• Fork this repo
• Clone it

https://github.com/Polaris000/BlogCode.git

• Create an environment with the required packages installed. (More info below)
• Navigate to a project
• Check the README inside each project for information specific to it.

• Creating an environment is straightforward. Though there are a few ways to do it,conda is a reliable way to go about it. Install conda fromhere.

• To create an environment run:

  $ conda create --name <env_name> python=3.8.10

• After the setup is complete, activate the env.

  $ conda activate <env_name>

• The packages required to run these code samples are mainly of two kinds:

  • Rasa dependencies
  • Python data visualization and machine learning libraries

• If you want to install both, userequirements/requirements.txt in your env

  (env)$ pip install -r requirements/requirements.txt

• If you want to install rasa dependencies, userequirements/rasa_requirements.txt in your env

  (env)$ pip install -r requirements/rasa_requirements.txt

• If you want to install python machine learning dependencies only, userequirements/non_rasa_requirements.txt in your env

  (env)$ pip install -r requirements/non_rasa_requirements.txt

• If you're interested in usingRasa X for a more visual experience while improving and conversing with your bot, you'll require these additional steps:
  • Downgrade pip to fix a circular dependency issue

    $ pip install pip==20.2

  • Install rasa x

    $ pip install install rasa-x==0.38.1 --extra-index-url https://pypi.rasa.com/simple
