Images ¶

Rasa NLU docker images are provided for different backends:

spacy: If you use the pretrained_embeddings_spacy pipeline
tensorflow: If you use the supervised_embeddings pipeline
mitie: If you use the mitie pipeline
bare: If you want to take a base image and enhance it with your custom dependencies
full (default): If you use components from different pre-defined pipelines and want to have everything included in the image.

Note

For the tensorflow and the full image a x86_64 CPU with AVX support is required.

Training NLU ¶

To train a NLU model you need to mount two directories into the Docker container:

a directory containing your project which in turn includes your NLU configuration and your NLU training data
a directory which will contain the trained NLU model

docker run \
    -v <project_directory>:/app/project \
    -v <model_output_directory>:/app/model \
    rasa/rasa_nlu:latest \
    run \
        python -m rasa_nlu.train \
            -c /app/project/<nlu configuration>.yml \
            -d /app/project/<nlu data> \
            -o /app/model \
            --project <nlu project name>

Running NLU with Rasa Core ¶

See this guide which describes how to set up all Rasa components as Docker containers and how to connect them.

Running NLU as Standalone Server ¶

To run NLU as server you have to

mount a directory with the trained NLU models
expose a port

docker run \
    -p 5000:5000 \
    -v <directory with nlu models>:/app/projects \
    rasa/rasa_nlu:latest \
    start \
        --path /app/projects
        --port 5000

You can then send requests to your NLU server as it is described in the HTTP API, e.g. if it is running on the localhost:

curl --request GET \
     --url 'http://localhost:5000/parse?q=Hello%20world!'
