Thus, the goal of our agent is to collect as many yellow bananas (healthy) as possible while avoiding blue bananas (rotten).\n\nThe state space has 37 dimensions and contains the agent's velocity, along with a ray-based perception of objects around the agent's forward direction.  Given this information, the agent has to learn how to best select actions.  Four discrete actions are available, corresponding to:\n\n- **`0`** - move forward.\n- **`1`** - move backward.\n- **`2`** - turn left.\n- **`3`** - turn right.\n\nThe task is episodic, and to solve the environment, our agent must get an average score of +13 over 100 consecutive episodes.\n\n## Getting started\n\n1. Download the environment from one of the links below.  You need only select the environment that matches your operating system:\n    - Linux: [click here](https://s3-us-west-1.amazonaws.com/udacity-drlnd/P1/Banana/Banana_Linux.zip)\n    - Mac OSX: [click here](https://s3-us-west-1.amazonaws.com/udacity-drlnd/P1/Banana/Banana.app.zip)\n    - Windows (32-bit): [click here](https://s3-us-west-1.amazonaws.com/udacity-drlnd/P1/Banana/Banana_Windows_x86.zip)\n    - Windows (64-bit): [click here](https://s3-us-west-1.amazonaws.com/udacity-drlnd/P1/Banana/Banana_Windows_x86_64.zip)\n\n    (_For Windows users_) Check out [this link](https://support.microsoft.com/en-us/help/827218/how-to-determine-whether-a-computer-is-running-a-32-bit-version-or-64) if you need help with determining if your computer is running a 32-bit version or 64-bit version of the Windows operating system.\n\n    _Note_ unfortunately, I could only test the project in OSX 10.11.6.\n\n2. Place the file in the root folder of this repository, and unzip (or decompress) the file.\n\n3. Install all the required dependencies:\n\n    The main requirements of this project are Python==3.6, numpy, matplotlib, jupyter, pytorch and unity-agents. To ease its installation, I recommend the following procedure:\n\n    - [Install miniconda](https://conda.io/docs/user-guide/install/index.html).\n\n      \u003e Feel free to skip this step, if you already have anaconda or miniconda installed in your machine.\n\n      \u003e For OSX users, I would recommend trying the step outlined [here](#Installation-for-conda-and-OSX-users)\n\n    - Creating the environment.\n\n      `conda create -n drlnd-navigation python=3.6`\n\n    - Activate the environment\n\n      `conda activate drlnd-navigation`\n\n    - Installing dependencies.\n\n      `pip install -r requirements.txt`\n\n### Installation for conda and OSX users\n\nYou can use the environment [YAML file](environment_osx.yml) provided with repo as follows:\n\n`conda env create -f environment_osx.yml`\n\n## Instructions\n\nLaunch a jupyter notebook and follow the tutorial in [Navigation.ipynb](Navigation.ipynb) to train your own agent!\n\n\u003e In case you close the shell running the jupyter server, don't forget to activate the environment. `conda activate drlnd-navigation`\n\n## Do you like the project?\n\nPlease gimme a ⭐️ in the GitHub banner 😉. I am also open for discussions especially accompany with ☕ or 🍺.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fescorciav%2Fdrlnd-navigation","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fescorciav%2Fdrlnd-navigation","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fescorciav%2Fdrlnd-navigation/lists"}
