gym.error.UnregisteredEnv: No registered env with id: merge-multi-agent-v0 about marl_cavs

[DongChen06]

Hi, Kumuda, thanks for your interest. Could you please check whether this file exists?

Or you can add the following code in the run_mappo.py.

import sys
sys.path.append("../highway-env")

Thank you for your reply @Derekabc . Please note, this error occurs when I try to run he run_mappo.py from terminal. And both of your suggestions are implemented but still the error appears.

Also when I execute the run_mappo.py using run options (highlighted in white marker) :

I get the error: "/Users/suhas/venv/bin/python: can't find 'main' module in '/Users/suhas/opt/anaconda3/envs/marl_cav/lib/python3.6'"

You can see the error too in the screenshot provided.

@KumudaBG Could you reach me out via email and we can have a quick chat to find the issues if you want

Hi @Derekabc ,

I have almost the same problem. I have the below error while running the program in a server within a virtualenv created by conda,the version of python is 3.7.
I wonder if I got the right version of gym?

@KumudaBG @qiangyuchuan I just tested the code on a new Ubuntu20.04 machine, it seems it can run successfully without any issues. I made some small changes to the code, thus we do not need to make any directories as the source directory. The main steps are:

1. download the code.
2. create the environment and install the libs
3. click run_xx.py

The issues may come from the different platforms. Following is the libs I have:

Hi Dong, Thanks for letting me know the response in Ubuntu. I was able to fix the unregisteredEnv error after placing the below lines of code on top of the run_mappo.py file. import sys sys.path.append("/Users/suhas/Desktop/SJSU/SEM4/CMPE260/MARL_CAVs/highway-env") But getting this error. [image: Screen Shot 2021-11-03 at 11.51.37 AM.png] Because I don't have any models in the results/models folder. Could you please help me with this? Regards, Kumuda

@KumudaBG It seems the image is broken and I cannot see it.

@KumudaBG It seems the image is broken and I cannot see it.

Here is the error @Derekabc

[DongChen06]

@KumudaBG actually, it's not an error and just tells you that there is no pretrained model to load. You will see the evaluation videos soon.

[kumudamurthy]

@Derekabc will wait for it and let you know, thank you.
After the evaluation, will there be a model saved in that folder?

[DongChen06]

@Derekabc will wait for it and let you know, thank you. After the evaluation, will there be a model saved in that folder?
