Hello,
Currently getting the following error:

main()
File "./discogan/image_translation.py", line 131, in main
test_B = read_images( test_style_B, 'B', args.image_size )
File "/Users/haosun/Raju/DiscoGAN-master/discogan/dataset.py", line 53, in read_images
images = np.stack( images )
File "/Users/haosun/Raju/anaconda/lib/python3.6/site-packages/numpy/core/shape_base.py", line 350, in stack
raise ValueError('need at least one array to stack')
ValueError: need at least one array to stack

after downloading the dataset and running the following command:
python ./discogan/image_translation.py --task_name='edges2handbags'.

Please help to check.

Thanks
