p4run problem

[zwllwz823]

Hey everyone,
I just used copy my p4app.json to the p4run folder and use these commands:
p4run
sudo p4run
sudo p4run --config p4app.json
But all of these commands gives me the feedback:

Traceback (most recent call last):
File "/usr/local/bin/p4run", line 11, in
load_entry_point('p4utils', 'console_scripts', 'p4run')()
File "/home/zwl/p4-utils/p4utils/p4run.py", line 736, in main

ModuleNotFoundError: No module named 'p4utils.mininetlib.p4net'

I tried many ways but no one works.
I even uninstall p4utils and install again in my VM but it still goes wrong.
can anyone help me please...

I believe its a problem with your installation and python installation.

Can you try import p4utils with python3?

@edgar-costa hello I also encountered this problem, can you explain it in detail? I am a student, thank you very much

Replenish:I installed it using the "install-p4-dev.sh" provided on this website. This picture is the situation I encountered. It is the same as this problem. I will encounter this problem when using all the sample programs on the Internet. , except the "examples" provided by p4utils itself can be executed, others cannot. Please help me solve this problem. I really need to use this to complete my studies. Thank you.

@a5539322 the problem you are showing in the screenshot has nothing to do with the thread.

Open a new issue. But in any case the problem is due to your code using the old version of p4-utils, p4net does not exist anymore. You will have to look at the new examples, there is plenty here: https://github.com/nsg-ethz/p4-learning/tree/master and translate your code so the imports work.

@edgar-costa Thank you very much for your help. Now I understand the situation I encountered. I will try to solve this problem again. Since I am only a student, I may have a poor understanding of many things. If I really can't solve it, I will ask again. Really Thank you very much for your help
