Crashed when loading a layer #7

Closed ququuy closed 4 months ago

ququuy commented 4 months ago

I encountered a crash in Unreal Engine while attempting to load a linear layer using the Atum Neural Network. I followed the instructions provided in the YouTube videos linked in the readme. Has anyone successfully completed this process and could offer some assistance?

Here's my crash report:

I'm using UE 5.2 and LibTorch 2.3.0 CPU

P1ayer-1 commented 4 months ago

LibTorch 2.3.0 is currently not supported. There is an issue with the offical Windows distrubition for LibTorch 2.3.0. The issue is reported here: https://github.com/pytorch/pytorch/issues/125013.

You can use LibTorch 2.2.1, which can be found in the latest release of this plugin or implement the bypass suggested in the PyTorch issue.
