Inception score for conditional GANs

[Defa Zhu]

IMO，there are tow ways to calculate Inception score of conditional GANs.

1. For every "condition", calculate a IS and Average them.
2. Sample "condition" from "real condition distribution" and generate fake data to calculate IS.
   Which way is reasonable.
   thx.

I also has this problem, I don't undersdand the detail of the calculation of Inception score perfectly.
