+ "\n",
+ "In this hands-on project, we will first implement a simple RL algorithm and apply it to solve the CartPole-v1 environment. Once we become familiar with the basic workflow, we will learn to use various tools for machine learning model training, monitoring, and sharing, by applying these tools to train a robotic arm.\n",
+ "\n",
+ "## To be handed in\n",
+ "\n",
+ "This work must be done individually. The expected output is a repository named `hands-on-rl` on https://gitlab.ec-lyon.fr. \n",
+ "\n",
+ "We assume that `git` is installed, and that you are familiar with the basic `git` commands. (Optionnaly, you can use GitHub Desktop.)\n",
+ "We also assume that you have access to the [ECL GitLab](https://gitlab.ec-lyon.fr/). If necessary, please consult [this tutorial](https://gitlab.ec-lyon.fr/edelland/inf_tc2/-/blob/main/Tutoriel_gitlab/tutoriel_gitlab.md).\n",
+ "\n",
+ "Your repository must contain a `README.md` file that explains **briefly** the successive steps of the project. It must be private, so you need to add your teacher as \"developer\" member.\n",

+ "Throughout the subject, you will find a 🛠 symbol indicating that a specific production is expected.\n",

+ "\n",
+ "In this hands-on project, we will first implement a simple RL algorithm and apply it to solve the CartPole-v1 environment. Once we become familiar with the basic workflow, we will learn to use various tools for machine learning model training, monitoring, and sharing, by applying these tools to train a robotic arm.\n",
+ "\n",
+ "## To be handed in\n",
+ "\n",
+ "This work must be done individually. The expected output is a repository named `hands-on-rl` on https://gitlab.ec-lyon.fr. \n",
+ "\n",
+ "We assume that `git` is installed, and that you are familiar with the basic `git` commands. (Optionnaly, you can use GitHub Desktop.)\n",
+ "We also assume that you have access to the [ECL GitLab](https://gitlab.ec-lyon.fr/). If necessary, please consult [this tutorial](https://gitlab.ec-lyon.fr/edelland/inf_tc2/-/blob/main/Tutoriel_gitlab/tutoriel_gitlab.md).\n",
+ "\n",
+ "Your repository must contain a `README.md` file that explains **briefly** the successive steps of the project. It must be private, so you need to add your teacher as \"developer\" member.\n",

+ "Throughout the subject, you will find a 🛠 symbol indicating that a specific production is expected.\n",

+ "The last commit is due before 11:59 pm on March 5, 2024. Subsequent commits will not be considered.\n",
+ "\n",
+ "> ⚠️ **Warning**\n",
+ "> Ensure that you only commit the files that are requested. For example, your directory should not contain the generated `.zip` files, nor the `runs` folder... At the end, your repository must contain one `README.md`, three python scripts, and optionally image files for the plots.\n",
