nltk wordnet concurrency error WordNetError

[ndvbd]

When running wordnet in multiple threads I get strange errors.
I am trying to get the synsets of a word.
Is Wordnet thread safe? Is there a way to solve it? If there is not immediate solution, where is the database of all words and their functions (verb/adjective/noun) stored?

The exceptions look like this:

raise WordNetError('line %r: %s' % (data_file_line, e))
  File "/usr/local/lib/python2.7/dist-packages/nltk/corpus/reader/wordnet.py", line 1342, in synset_from_pos_and_offs
et
    assert synset._offset == offset

I have this same issue. I'll report back if I find a solution.

Any solution to this issue?

I gave up and just waited for it.

Sorry this code is not threadsafe.
