Blend set to string

[muchogrande]

Hi, I can't seem to set -b to a string. Integers work fine, but 'loop' or 'blend' throw:

2_dreaming_time.py: error: argument -b/--blend: invalid float value: 'loop'

Tried without (as per instructions) and with quotations (single + double).

python 2_dreaming_time.py -i /Volumes/RAID_OSX/_SAKHEENA/_DD/_Sakheena_test_images -o /Volumes/RAID_OSX/_SAKHEENA/_DD/_output --model_path /usr/local/caffe/models/bvlc_googlenet/ --model_name bvlc_googlenet.caffemodel --gpu 0 -octs 1.3 -b loop -l inception_4e/3x3_reduce
