**Use `git clone --filter=blob:none --sparse` followed by `git sparse-checkout set --no-cone '/*' '!translations' '!translated_images'` to download only the core curriculum, skipping the 50+ language translations and localized image assets that add hundreds of megabytes to the repository.**

The **microsoft/AI-For-Beginners** repository is a comprehensive 12-week curriculum covering artificial intelligence fundamentals from symbolic AI to neural networks and computer vision. While the repository includes extensive translation files and localized image assets for global accessibility, these directories significantly inflate the repository size. For learners who only need the English-language lessons and code examples, a **sparse git checkout** provides a lightweight alternative that excludes the `translations/` and `translated_images/` directories while preserving every Jupyter notebook, Python script, and configuration file needed to run the course.

## Why Exclude Translations from Your Clone?

The repository architecture separates content into functional directories. According to the source code structure, the top-level components include:

- **`lessons/`** – Core curriculum containing Jupyter notebooks and markdown guides for AI topics including neural networks, computer vision, and NLP
- **`examples/`** – Self-contained Python scripts for quick experimentation (e.g., [`01-hello-ai-world.py`](https://github.com/microsoft/AI-For-Beginners/blob/main/01-hello-ai-world.py), [`02-simple-neural-network.py`](https://github.com/microsoft/AI-For-Beginners/blob/main/02-simple-neural-network.py))
- **`etc/quiz-app/`** – Vue.js-based quiz application with [`package.json`](https://github.com/microsoft/AI-For-Beginners/blob/main/package.json) and [`src/App.vue`](https://github.com/microsoft/AI-For-Beginners/blob/main/src/App.vue)
- **[`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml)** – Conda environment definition specifying PyTorch, OpenCV, NumPy, and scikit-learn dependencies
- **`translations/`** – 50+ language-specific README files and lesson translations (excluded in sparse checkout)
- **`translated_images/`** – Large image assets used by translated lessons (excluded in sparse checkout)

Removing the `translations` and `translated_images` directories reduces the repository from several hundred megabytes down to a few dozen megabytes, enabling faster cloning on low-bandwidth connections and reducing local storage requirements.

## Performing the Sparse Git Checkout

The official [`README.md`](https://github.com/microsoft/AI-For-Beginners/blob/main/README.md) documents this technique in the "Prefer to Clone Locally?" section. The process uses Git's sparse-checkout feature with the `--filter=blob:none` option to avoid downloading file contents initially, then defines a checkout set that includes all top-level paths while explicitly negating the translation directories.

### Unix-like Systems (Linux/macOS)

Run these commands in bash or zsh:

```bash
git clone --filter=blob:none --sparse https://github.com/microsoft/AI-For-Beginners.git
cd AI-For-Beginners
git sparse-checkout set --no-cone '/*' '!translations' '!translated_images'

```

### Windows Command Prompt

For Windows CMD, use double quotes instead of single quotes:

```cmd
git clone --filter=blob:none --sparse https://github.com/microsoft/AI-For-Beginners.git
cd AI-For-Beginners
git sparse-checkout set --no-cone "/*" "!translations" "!translated_images"

```

The `--no-cone` flag ensures that the pattern matching works with the exclusion rules (`!`), preventing Git from automatically adding parent directories that would otherwise force-include the translation folders.

## What Gets Included in the Lightweight Clone

After executing the sparse checkout commands, your local copy contains all functional components of the curriculum while omitting the translation assets:

**Included directories:**
- **`lessons/`** – Complete curriculum with notebooks like `lessons/3-NeuralNetworks/03-Perceptron/Perceptron.ipynb` and `lessons/4-ComputerVision/07-ConvNets/ConvNetsPyTorch.ipynb`
- **`examples/`** – Quick-start Python scripts demonstrating pattern recognition and image classification
- **`etc/quiz-app/`** – Full Vue.js application source code and build configuration
- **Configuration files** – [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml), [`requirements.txt`](https://github.com/microsoft/AI-For-Beginners/blob/main/requirements.txt), [`.devcontainer/devcontainer.json`](https://github.com/microsoft/AI-For-Beginners/blob/main/.devcontainer/devcontainer.json), and [`binder/postBuild.sh`](https://github.com/microsoft/AI-For-Beginners/blob/main/binder/postBuild.sh)

**Excluded directories:**
- **`translations/`** – All 50+ localized README files (e.g., [`translations/zh-TW/README.md`](https://github.com/microsoft/AI-For-Beginners/blob/main/translations/zh-TW/README.md), [`translations/ja/README.md`](https://github.com/microsoft/AI-For-Beginners/blob/main/translations/ja/README.md))
- **`translated_images/`** – Localized image assets such as `translated_images/zh-TW/vae.webp` and `translated_images/bn/yolo.webp`

## Configuring the Environment After Checkout

Once you have the sparse clone, set up the Python environment using the provided Conda configuration:

1. **Create the environment** using [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml):

   ```bash
   conda env create -f environment.yml
   ```

2. **Activate the environment** (named `ai4beg`):

   ```bash
   conda activate ai4beg
   ```

3. **Verify installation** by importing the key libraries:

   ```bash
   python -c "import torch, cv2, numpy; print('All libraries loaded successfully')"
   ```

4. **Run example scripts** to validate the setup:

   ```bash
   python examples/01-hello-ai-world.py
   python examples/02-simple-neural-network.py
   ```

5. **Launch Jupyter** to access the lesson notebooks:

   ```bash
   jupyter notebook lessons/3-NeuralNetworks/03-Perceptron/Perceptron.ipynb
   ```

The [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml) file specifies Python 3.x, PyTorch, OpenCV, Matplotlib, and scikit-learn, ensuring all notebooks in the `lessons/` directory execute without requiring the excluded translation files.

## Summary

- **Sparse checkout** with `--filter=blob:none` and `--sparse` enables partial cloning of the microsoft/AI-For-Beginners repository
- **Excluding `translations/` and `translated_images/`** reduces repository size from hundreds of megabytes to a few dozen megabytes
- **Platform-specific syntax** requires single quotes for Unix-like shells and double quotes for Windows CMD in the `sparse-checkout set` command
- **Core functionality remains intact**, including all Jupyter notebooks in `lessons/`, Python scripts in `examples/`, the Vue.js quiz app in `etc/quiz-app/`, and environment configuration files
- **Post-clone setup** requires only `conda env create -f environment.yml` to establish the full AI development environment

## Frequently Asked Questions

### What is a sparse checkout in Git?

A **sparse checkout** is a Git feature that allows you to check out only specific directories from a repository while excluding others. By using `git sparse-checkout set` with path patterns, you can create a working directory that contains only the files you need, which is particularly useful for large repositories like microsoft/AI-For-Beginners that contain extensive translation assets not required by all users.

### Why does the AI for Beginners repository include translations?

The repository includes **50+ language translations** to support global accessibility and inclusive education, as maintained by Microsoft’s open-source education initiative. These translations reside in `translations/` and `translated_images/`, but they significantly increase repository size and are not required for running the Python code or Jupyter notebooks, making them ideal candidates for exclusion via sparse checkout.

### Can I add translations back after a sparse checkout?

Yes, you can modify your sparse-checkout patterns at any time using `git sparse-checkout add translations/` to include specific translation directories, or `git sparse-checkout set --no-cone '/*'` to include all files. Git will then fetch the excluded blob objects from the remote repository and populate the previously excluded directories in your working tree.

### Does sparse checkout affect the Git history?

No, **sparse checkout does not alter the Git history or commit graph**. It only affects which files appear in your working directory and the index. The full repository history remains available in the `.git` directory, and you can still access all commits, branches, and tags; you simply do not have local copies of the excluded files' contents unless you explicitly add them later.
