This is python 3 issue. Please compile with Python 2.7 On Monday, June 3, 2019, 12:03:14 PM GMT+5:30, turtle-23 notifications@github.com wrote:

In my ubuntu system ,root has python 3 and I cant degrade the python version .So ,I am executing this file inside a virtual environment with python 2.7. But while running python file I got the error:

Traceback (most recent call last): File "deterministic_trial.py", line 7, in env = gym.make("Sdwan-v0") File "/home/ubuntu/my_env/local/lib/python2.7/site-packages/gym/envs/registration.py", line 156, in make return registry.make(id, kwargs) File "/home/ubuntu/my_env/local/lib/python2.7/site-packages/gym/envs/registration.py", line 101, in make env = spec.make(kwargs) File "/home/ubuntu/my_env/local/lib/python2.7/site-packages/gym/envs/registration.py", line 72, in make cls = load(self._entry_point) File "/home/ubuntu/my_env/local/lib/python2.7/site-packages/gym/envs/registration.py", line 17, in load mod = importlib.import_module(mod_name) File "/usr/lib/python2.7/importlib/init.py", line 37, in import_module import(name) File "/home/ubuntu/sdwan-gym/gym_sdwan/envs/init.py", line 3, in from gym_sdwan.envs.mininet_backend import MininetBackEnd File "/home/ubuntu/sdwan-gym/gym_sdwan/envs/mininet_backend.py", line 3, in from mininet.net import Mininet

Then I copied "mininet" folder inside /home/ubuntu/sdwan-gym/gym_sdwan/envs folder. But now this message is coming on screen:

I can't use sudo python deterministic_trial.py command to run the file as it will use python 3. Please guide me on the steps to project setup .

Thanks in advance :)

source your virtual env inside your .bashrc and then do a "sudo bash". Then run the python file.(Do not directly run with python file with sudo as you have figured it out already). Also clear the mininet by mn -c command after every trial as it will say 'configuration already exists'. On Tuesday, June 4, 2019, 2:14:48 PM GMT+5:30, turtle-23 notifications@github.com wrote:
