Hello, @Aviais
Which version of pytorch did you use to get your model.pt file?
(To check the version:  python -c "import torch; print(torch.version.__version) )
Which version of gradle dependencies do you use?
It could be that the model was traced/scripted with different version from gradle dependencies, while between those versions aten::upsample_bilinear2d.out maybe changed.
If you trace/script with nightly build - its better to use android dependencies from nightly channel (https://github.com/pytorch/pytorch/tree/master/android#nightly)
And matching version of gradle dependencies and installed pytorch.
