What is DELTA?

DELTA is a cutting-edge platform designed for natural language and speech processing. Built with TensorFlow and Python 3, it offers streamlined experiences for deploying and developing models for both research and real-world applications. Whether you are working on text classification or speech recognition, DELTA makes it seamless!

What Can DELTA Do?

• Easy-to-use: Train models with just one command across various NLP and speech tasks.
• Easy-to-deploy: Integrated model graphs ensure consistency from training to serving.
• Easy-to-develop: Modular components allow you to build state-of-the-art models effortlessly.

Installation

To get DELTA up and running, follow these simple installation methods based on your needs:

• From Pip (for NLP tasks).
• From Source Code (NLP and Speech tasks).
• From Docker (for deployments).

Install from Pip

To install DELTA using pip, we recommend creating a Conda or virtual environment. Here’s how:

bash
conda create -n delta-pip-py3.6 python=3.6
conda activate delta-pip-py3.6
pip install tensorflow
pip install delta-nlp

Follow the examples provided in the documentation to train NLP models post-installation.

Install from Source Code

To install DELTA from the source, make sure you have Conda installed. This method allows for more customization:

shell
cd tools
./install/install-delta.sh nlp [cpugpu]

To install NLP and speech, use:

shell
cd tools
KALDI=yourpathtoKaldi ./install/install-delta.sh full [cpugpu]

Quick Start

Once installation is complete, you can jump straight into using DELTA. Examples for numerous tasks are organized in the egs directory. For instance, to download the CONLL2003 data set and train a named entity recognition (NER) model, run:

shell
pushd egs/conll2003/seq_label/v1
./run.sh
popd
python3 delta/main.py --cmd train --config egs/conll2003/seq_label/v1/config/seq-label.yml

Modeling and Deployment

To train and evaluate your model, DELTA offers various commands. Example:

shell
python3 delta/main.py --cmd train_and_eval --config your_configuration_file.yml

For deployment, follow scripts under the .dpl directory to convert models to various formats.

Troubleshooting

If you encounter issues during installation or runtime, consider the following troubleshooting steps:

• Ensure all dependencies (including TensorFlow and Conda) are correctly installed.
• Double-check your environment activation commands.
• If the issue persists, refer to the FAQ section for detailed help.
