First of all I strongly suggest you to create a virtual environment:
virtualenv env
source env/bin/activate
Install the requirements (Be aware to have the virtualenv activated):
pip install -r requirements
To have authenticated access to the API you need to create a custom TOKEN. Of course the production TOKEN must be secret! You can create a personal TOKEN in your Preferences under the voice API Authentication Tokens.
You need to copy the file secret.example with a new name secret. Change inside this file the voice TOKEN with your token.
cp secret.example secret
vim secret
After the installation run on your terminal:
jupyter notebook
And here we go!
