Step 10: Deploy Trained ModelsΒΆ
Once your application has been built, MindMeld makes it easy to test locally. In Step 4, we created an application container for your dialogue state handler logic. This was in the __init__.py file in the application root directory. To provide the necessary interface to manage deployment, we now create the __main__.py file with the following three lines of code.
if __name__ == "__main__":
from . import app
app.cli()
We can now test our application locally.
If you have not already, you must build your models before the application can be run. To build your models use the build command:
cd $HOME
python -m my_app build
Building application my_app...complete.
To launch the web service use the run command:
cd $HOME
python -m my_app run
Numerical parser running, PID 20248
Loading intent classifier: domain='store_info'
...
* Running on http://0.0.0.0:7150/ (Press CTRL+C to quit)
To test using any REST client (such as Postman or Advanced Rest Client), send POST requests to the web service endpoint at http://localhost:7150/parse. Alternately, you can use a curl command from your terminal as follows:
curl -X POST -H 'Content-Type: application/json' -d '{"text": "order from firetrail"}' "http://localhost:7150/parse" | python -m json.tool
Note
The MindMeld flask server is stateless, so in order to perform multi-turn dialogues with the server, copy the response returned from the server in the first turn and use that in the data parameter of the curl request in the next turn, along with the new text key, value.
