Wrong loss function in toy_demo

[dachylong]

Thanks for sharing the code, the idea for distributional discriminator is great. However, I find the following issue in the toy_demo notebook:

According to my understanding, in toy_demo.ipynb In [7], the labels parameters of D_loss_00, D_loss_01, D_loss_10, D_loss_11 & G_loss_01 should be wrong.

Point me out if I am wrong.
