cannot send gtpu uplink and downlink

[hahada5]

Hi, thanks for sharing.

Nowadays I wanna try this project but face the problem us that I couldn't send gtpu uplink or downlink with code util/mn-cmd h1a python /mininet/send_gtp_uplink.py.

I have set the environment and also created PDU session.

Could you give me some advice about it?

BTW, the log of failure is "cannot find python" which looks like python problem, but I tried python /mininet/send_gtp_uplink.py directly in the file, log shows that it sent 5 packet but cannot configure internet(of course this log shows), just wanna say the file works well actually.

Thanks for your help in advance.
