Reg- unable to run code

[jaswanthiiit]

Hi ,

I am trying to run your code through jupyter notebook connecting from anaconda prompt by the method you described earlier like unzipping etc. getting few issues like:

once i open the simulator app, I get following exception found at end in log file. I cannot file .cs file. please help me in this regard.

Can you please suggest me step by step procedure to execute as i am beginer to RL concepts... Thank you.

Could you tell me the code execution process for each ipynb files in RL algorithms folder.

@jaswanthiiit Sorry for late reply. I went to military training for a month, so I couldn't use any electronic devices. I moved unityagents folder into the RL_algorithms folder. I think it will fix the issue. I will tell you how to execute this project.

1. download the github repo
2. download the simulator and put all the files into the environment folder
3. open the ipynb file in the RL_algorithm folder and run it!

Thank you.

I have resolved the problem when I modified a line of code：

from RL_algorithms.unityagents.environment import UnityEnvironment

[JunaidRana]

have resolved this using this command.

from mlagents.envs import UnityEnvironment
