SEGV, seems missing trace files

[YangZhou1997]

Hi SimAI maintainer,

Excellent work! I am trying to run SimAI-Simulation, but hit SEGV errors, see below.

I guess the out-of-box repo miss some trace files, so I wonder where I can get them.

Best,
Yang

Well, the SEGV disappear after I sudo mkdir -p /etc/astra-sim/simulation/...

Btw, where I can get flow1.txt and trace1.txt? Thank you!

I assume you wish to trace the flow dynamics within ns3, like switch throughput, NIC throughput, and switch queue information, which would be easily visible in the newer ns-3-alibabcloud version.
