Annotations nan

There are several annotations that are NaN

Check a snippet that shows some samples that are Nan in the world set

>>> from bob.db.meds.database import Database
>>> db = Database(protocol="verification_fold1", original_directory="")
>>> samples = [[i, x.key,x.annotations] for i,x in enumerate(db.background_model_samples())]
>>> print(samples[119])
[119, './data/ab/S200-01-t10_01.jpg', {'leye': (nan, nan), 'reye': (nan, nan)}]
>>> # Prining all samples that has Nan annotations
>>> print([[s[0],s[1]] for s in samples if numpy.isnan(s[2]['leye'][0])])
[[82, './data/ab/S131-01-t10_01.jpg'], [112, './data/ab/S180-01-t10_01.jpg'], [119, './data/ab/S200-01-t10_01.jpg'], [139, './data/ac/S237-01-t10_01.jpg'], [144, './data/ac/S245-01-t10_01.jpg'], [170, './data/ac/S290-01-t10_01.jpg'], [207, './data/ad/S362-01-t10_01.jpg']]

Do you have some time to look into that?

This invalidates all the experiments we've done so far :-(

Thanks
