missing assets in the environment

[WeiChengTseng]

Hi! Thanks for sharing this cool project.

Recently, we would like to reproduce the results of this work, and I ran
python run.py --conf ../configs/cartpole/train/adap.yaml --exp-name cartpole

Then, I got the error shown below.

Traceback (most recent call last):
  File "run.py", line 5, in <module>

It seems that some assets are missing in this repo. Can you add those assets to the repo as well?

Thanks for bringing this to my attention, glad you are interested in the project! For now I have removed these missing dependencies - hopefully it runs, but I know that the underlying Rllib has also changed since I posted this code. By tonight I'll try to put up a more comprehensive fix, including the Farmworld dependencies so you can work on that env.

Thanks for the quick response, and I am looking forward to your further update 😄.

May I roughly know when the environment (Farmworld) will be included? I am looking forward to your updates. Thanks a lot.

Apologies for the delays, I expect one or two more days. If you want, there is code in the add_farm branch that should allow you to run things with Farmworld right now. The run.py script is slightly modified so it does not exactly coincide with the README.md, but you can just look at the code to see what cmd arguments need to be.

The main part I'm working on is getting a decent environment wrapper/interface that that allows you to adapt latent codes to fit ablations in an environment-agnostic(ish) manner - the code I was using before was very hacky into the environments themselves (so it didn't allow you to swap/experiment on your own envs). In the meantime, were you able to get it working with CartPole?

[WeiChengTseng]

Thanks for your effort in making the repo. complete. I am able to work with CartPole, and the results seem to be reasonable. Although the underlying Rllib has also changed, it seems that it doesn't cause any issue for your code 😄.
