Install from the source code

To install from the source code, We use conda to install required packages. Please install conda if you do not have it in your system.

Also, we provide two options to install DELTA, nlp version or full version. nlp version needs minimal requirements and only installs NLP related packages:

# Run the installation script for NLP version, with CPU or GPU.
cd tools
./install/install-delta.sh nlp [cpu|gpu]

Note: Users from mainland China may need to set up conda mirror sources, see ./tools/install/install-delta.sh for details.

If you want to use both NLP and speech packages, you can install the full version. The full version needs Kaldi library, which can be pre-installed or installed using our installation script.

cd tools
# If you have installed Kaldi
KALDI=/your/path/to/Kaldi ./install/install-delta.sh full [cpu|gpu]
# If you have not installed Kaldi, use the following command
# ./install/install-delta.sh full [cpu|gpu]

To verify the installation, run:

# Activate conda environment
conda activate delta-py3.6-tf2.0.0
# Or use the following command if your conda version is < 4.6
# source activate delta-py3.6-tf2.0.0

# Add DELTA enviornment
source env.sh

# Generate mock data for text classification.
pushd egs/mock_text_cls_data/text_cls/v1
./run.sh
popd

# Train the model
python3 delta/main.py --cmd train_and_eval --config egs/mock_text_cls_data/text_cls/v1/config/han-cls.yml
