Add Twins to SMP

[melikechan]

Sorry for not being descriptive but it would be benefical to add this transformer-based model to SMP. I will add a more quality description ASAP

Hey @melikechan, twins encoder is supported, see https://smp.readthedocs.io/en/latest/encoders_timm.html (at the very bottom of the page)

You can use it as follows

model = smp.Unet("tu-twins_pcpvt_base")

Please use tu- prefix for any encoder from timm library

I was actually asking about the model itself, instead of using its encoder in another model.
