Possible typo in IGNORE_HASH_KEYS

Hi,

The tuple IGNORE_HASH_KEYS in prodigy.util is as follows

('score', 'rank', 'model', 'source', 'pattern', 'pirority', 'path', '_view_id', '_session_id', 'answer')

Is the 6th term meant to be 'priority'?

Thanks! This was definitely a typo – already fixed it for the next release. Luckily, this key isn't really used by Prodigy anymore so it shouldn't have affected anything.
