Hi, I have created a chatbot on slack using Rasa-Core and Rasa-NLU by watching this video : Building a chatbot with Rasa NLU and Rasa Core on Vimeo It works pretty well on Slack.com . But what I need is to add this to our website using a code snippet. When I looked up on that, I was able to find out that RASA Webchat ( GitHub - mrbot-ai/rasa-webchat: A simple webchat widget to connect with a chatbot ) can be used to add the chatbot to the website. So, I pasted this code on my website inside the < body > tag. <div id="webchat"/> <script src="https://storage.googleapis.com/mrbot-cdn/webchat-0.4.1.js"></script> <script> WebChat.default.init({ selector: "#webchat", initPayload: "/get_started", interval: 1000, // 1000 ms between each message customData: {"userId": "123"}, // arbitrary custom data. Stay minimal as this will be added to the socket socketUrl: "http://localhost:5500", socketPath: "/socket.io/", title: "Title", subtitle: "Subtitle", profileAvatar: "http://to.avat.ar", }) </script> “Run_app.py” is the file which starts the chatbot ( It’s available in the video : Building a chatbot with Rasa NLU and Rasa Core on Vimeo ) Here is the code of Run_app.py : from rasa_core.channels import HttpInputChannel from rasa_core.agent import Agent from rasa_core.interpreter import RasaNLUInterpreter from rasa_slack_connector import SlackInput nlu_interpreter = RasaNLUInterpreter('./models/nlu/default/weathernlu') agent = Agent.load('./models/dialogue', interpreter = nlu_interpreter) input_channel = SlackInput('xoxp-381510545829-382263177798-381274424643-a3b461a2ffe4a595e35795e1f98492c9', #app verification token 'xoxb-381510545829-381150752228-kNSPU0X7HpaS8oJaqd77TPQE', # bot verification token 'B709JgyLSSyKoodEDwOiJzic', # slack verification token True) agent.handle_channel(HttpInputChannel(5004, '/', input_channel)) I want to connect this python chat-bot to the “Rasa-webchat” instead of using Slack. But I don’t know how to do that. I tried looking everywhere, But I couldn’t find anything helpful on the internet. Can someone help me? Thank you.

Hi Dilanka, you need two things: You need to setup a socket channel as described here: Socket.io Channel Setup In the widget snippet, you need to add your socketUrl and socketPath OT: I found myself in a similar situation a few weeks ago. Depending on your use case, instead of using the Rasa webchat widget, it could be useful to setup a Messenger bot and just use the Facebook chat widget snippet on your website as well. For me, as I wanted a Messenger bot with all its features (e.g. button types), this was the easier way to do it.

Thank you Simon, I just changed the ,py file like this : from rasa_core.channels import HttpInputChannel from rasa_core.agent import Agent from rasa_core.interpreter import RasaNLUInterpreter from rasa_slack_connector import SlackInput from rasa_core.channels.socketio import SocketIOInput from rasa_core.agent import Agent from rasa_core.interpreter import RegexInterpreter nlu_interpreter = RasaNLUInterpreter('./models/nlu/default/weathernlu') agent = Agent.load('./models/dialogue', interpreter = nlu_interpreter) input_channel = SocketIOInput(user_message_evt="user_uttered", bot_message_evt="bot_uttered", namespace=None) # set serve_forever=False if you want to keep the server running s = agent.handle_channels([input_channel], 5004, serve_forever=False) I’m getting this error now : (base) C:\Users\Dilanka's laptop\Desktop\Chatbot\bot>run_app.py Traceback (most recent call last): File "C:\Users\Dilanka's laptop\Desktop\Chatbot\bot\run_app.py", line 6, in <module> from rasa_core.channels.socketio import SocketIOInput ModuleNotFoundError: No module named 'rasa_core.channels.socketio'

That looks weird. Can you share your rasa_core version? Quick idea: Can you try importing it like this: from rasa_core.channels import SocketIOInput

Still I’m getting this error : (base) C:\Users\Dilanka's laptop\Desktop\Chatbot\bot>run_app.py Traceback (most recent call last): File "C:\Users\Dilanka's laptop\Desktop\Chatbot\bot\run_app.py", line 6, in <module> from rasa_core.channels import SocketIOInput ImportError: cannot import name 'SocketIOInput' Can you please tell me how to check the rasa core version?

Strange, I just tested the same on my machine and it works as expected. In your python shell you can just type: import rasa_core rasa_core.__version__ In the same shell, can you then also try to import the socketio input: from rasa_core.channels.socketio import SocketIOInput Does it throw an error there as well?

I’m getting this error on both Anaconda prompt and windows CMD. (base) C:\Users\Dilanka's laptop>import rasa_core 'import' is not recognized as an internal or external command, operable program or batch file. (base) C:\Users\Dilanka's laptop>rasa_core.__version__ 'rasa_core.__version__' is not recognized as an internal or external command, operable program or batch file. (base) C:\Users\Dilanka's laptop>from rasa_core.channels.socketio import SocketIOInput 'from' is not recognized as an internal or external command, operable program or batch file.

Hi Dilanka, sorry for the late reply. You need to enter a Python shell, e.g. by just typing python in your CMD. Then you can try importing rasa_core.

Hi Dilanka , Did you get a solution for this. I am also stuck in the same scenario.

I am not sure the above error got resolved or not. I believe you have tried the demo Weatherbot based from the Video using Slack. If we want to switch to Socket IO - we have to first socket io then try compiling run_app.py. More details: if you look at the error, it says from rasa_core.channels import SocketIOInput ImportError: cannot import name ‘SocketIOInput’ You can check your installed location of rasa_core and it doesnt have socket.io.py. I did faced the issue and after importing I am able to execute run_app.py. Now I got stuck in receiving messages from front end app (react or javascript app). I am getting the message in the Bot server “405 error” (Method not allowed). Any Help is highly appreciated.
