PCI-SIG PCIe Lane Margin tool execution problem on Linux platform

[Johnny-CC]

Hi,

Sorry I'm not sure which location is correct. Just post here first.

I downloaded the Lane Margin tool from PCI-SIG (https://members.pcisig.com/wg/PCI-SIG/document/16429)  and I believe that this tool is provided by Intel.

and follow the "685662 PCIe-LMT-Gen4_Gen5-r0p77.pdf"
the scan process can be executed but it ended with below log.

---------------------------------------------------------------------
Linux OS

below is content of sc_test.py
I also tried to paste in python terminal but get the same result

====================================================

My Ubuntu version is 24.04.1 LTS
default python3 version is 3.12.3
I have followed the introduction guide on internet using pyenv to change my python3 version to 3.8.10

Need your help to check my error log and give more information to debug my environment's problem.

Thanks
