Hello sir,

I installed sflow-rt by referencing "https://blog.sflow.com/2018/10/ryu-measurement-based-control.html#comment-form" link.

I started the sflow-rt on one tab and on another tab, i tried to create the mininet topology by using "sudo mn --custom sflow-rt/extras/sflow.py --link tc,bw=10 --topo tree,depth=2,fanout=2 --controller remote" command. While doing this, i faced "ImportError: No module named requests" error. I installed requests module but i am facing the same error constantly. Currently, i am using Ubuntu 18.04 and python 3.8.10.

Can you please help?

Best Regards,

Peter Phaal

Did you install the Python3 version of requests, e.g.

sudo apt-get install python3-pip

pip3 install requests

Try the latest version of sFlow-RT. The sflow.py script removes the dependency on the requests module.
