extractors fail

I am having problem getting the extractors from the second README example to work. here is the code to recreate:

from pliers.stimuli import VideoStim
from pliers.extractors import (STFTAudioExtractor, PredefinedDictionaryExtractor, ComplexTextExtractor, ClarifaiAPIExtractor, IndicoAPITextExtractor)
from pliers.filters import FrameSamplingFilter
from pliers.graph import Graph
clips = ['../pliers/pliers/tests/data/video/obama_speech.mp4']
clips = [VideoStim(f) for f in clips]
#nodes=[PredefinedDictionaryExtractor(['subtlexusfrequency/Lg10WF'])]
nodes=[IndicoAPITextExtractor(models=['sentiment'])]
g = Graph(nodes)
result = g.run(clips)

using either of those nodes, I get an HTTPError: HTTP Error 401: Not Authorized. The earlier nodes in the example work fine so it’s not a general problem with my setup.

would you mind trying it out within the docker container using your credentials so that we can see whether it’s something specific to that environment?

Re: testing API failure, I think we should definitely add a utility function to test this more systematically. Will open a new issue for discussion.
