Hi, @owang @sridharmahadevan @akanimax @huangzh13

I have met this error when run train.py ...
What's wrong to me?

oem@sgi:~/BMSG-GAN/sourcecode$ python3 train.py --depth=7 --latent_size=128 --images_dir='../data/celebJapan/train' --sample_dir=samples/exp_2 --model_dir=models/exp_2
Total number of images in the dataset: 6604

error message -

TypeError: mul() received an invalid combination of arguments - got (numpy.float32), but expected one of:

Thanks in advance ~
