How to set parameters for ONLY HORIZONTAL dataset?

[kizoooh]

@dbolya Thank you for you great project! So I want to train it on my own dataset, and it's full horizontal. You can imagine it like a row of cylinders, I can get masks of those short ones, but I cannot mask those long ones.

Some friends said that I should change "aspect_ratio" and "aspect_scales"

So how should I do to my parameters to fit this?
