I cannot find out p4net and Topology about p4-utils HOT 2 CLOSED

Hi!

I believe this is because we did a big update to the entire codebase some months ago and several things are not backwards compatible.

For example to load the topology you can use:
https://github.com/nsg-ethz/p4-learning/blob/master/exercises/08-Simple_Routing/thrift/solution/routing-controller.py#L8

If you check the helper, right now the topology object is called different.

https://github.com/nsg-ethz/p4-utils/blob/master/p4utils/utils/helper.py#L279 NetworkGraph

Looks like that github you sent me is using the old version of p4-utils.

https://github.com/nsg-ethz/p4-utils/releases/tag/v0.0 Here you can find the old version. But be careful, it will only work if python is python2.

Otherwise you can check what are the differences, now everything is way more documented. You will only have to change some small things in the controller and maybe p4app.json but it will be minimal.(and use the new vm). For reference, check all the exercises in p4-learning

from p4-utils.

Oh, Thanks for your useful help.
It works well after I follow your advice.
And I am looking at p4-learning which is a good course. Wonderful !
