训练rasa时如何解决domain.yml中的错误

Question

While running rasa train , I get an error which automatially takes an empty domain.yml instead of the .yml file that I want to choose . The error shows that there is a presence of duplicate keys.

C:\\Users\\nitik\\rasabot>rasa train c:\\users\\nitik\\appdata\\local\\programs\\python\\python37\\lib\\site-packages\\rasa\\utils\\common.py:351: UserWarning: Loading domain from 'domain.yml' failed. Using empty domain.

How can I help you today ?" (original value: "Hello. I am a medicare locator. I can help you find nearest hospital. How can I help ?") in "", line 43, column 3

docs=DOCS_URL_DOMAINS, Your Rasa model is trained and saved at 'C:\\Users\\nitik\\rasabot\\models\\nlu-20200402-224056.tar.gz'. Core training was skipped because no valid domain file was found. Only an nlu-model was created.Please specify a valid domain using '--domain' argument or check if the provided domain file exists.

Answer 1

Your domain.yml is not a valid YAML file, so Rasa cannot use it and starts instead with an empty file.

Go to http://www.yamllint.com/ and paste the content of your domain.yml, you can easily validate it and find the error/inconsistency (sometimes it is just indentation, but it seems you have some duplication reading error trace).
