WordNetCorpusReader error

[David Liontooth]

I installed the NLTK 3.0.0 release with python2.7.8.11 on Debian. My script bugs out with

   'WordNetCorpusReader' object has no attribute '_LazyCorpusLoader__args'

Here's the whole message:

Exception in thread Thread-4:

    args, kwargs  = self.__args, self.__kwargs
AttributeError: 'WordNetCorpusReader' object has no attribute '_LazyCorpusLoader__args'

Any suggestions as to what's going wrong?

Cheers,

Dave,

I just answered a similar question on stackoverflow. This error occurs when you access a LazyCorpusLoader proxy object for a second time while it is in the process of being converted into a WordNetCorpusReader object. This would take place if you were using `threading` or `multiprocessing`. In order to avoid this issue, be sure the LazyCorpusLoader has finished transforming into a WordNetCorpusReader object before accessing the LazyCorpusLoader proxy object for a second time. See my answer on stackoverflow for further information. (Your question doesn't provide much detail, so I can't address your particular situtation here.)

Cheers,

Justin
