ImportError: cannot import name 'Visualizer' from 'gqcnn'

Hi, Thanks for your great job.

When I try to run tools/generate_gqcnn_dataset.py, got the following error:

Traceback (most recent call last):
File "tools/generate_gqcnn_dataset.py", line 59, in
from gqcnn import Visualizer as vis2d
ImportError: cannot import name 'Visualizer' from 'gqcnn' (/home/adminis/anaconda3/envs/gqcnn/lib/python3.7/site-packages/gqcnn/init.py)

Any help will be appreciate.

Try out this fix from #50, there are some other things going wrong with this script.
