i found a bug when trying to update my model. for me sometimes my code worked and sometimes updating my model did not work and threw an error. i could not understand why, but now i found that when my tuning run finds differencing, then i can update without problems, if no differencing is applied, then updating throws an error. i have added a loom video where you can see me running the same code but in one case i use differencing order 1 and in the other order 0 (so no differencing) and when there is no differencing, updating fails: https://www.loom.com/share/b7bda858a2264e7e808d842bf1570e94?sid=e75f6ba5-9a59-470e-90a5-ca6456b98614

Hey. We don't support

d=0

in differences, the error you're seeing is coming from doing something like

np.arange(0, 10, 0)

. If you want to disable differencing please just set

target_transforms=None

ahh, ok. but i have never had a problem so vfar and always used [0,1] for differencing. only time i see the problem is now when trying to update. but thanks for your tip, i will try!!
