6dof-augmentation didn't work

[sean6585]

when I ran the debug.py file using following command:
python debug.py --phi 0 --annotations linemod SSD/ --object-id 1
the error show up like this

and I found that the problem is in this line shown below, the output is empty(annotations = [ ]).

Once I disable the 6dof-augmentation option, my annotation result can be visualized.

And another problem is why my 6d-pose bbox is always rotated 90 degrees ?
