Bug in Dit that could affect Pixart

[Bigfield77]

Hello,

I am not sure if this is relevant: facebookresearch/DiT#41 (comment)

Basically a user asked a question about why classifier-free guidance was only applied to 3 dimension:

According to the reply the issue would also be present in Pixart.

I haven't checked due to my limited knowledge:)

cheers

Yah, we tried to change it from 3 to 4, which not influence much. And our default sampler is DPM-Solver, which don't have this bug issue.
