DRL_based_SelfDrivingCarControl Reg- unable to run code

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:

ModuleNotFoundError Traceback (most recent call last) in () 8 import time 9 ---> 10 from unityagents import UnityEnvironment 11 12 get_ipython().run_line_magic('matplotlib', 'inline')

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.
