How can make ConvTranspose2d to upsample an image with 1.5 factor scale?

is it possible to apply 1.5 factor scale using ConvTranspose2d it doesn’t work with me for the two dimensions

loosely speaking, factor \approx stride, so you can’t make it upsample 1.5x.

do you think that there is any other way to use Deconv to upsample 1.5 and not any interpolation methods.
