运行jar包报错：ai.djl.engine.EngineException: Failed to load PyTorch native library

[Black200000]

命令：java -Dfile.encoding=UTF-8 -jar test.jar，服务器环境：麒麟操作系统，arm架构，不联网。

将ai.djl调用Pytorch模型的程序打成jar包运行，报错信息如下，求解答！程序未打包前可在 windows11的IDEA环境中正常调试运行

You need network access.

DJL by default download PyTorch native library at runtime. You need package offline distribution jar file to support offline deployment.

See: https://github.com/deepjavalibrary/djl-demo/tree/master/development/fatjar

Thank you！I will learn this example first
