Building a chatbot with Rasa NLU and Rasa Core

[@gilsondelrei9955]

This is a kind of video that deserve an update using latest version and many applauses.

[@prabhatdreamz]

Excellent tutorial. Even a dunce like me could follow it. Thank you for the simple yet very effective video.

[@akshaybarge3217]

not many tutorials available on the internet for rasa. Great content from you. Subbed !! I feel one advantage of rasa over dialog flow is that in dialog flow even the basic feature of textual responses is limited to 180 requests per minute even in free edition. In rasa it seems to be free and unlimited.

[@carlossegura403]

Amazing!! And your accent made it easy to follow. 👌

Thank you so much for making video on Rasa .

Thanks for this wonderful tutorial....will wait for more such videos from your channel...

[@SandeepKumar-nr9kg]

I created a few intents (100 odd examples in data.json file ) with no entities and 15+ actions by following through this tutorial. But when i train the rasa nlu model and run the same for some samples i noticed that the model predictions are not correct for every test case. Can you tell me why the model rankings are not as expected?

Is there a command for online training (like at 1:03:00) with Rasa 2?

This video is two years old you don’t need the requirements file anymore, even if you do use the file all of the versions listed are also two years old so they wouldn’t work with whatever you are running.. install rasa on a virtual environment and all of the dependencies are included except for spacy npm and nodejs you have to install those separately.. Also what she refers to as rasa nlu trainer in the video is now called Rasa X and that needs to be installed separately as well.. I’m running python 3.6 on Ubuntu 18.04 and it works fine for me..

How can I integrate this console base chatbot to my website??

[@jpboost8077]

One of the approaches which you can try is running Rasa agent as an http server and connect it to your website's UI using http requests. Another way to do this is to create a webhook which you could use to emulate Rasa agent by making http requests. You can find more details about that on Rasa docs rasa.com/docs/core/connectors/#custom-channels. I will do a tutorial on that at some point.
