Couldn't launch the jeju_camp environment.

[Zhousiyuhit]

Hello, I encountered some problems that "couldn't launch the jeju_camp environment."

Maybe you can tell me how to solve this problem? Thanks~

You should write the path of environment to env_name. In my case, environment path is ../environment/jeju_camp so I wrote the above path to env_name

[Zhousiyuhit]

Sorry, I don’s know the environment path is python path? Or Unity path? Siyu Zhou ————————————————————————— Reinforcement Learning | Motion Planning Harbin Institute of Technology School of Astronautics Phone: 86+18845027614 Email: hitaezsy@gmail.com | 17s118203@stu.hit.edu.cn

Maybe I know it, it’s Unity path~ Siyu Zhou ————————————————————————— Reinforcement Learning | Motion Planning Harbin Institute of Technology School of Astronautics Phone: 86+18845027614 Email: hitaezsy@gmail.com | 17s118203@stu.hit.edu.cn

Yeah~ you should unzip the environment file to certain path, and write the path of the file to env_path :)

[Zhousiyuhit]

Thanks very much, I have another question about the environment path~ I installed Unity on macOs, so how to find the unity environment to launch?

Oh! Actually, you don't need Unity to launch the environment file. Just unzip it into some folder and set the env_path and just launch the ipynb file. However, I didn't update environment for Mac and Linux. I will upload them today!

[Zhousiyuhit]

Ok, thanks~😁 Siyu Zhou ————————————————————————— Reinforcement Learning | Motion Planning Harbin Institute of Technology School of Astronautics Phone: 86+18845027614 Email: hitaezsy@gmail.com | 17s118203@stu.hit.edu.cn

I just reset the environment path, and there was another NameError that “name ‘UnityEnvironment’ is not defined.” So if you update environment for Mac and the problem can be solved?

I updated it! :) Unzip the environment zip file into environment folder. And then run the ipynb file.

[Zhousiyuhit]

Ok, thanks a lot, I will try it now~ Siyu Zhou ————————————————————————— Reinforcement Learning | Motion Planning Harbin Institute of Technology School of Astronautics Phone: 86+18845027614 Email: hitaezsy@gmail.com | 17s118203@stu.hit.edu.cn

Oh, I succeed in importing the environment model, but the model is the 3Dball when I learned examples for Unity, so how can I get the "self driving car” model?

Really? It's odd.. Did you set env_path as ../environment/jeju_camp?

[Zhousiyuhit]

Oh, I just set the env_name like this:

env_name = "/Users/siyuchou/Desktop/DRL_Lab/DRL_based_SelfDrivingCarControl/SiyuZhou_3Dball”

But I think the environment zip file as you said is the safe-car model? It’s right?

Yes. The link of the environment.zip file is in the readme.md. Download it and unzip it! :)

[Zhousiyuhit]

Oh, the problem continued! env_name = "/Users/siyuchou/Desktop/DRL_Lab/DRL_based_SelfDrivingCarControl/environment/Contents/MacOS/jeju_camp" # Name of the Unity environment binary to launch train_mode = True # Whether to run the environment in training or inference mode It’s right?

And I run the jupyter notebook, the error can be shown as:

---

UnityEnvironmentException Traceback (most recent call last)

in () ----> 1 env = UnityEnvironment(file_name=env_name) 2 3 # Examine environment parameters 4 print(str(env)) 5 ~/Desktop/DRL_Lab/DRL_based_SelfDrivingCarControl/unityagents/environment.py in __init__(self, file_name, worker_id, base_port, curriculum, seed) 92 raise UnityEnvironmentException("Couldn't launch the {0} environment.

Oh. Okay. I uploaded my github version to 0.8! Please erase the previous version and download new version. And there will be environment folder. Unzip the environment_mac.zip into the environment folder. Then run the ipynb file. I think this can solve your problem! :smile:
