Rasa_nlu.data_router CancelledError when trying to create more than one model

Rasa Open Source

Hello, i’m trying to simply train a model from a custom UI that I made

When I click on the button I call the function /create_model on the back end that will call the /train on a custom docker image rasa_nlu_fr like this :

var project_name = "project_name"
var model_name = "model_name"

var options = {
    url: 'http://localhost:5000/train?project='+project_name+'&model='+model_name,
    method: 'POST',
    headers: { 'content-type': 'application/x-yml' },
    body: fs.readFileSync('./rasa/nlu_config.yml','utf8'),
    encoding: null
};

request(options, (error, response, body) => {

    if (!error && response.statusCode == 200) {
        console.log("ok!")
        resp.json({ "text": "model "+model_name+", on projet "+project_name+", created."})
    }
    else
        console.log("problem.")
});

I created a custom image of rasa_nlu to add french corpus like this :

FROM rasa/rasa_nlu:stable-full 
RUN pip install https://github.com/explosion/spacy-models/releases/download/fr_core_news_md-2.0.0/fr_core_news_md-2.0.0.tar.gz --no-cache-dir > /dev/null \
    && python -m spacy link fr_core_news_md fr 
VOLUME ["/app/projects", "/app/logs", "/app/data"]
EXPOSE 5000
ENTRYPOINT ["./entrypoint.sh"]
CMD ["start", "-c", "config.yml", "--path", "/app/projects"]

The problem is that when I click the button once it creates the model correctly no error no problem, but when I do it more than one I’m getting this:

I have stop the container completely with : sudo docker stop $(sudo docker ps -a -q) sudo docker rm $(sudo docker ps -a -q) sudo docker system prune
