What user did you set for your ark-node database? If you followed these lines in the arkdbtools guide:

sudo -u postgres psql 
    psql=# ALTER USER <username> WITH ENCRYPTED PASSWORD '<password>'

then your credentials should be entered in the config.py

CONNECTION = {
    'HOST': 'localhost',
    'DATABASE': 'ark_mainnet',
    # The 2 lines below need to be edited if you created a user to query the ark-node
    'USER': 'ark',
    'PASSWORD': None,
}

Also it seems like you are using python 2.7. I am not sure if this works in that version. I personally use python 3.6.
For different projects I always suggest using virtual environments. Anaconda is a great tool for this, especially since you can create environments in different python versions: https://conda.io/docs/user-guide/install/index.html
