how to use it

Using the class path to the place where you should given a component name in config.yaml. This is a feature of rasa, see here for more document from rasa official document.

For example, your config.yml can be:

language: "zh"

pipeline:
  - name: "rasa_contrib.nlu..TensorflowNLP"
  - name: "rasa_contrib.nlu..BilstmCrfTensorFlowEntityExtractor"
    max_steps: 600
  - name: "rasa_contrib.nlu.TextCnnTensorFlowClassifier"
    max_steps: 600

policies:
  - name: MemoizationPolicy
  - name: rasa_contrib.core.StackedBilstmTensorFlowPolicy

rasa_contrib's Issues

problem serving model

steps to reproduce:

1. rasa train nlu
   --config ./configs/$agent/rasa_config.yml
   --nlu ./core/$agent/training_data.json
   --fixed-model-name core_$agent
   --out ./models
   --verbose
   2 . rasa run -v -m models --enable-api --port 5000
