Error when using python textblob library tagger
<p>I had the textblob library working fine for a while, but decided to install (using easy_install) an additional library (<a href="http://stevenloria.com/tutorial-state-of-the-art-part-of-speech-tagging-in-textblob/" rel="nofollow">page here</a>) claiming faster and more accurate tagging.</p>

<p>I couldn't get it working so I uninstalled it, but it seems to have messed with the tagging function in TextBlob. I've uninstalled and reinstalled both nltk and TextBlob numerous times with both pip and easy_install, and made sure they're up to date. </p>

<p>Here is an example of a simple script which generates the error:</p>

<pre><code>from textblob import TextBlob

blob = TextBlob("This is a sentence")
print repr(blob.tags)
</code></pre>

<p>and the error printed:</p>

<pre><code>    Traceback (most recent call last):

</code></pre>

<p>You can see that the error actually mentions the perceptron tagger. Is there any way to more thoroughly remove any references there may be to the alternate tagger?</p>

<p>Also note that only the "tags" function has been affected.</p>
