yellowbrick visualiser.fit() raises ValueError

I am trying you Visualise a dispersion plot for my twitter data

Here is the link to the datset

dataset

This is the code 

from yellowbrick.text import DispersionPlot

text = combine['tweet']
target_words = ht_negative_unnest

visualizer = DispersionPlot(target_words)

visualizer.poof()

I'm trying to pass a list like this in the above code stored in ht_negative_unnest

I think wso isn't found in your corpus; only #wso.

Have you tried a single target word like ['love']? Do you still get the error?
