"TypeError" exception when a song is not recognized #1

Closed pguridi closed 10 years ago

pguridi commented 10 years ago

when checking a song and there is no positive match, using: .. recognizer = Recognizer(dejavu.fingerprinter, config) res = recognizer.read("14622976.wav")

throws the following exception, would be nice if a "NotFound" exception is throwed instead. *EDIT: or return None.

Traceback (most recent call last):
