Follow the instructions to install the required libraries and tools which will be used during the workshop:

1. Install Python 3 (any version should work just fine, during the live demo Python 3.6.3 will be used).

   For people who are new to python, we recommend getting Python 3 with Anaconda https://www.anaconda.com/download/

2. Download or clone this repository. This repo contains a requirements.txt file which we will use to install the dependencies. Install the dependencies by executing:

   pip install -r requirements.txt

   Note: Requires C++ compilers. Make sure you got them on your machine or download and install them before installing dependencies from requirements.txt:

   • Visual Studio for Windows https://www.visualstudio.com/
   • XCode for macOS/OS X https://developer.apple.com/xcode/
   • gcc for Ubuntu https://gist.github.com/application2000/73fd6f4bf1be6600a2cf9f56315a2d91

   The installation should run without the errors. A successful installation should be indicated by a message that the list of dependencies was successfully installed:

3. Install spacy model by running:

   python -m spacy download en

   Note: If installation throws an error, run the terminal as an administrator and rerun the command.

   After the successful installation you should see a similar output in your console:

4. Install rasa_core by running:

   pip install rasa_core

   The installation should be completed without any errors and it should end with a message saying that the libraries were successfully installed.

5. Install apixu library:

   • Download or clone https://github.com/apixu/apixu-python
   • Unzip and execute:
     python setup.py install

   A successful installation should be indicated by a message similar to the following:

6. As a sanity check, at this step you can launch your python interpreter and import rasa_nlu, rasa_core, apixu, spacy libraries as well as spacy model. If it doesn't throw you any errors, it means that everything was installed successfully.

   In your console type the following:

   python (to launch the Python interpreter)
   import rasa_nlu
   import rasa_core
   import apixu
   import spacy
   nlp = spacy.load('en')

   If everything was installed successfully, you should see the following in your console:

7. Download and install npm and node from https://nodejs.org/en/download/

8. Install rasa_nlu data visualisation tool by executing:

   npm i -g rasa-nlu-trainer

   A successful installation should result in a similar message in your console:

If you want, during this workshop you can use an IDE of your choice or you can stick to simple text editors (for example Notepad++). Both options will be just fine.

If you have any questions or issues regarding the installation, feel free to message me directly or drop me an email to [email protected] and I will be glad to help you out :)
