Error Initializing Talon

[chipallen2]

I installed talon using PIP on python 2.7. I'm trying to run the example but I get an error as soon as talon.init() is called. I can't figure out what parser it is colliding with - any ideas what is wrong? I didn't receive any error installing talon with pip.

Here's the code, error, and the other files I see on my system called parser.py.

Parser.py files:

vagrant@vagrant-ubuntu-trusty-64:/$ sudo find . -name "parser.py"
./usr/lib/python3.4/html/parser.py
./usr/lib/python3.4/email/parser.py
./usr/lib/python2.7/email/parser.py
./usr/lib/python2.7/dist-packages/jinja2/parser.py
./usr/lib/python2.7/dist-packages/yaml/parser.py
./usr/lib/python2.7/dist-packages/dateutil/parser.py
./usr/lib/python3/dist-packages/ufw/parser.py
./usr/local/lib/python2.7/dist-packages/cssselect/parser.py

Code:

import talon
from talon import quotations

talon.init()

text =  """Reply

-----Original Message-----

Quote"""

reply = quotations.extract_from(text, 'text/plain')
reply = quotations.extract_from_plain(text)
Print(reply)

Error

I think I found the culprit for anyone else having this trouble. I had installed a few of the packages using PIP instead of using ubuntu's apt-get. So when I re-installed lxml like this it started working.

sudo apt-get install -y python-lxml
