I have ` social_dilemmas` folder and `rollout.py`, but I do not know why they cannot be recognized.

I suspect you skipped the step of running python setup.py develop?. It looks like the folders aren't in your pythonpath essentially.

Thanks for your reply!
I have fix this problem by
import sys
sys.append("..")

I have another error when running python -m pytest.

I cannot find `ray.rllib.utils`.

I fixed this error by pip install ray==0.6.1

Thanks for your reply!

sys.append("..")

were you added this pace if code? i am facing the same error while importing packages

@venkatasivaramireddy
You should not skip the step of running python setup.py develop. Before running rollout.py, we should run rollout.py firstly.
Otherwise, you can added:
import sys
sys.append("..")
at the beginning of rollout.py

My directory structure is like so
features
├── init.py
├── classes
----└── class_features.py (i have class ClassFeatures)
└── automation
---- └── test_features.py ( i need to import ClassFeatures into this file)
├── setup.py

In test_features.py, I am importing the class from class_features.py

from features.classes.class_features import ClassFeatures

but getting error,

from features.classes.class_features import ClassFeatures
E ModuleNotFoundError: No module named 'features'
