VAE+NF

[limingzhan0904]

Thank you for your great work.
However, when I implement VAE + NF, my kld, q(zK||p(z)), tends to be lower than 0. I think if it is a problem caused by only sample one z_0 per data point(i.e. L=1 in the vae paper).
I have been confused by this problem for weeks, I appreciate your help.
