How to Install Rasa Open Source

Rasa is an open-source machine learning framework for making chatbot based on automated text and voice-based conversations. Rasa understands messages, hold conversations, and connect to messaging channels and APIs.

 

Installation

In this blog, there are two methods of Installation are described  below:

 

A. Installation of Rasa Open Source using pip.
     
 1. Python Environment Setup
 
 Check first python3 and pip3 version by using below commands:
 
 -  python3 --version
 
 -  pip3 --version

 The above commands should display the version, and if Python 3.6, 3.7, or 3.8 and pip3 is already installed then you can skip the next step.

 

 For Ubuntu-

 Fetch the relevant packages using apt, and install virtualenv using pip.

 - sudo apt update
 - sudo apt install python3-dev python3-pip

 For macOS -

 Install the Homebrew package manager if you haven't already.
 Once you're done, you can install Python3.

 -  brew update
 -  brew install python

 For Windows -

 Make sure the Microsoft VC++ Compiler is installed, so python can compile any dependencies. You can get the compiler from Visual Studio.
 Download the installer and select VC++ Build tools in the list. Install Python 3 (64-bit version) for Windows.

 - pip3 install -U pip

2. Virtual Environment Setup

 

This step is optional, but this is strongly recommended to create python projects using virtual environments.

 

 For Ubuntu-

 Create a new virtual environment:

 - /usr/bin/python3.8 -m venv ./venv

 Activate the virtual environment:

 - source ./venv/bin/activate 

 For macOS -

 Create a new virtual environment:

 - /usr/bin/python3.8 -m venv ./venv

 Activate the virtual environment:

 - source ./venv/bin/activate 

 For Windows -
