Hi @1908639561 ,

I think your environment is not properly set. @yfle0707 Do you have clues about this?

Hi, @1908639561 , which SDE version you are using?

Also, could you please try commentating "import pltfm_pm_rpc" and try if we actually need that module?

Hi,@laochonlam @yfle0707 .Thank you so much for receiving your response! I am using SDE-8.9.1. but I am not using a real P4 physical switch, I installed SDE-8.9.1 on a server with ubuntu-16.04 because I wanted to do it on Tofino Model first. Also, when I run it after commenting out "import pltfm_pm_rpc", it has this problem:

When I commented out the sentences at the same time, it worked successfully.But I don't know why and what are the effects of doing so. https://github.com/in-ATP/ATP/blob/ddca27f035edcd970abdbbfef400045d79afd3fa/ptf/ptfTest.py#L4 https://github.com/in-ATP/ATP/blob/ddca27f035edcd970abdbbfef400045d79afd3fa/ptf/ptfTest.py#L11 https://github.com/in-ATP/ATP/blob/ddca27f035edcd970abdbbfef400045d79afd3fa/ptf/ptfTest.py#L56

Output after successful run：

Hi,

The variable self.platform_type is not used, thus, it does not impact on the current program.
