**Run `conda activate ai4beg` after creating the environment with `conda env create -f environment.yml` from the repository root.**

The Microsoft `AI-For-Beginners` repository provides a pre-configured Conda environment to ensure all course notebooks and examples run consistently across different systems. This guide walks through creating, activating, and verifying the `ai4beg` environment using the official [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml) specification.

## Prerequisites

Before setting up the environment, ensure you have:

- **Conda** installed (Anaconda or Miniconda)
- The repository cloned locally
- Terminal/command prompt open in the repository root directory

## Step 1: Create the Conda Environment

The repository's root [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml) file defines the complete Python stack for the curriculum, including **Jupyter**, **PyTorch**, **OpenCV**, **NumPy**, and other dependencies with pinned versions for reproducibility.

Run this command once to build the environment:

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

```

Conda resolves the dependency graph and installs all packages into an isolated environment named **`ai4beg`**. This process may take several minutes depending on your connection speed.

## Step 2: Activate the AI for Beginners Environment

Once creation completes, activate the environment for your current terminal session:

```bash
conda activate ai4beg

```

Upon successful activation, your shell prompt will display **`(ai4beg)`** as a prefix, indicating the environment is active.

## Step 3: Verify the Installation

Confirm that core packages load correctly:

```bash
python -c "import torch, cv2, numpy; print('Environment ready')"

```

Launch Jupyter to begin working with the course materials:

```bash
jupyter lab

# Alternative: jupyter notebook

```

## Managing the Environment

### Rebuilding After Updates

If the [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml) file changes (repository updates or custom modifications), remove and recreate the environment:

```bash
conda env remove -n ai4beg
conda env create -f environment.yml

```

### Daily Workflow

For each new working session:

```bash
cd /path/to/AI-For-Beginners
conda activate ai4beg
jupyter lab

```

## Key Configuration Files

- **[`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml)** — Primary environment definition at repository root
- **[`binder/environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/binder/environment.yml)** — Alternative specification for cloud platforms (Binder/Colab)

## Summary

- The `ai4beg` environment is defined in [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml) and provides all dependencies for the AI for Beginners curriculum
- Create once with `conda env create -f environment.yml`
- Activate each session with `conda activate ai4beg`
- Verify with `python -c "import torch, cv2, numpy; print('OK')"`
- Rebuild by removing and recreating when dependencies change

## Frequently Asked Questions

### What if `conda activate ai4beg` fails with "environment not found"?

The environment was not successfully created. Ensure you ran `conda env create -f environment.yml` from the repository root where [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml) exists. Check available environments with `conda env list`.

### Can I use the AI for Beginners materials without Conda?

Yes, though not recommended. The [`binder/environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/binder/environment.yml) supports cloud platforms, or you can manually install packages listed in [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml) into a virtual environment. Version conflicts are likely without Conda's dependency resolver.

### How do I update packages in the ai4beg environment?

Prefer rebuilding over in-place updates to maintain reproducibility: `conda env remove -n ai4beg` followed by `conda env create -f environment.yml`. For urgent updates, use `conda install` or `pip install` within the activated environment.

### Does the environment work on Apple Silicon (M1/M2)?

The [`environment.yml`](https://github.com/microsoft/AI-For-Beginners/blob/main/environment.yml) includes platform-appropriate dependencies. Conda resolves suitable PyTorch binaries automatically. If you encounter architecture-specific issues, prepend `CONDA_SUBDIR=osx-64` to force Intel-compatible packages under Rosetta 2.
