Confusion about Generator

[leesocool]

Thank you for your excellent work!
I have some questions about the Generator.

There are two implementation methods for upsampling in the code, "UpBlock" and "UpBlockComp", but the architecture in the paper does not mention the latter. I would like to ask when to use "UpBlock" and when to use "UpBlockComp"

and

Hope to get your response.
