@xyang16 Any idea why bumping pytorch is causing the Onnx Runtime build to fail with

java.io.FileNotFoundException: https://publish.djl.ai/pytorch/2.7.0/jnilib/0.34.0/linux-x86_64/cpu/libdjl_torch.so

?

@qthequartermasterman Thanks for contributing! Could you update to pytorch 2.7.1? Looks like 2.7.1 is the latest stable release.

@xyang16 Happy to make this change, but I am making this change in anticipation of deepjavalibrary/djl-serving#2841. vLLM==0.9.1 requires exactly torch==2.7.0. Would it be acceptable to build both versions? Or would building 2.7.1 be fine?

@xyang16 Is there any update on this?
