RuntimeError: could not create an engine

从 oneCCL Bindings for PyTorch Getting Started Sample 以及第 26 行和第 67 行报告的 demo.py 入口点开始，然后使用带有 -dev xpu 的 mpirun -n 2 重现该命令。检查 issue 中列出的 PyTorch 和 Intel Extension for PyTorch 版本；完成标准是确定 engine 创建的原因，并确认 sample 在所述 PVC 配置上成功运行。

Hi Intel Team

I am observing "could not create an engine" error in executing demo.py example from "oneCCL Bindings for PyTorch Getting Started Sample*". The code is run on Saphire node with 4 PVCs at TACC system. Any suggestions on identifying the cause and fixing it?
