I'm attempting a 2D transformation using the nudged package.

The code is really simple:

I was able to figure out your issue. It is simply that nudge has somewhat problematic notation, which is poorly documented.

The estimate function accepts a list of coordinate pairs. You effectively have to transpose dom and ran to get this to work. I suggest either switching to numpy arrays, or using list(map(list, zip(...))) to do the transpose.

The Transform.transfom method is extremely restrictive, and requires that the inner pairs be of type list. Not tuple, not any other sequence, but specifically list. Your attempt to call trans.transform((x, y)) only happened to work by pure luck. transform assessed that the first element is not a list, and attempted to transform (x, y) as a pair of integers. Luckily for you, numpy operators are vectorized, so you can process an entire array as a single unit.

Here is a working version of your code that generates the correct plots using mostly python:
