Summarise your Spark chatroom conversations into visual wordclouds separated into key topics:

1. Install python package for virtual environments

pip install virtualenv

2. Start a virtual environment:

virtualenv -p python3 venv

3. Activate virtual environment:

source venv/bin/activate

You are now working within the virtual environment

4. Install packages to the virtual environment:

pip install flask Pillow wordcloud nltk numpy scipy sklearn requests

For nltk, you also need to run dependencies.py to download the models.

5. Once everything is installed, cd into webserver and:

source credentials.sh

6. Then just run python recap_v1.2.py from terminal and access the page through localhost:8080 in your browser. Sign in to your Spark account and get started!

• to fix an error with python not installed as a backend on OS X go cd ./venv/lib/python3.5/site-packages/matplotlib/mpl-data/ inside the virtual environment and add backend: TkAgg to the "matplotlib.rc" file
