Start

Get started by trying the given examples. Both Linux/Windows, GPU/CPU are supported. For Windows, we suggest you to use PowerShell instead of CMD.

Tips: in the following instruction, PROJECTROOT denotes the root directory of this project.

# train
cd PROJECT_ROOT
python train.py --conf_path=model_zoo/demo/conf.json

# test
python test.py --conf_path=model_zoo/demo/conf.json

# predict
python predict.py --conf_path=model_zoo/demo/conf.json

For prediction, NeuronBlocks have two modes: Interactive and Batch.

• Interactive Prediction Mode: The interactive mode provides interactive interface, users can input case according to corresponding prompt message and get realtime prediction result from trained model, and input "exit" to exit interactive interface.

# use the above example
# interactive prediction
python predict.py --conf_path=model_zoo/demo/conf.json --predict_mode='interactive'

• Batch Prediction Mode: For batched cases prediction, NeuronBlocks provides batch prediction mode which receives a cases file as input and write the prediction results in the prediction file.

# use the above example
# batch prediction
python predict.py --conf_path=model_zoo/demo/conf.json --predict_mode='batch' --predict_data_path=dataset/demo/predict.tsv

For more details, please refer to Tutorial.md and Code documentation.

Who should consider using NeuronBlocks

Engineers or researchers who face the following challenges when using neural network models to address NLP problems:

• Many frameworks to choose and high framework studying cost.
• Heavy coding cost. A lot of details make it hard to debug.
• Fast Model Architecture Evolution. It is difficult for engineers to understand the mathematical principles behind them.
• Model Code optimization requires deep expertise.
• Model Platform Compatibility Requirement. It requires extra coding work for the model to run on different platforms, such as Linux/Windows, GPU/CPU.

The advantages of leveraging NeuronBlocks for NLP neural network model training includes:

• Model Building: for model building and parameter tuning, users only need to write simple JSON config files, which greatly minimize the effort of implementing new ideas.

• Model Sharing It is super easy to share models just through JSON files, instead of nasty codes. For different models or tasks, our users only need to maintain one single centralized source code base.

• Code Reusability: Common blocks can be easily shared across various models or tasks, reducing duplicate coding work.

• Platform Flexibility: NeuronBlocks can run both on Linux and Windows machines, using both CPU and GPU. It also supports training on GPU platforms like Philly and PAI.

  	CPU inference	Single-GPU inference	Multi-GPU inference
  CPU train	✓	✓	✓
  Single-GPU train	✓	✓	✓
  Multi-GPU train	✓	✓	✓

• Model Visualization: A model visualizer is provided for visualization and configure correctness checking, which helps users to visualize the model architecture easily during debugging.

• Extensibility: NeuronBlocks is extensible, allowing users to contribute new blocks or contributing novel models (JSON files).

Contribute

NeuronBlocks operates in an open model. It is designed and developed by STCA NLP Group, Microsoft. Contributions from academia and industry are also highly welcome. For more details, please refer to Contributing.md.

Ongoing Work and Call for Contributions

Anyone who are familiar with are highly encouraged to contribute code.

• Knowledge Distillation for Model Compression. Knowledge distillation for heavy models such as BERT, OpenAI Transformer. Teacher-Student based knowledge distillation is one common method for model compression.
• Multi-Lingual Support
• NER Model Support
• Multi-Task Training Support
