Can't get attribute 'ImageList' on <module 'fastai.vision.data'

Part 1 (2019)

I know there is a similar question here about ImageItemList, but I seem to be having a reverse problem.

I trained my model on fastai 1.0.60 / torch 1.3.1 / torchvision 0.4.2 on one machine.
I’m trying to use that model for inference on a different machine - with the exact same versions of fastai / torch / torchvision.

Here’s the error I’m getting:

Any help pls?:slight_smile:
