In this notebook, **you'll train a Deep Q-Learning agent** playing Space Invaders using [RL Baselines3 Zoo](https://github.com/DLR-RM/rl-baselines3-zoo), a training framework based on [Stable-Baselines3](https://stable-baselines3.readthedocs.io/en/master/) that provides scripts for training, evaluating agents, tuning parameters, plotting results and recording videos.

We strongly recommend students **to use Google Colab for the hands-on exercises instead of running them on their personal computers**.
By using Google Colab, **you can focus on learning and experimenting without worrying about the technical aspects of setting up your environments**.
To validate this hands-on for the certification process, you need to push your trained model to the Hub and **get a result of >= 200**.
To find your result, go to the leaderboard and find your model, **the result = mean_reward - std of reward**

You could directly install from the Python package (`pip install rl_zoo3`), but since we want **the full installation with extra environments and dependencies**, we're going to clone the `RL-Baselines3-Zoo` repository and install from source.
```bash

## Train our Deep Q-Learning Agent to Play Space Invaders 👾
To train an agent with RL-Baselines3-Zoo, we just need to do two things:
1. We define the hyperparameters in `/content/rl-baselines3-zoo/hyperparams/dqn.yml`
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/notebooks/unit3/hyperparameters.png" alt="DQN Hyperparameters">
1. Create a hyperparameter config file that will contain our training hyperparameters called `dqn.yml`.
This is a template example:

Here we see that:
- We use the `Atari Wrapper` that does the pre-processing (Frame reduction, grayscale, stack four frames),
- We use the `CnnPolicy`, since we use Convolutional layers to process the frames.
- We train the model for 10 million `n_timesteps`.
- Memory (Experience Replay) size is 100000, i.e. the number of experience steps you saved to train again your agent with.

💡 My advice is to **reduce the training timesteps to 1M,** which will take about 90 minutes on a P100. `!nvidia-smi` will tell you what GPU you're using. At 10 million steps, this will take about 9 hours, which could likely result in Colab timing out. I recommend running this on your local computer (or somewhere else). Just click on: `File>Download`.

In terms of hyperparameters optimization, my advice is to focus on these 3 hyperparameters:
- `learning_rate`
- `buffer_size (Experience Memory size)`
- `batch_size`
As a good practice, you need to **check the documentation to understand what each hyperparameter does**: https://stable-baselines3.readthedocs.io/en/master/modules/dqn.html#parameters
