We highly recommend using a `venv` to avoid issues.


For Windows:
```bash
python -m venv venv
venv\Scripts\activate
pip install -r requirements.txt
```
**For Windows:**

It is highly recommended to use Python 3.10 for Windows for best compatibility with all features and dependencies.

**Automated Setup (Recommended):**

1. **Run the setup script:**
Double-click `setup_windows.bat` or run it from your command prompt:
```batch
setup_windows.bat
```
This script will:
* Check if Python is in your PATH.
* Warn if `ffmpeg` is not found (see "Manual Steps / Notes" below for ffmpeg help).
* Create a virtual environment named `.venv` (consistent with macOS setup).
* Activate the virtual environment for the script's session.
* Upgrade pip.
* Install Python packages from `requirements.txt`.
Wait for the script to complete. It will pause at the end; press any key to close the window if you double-clicked it.

2. **Run the application:**
After setup, use the provided `.bat` scripts to run the application. These scripts automatically activate the correct virtual environment:
* `run_windows.bat`: Runs the application with the CPU execution provider by default. This is a good starting point if you don't have a dedicated GPU or are unsure.
* `run-cuda.bat`: Runs with the CUDA (NVIDIA GPU) execution provider. Requires an NVIDIA GPU and CUDA Toolkit installed (see GPU Acceleration section).
* `run-directml.bat`: Runs with the DirectML (AMD/Intel GPU on Windows) execution provider.

Example: Double-click `run_windows.bat` to launch the UI, or run from a command prompt:
```batch
run_windows.bat --source path\to\your_face.jpg --target path\to\video.mp4
```

**Manual Steps / Notes:**

* **Python:** Ensure Python 3.10 is installed and added to your system's PATH. You can download it from [python.org](https://www.python.org/downloads/).
* **ffmpeg:**
* `ffmpeg` is required for video processing. The `setup_windows.bat` script will warn if it's not found in your PATH.
* An easy way to install `ffmpeg` on Windows is to open PowerShell as Administrator and run:
```powershell
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1')); choco install ffmpeg -y
```
Alternatively, download from [ffmpeg.org](https://ffmpeg.org/download.html), extract the files, and add the `bin` folder (containing `ffmpeg.exe`) to your system's PATH environment variable. The original README also linked to a [YouTube guide](https://www.youtube.com/watch?v=OlNWCpFdVMA) or `iex (irm ffmpeg.tc.ht)` via PowerShell.
* **Visual Studio Runtimes:** If you encounter errors during `pip install` for packages that compile C code (e.g., some scientific computing or image processing libraries), you might need the [Visual Studio Build Tools (or Runtimes)](https://visualstudio.microsoft.com/visual-cpp-build-tools/). Ensure "C++ build tools" (or similar workload) are selected during installation.
* **Virtual Environment (Manual Alternative):** If you prefer to set up the virtual environment manually instead of using `setup_windows.bat`:
```batch
python -m venv .venv
.venv\Scripts\activate.bat
python -m pip install --upgrade pip
python -m pip install -r requirements.txt
```
(The new automated scripts use `.venv` as the folder name for consistency with the macOS setup).

For Linux:
```bash
# Ensure you use the installed Python 3.10

**For macOS:**

Apple Silicon (M1/M2/M3) requires specific setup:

```bash
# Install Python 3.10 (specific version is important)
brew install [email protected]

# Install tkinter package (required for the GUI)
brew install [email protected]

# Create and activate virtual environment with Python 3.10
python3.10 -m venv venv
source venv/bin/activate

# Install dependencies
pip install -r requirements.txt
```
For a streamlined setup on macOS, use the provided shell scripts:

1. **Make scripts executable:**
Open your terminal, navigate to the cloned `Deep-Live-Cam` directory, and run:
```bash
chmod +x setup_mac.sh
chmod +x run_mac*.sh
```

2. **Run the setup script:**
This will check for Python 3.9+, ffmpeg, create a virtual environment (`.venv`), and install required Python packages.
```bash
./setup_mac.sh
```
If you encounter issues with specific packages during `pip install` (especially for libraries that compile C code, like some image processing libraries), you might need to install system libraries via Homebrew (e.g., `brew install jpeg libtiff ...`) or ensure Xcode Command Line Tools are installed (`xcode-select --install`).

3. **Activate the virtual environment (for manual runs):**
After setup, if you want to run commands manually or use developer tools from your terminal session:
```bash
source .venv/bin/activate
```
(To deactivate, simply type `deactivate` in the terminal.)

4. **Run the application:**
Use the provided run scripts for convenience. These scripts automatically activate the virtual environment.
* `./run_mac.sh`: Runs the application with the CPU execution provider by default. This is a good starting point.
* `./run_mac_cpu.sh`: Explicitly uses the CPU execution provider.
* `./run_mac_coreml.sh`: Attempts to use the CoreML execution provider for potential hardware acceleration on Apple Silicon and Intel Macs.
* `./run_mac_mps.sh`: Attempts to use the MPS (Metal Performance Shaders) execution provider, primarily for Apple Silicon Macs.

Example of running with specific source/target arguments:
```bash
./run_mac.sh --source path/to/your_face.jpg --target path/to/video.mp4
```
Or, to simply launch the UI:
```bash
./run_mac.sh
```

**Important Notes for macOS GPU Acceleration (CoreML/MPS):**

* The `setup_mac.sh` script installs packages from `requirements.txt`, which typically includes a general CPU-based version of `onnxruntime`.
* For optimal performance on Apple Silicon (M1/M2/M3) or specific GPU acceleration, you might need to install a different `onnxruntime` package *after* running `setup_mac.sh` and while the virtual environment (`.venv`) is active.
* **Example for `onnxruntime-silicon` (often requires Python 3.10 for older versions like 1.13.1):**
The original `README` noted that `onnxruntime-silicon==1.13.1` was specific to Python 3.10. If you intend to use this exact version for CoreML:
```bash
# Ensure you are using Python 3.10 if required by your chosen onnxruntime-silicon version
# After running setup_mac.sh and activating .venv:
# source .venv/bin/activate

pip uninstall onnxruntime onnxruntime-gpu # Uninstall any existing onnxruntime
pip install onnxruntime-silicon==1.13.1 # Or your desired version

# Then use ./run_mac_coreml.sh
```
Check the ONNX Runtime documentation for the latest recommended packages for Apple Silicon.
* **For MPS with ONNX Runtime:** This may require a specific build or version of `onnxruntime`. Consult the ONNX Runtime documentation. For PyTorch-based operations (like the Face Enhancer or Hair Segmenter if they were PyTorch native and not ONNX), PyTorch should automatically try to use MPS on compatible Apple Silicon hardware if available.
* **User Interface (Tkinter):** If you encounter errors related to `_tkinter` not being found when launching the UI, ensure your Python installation supports Tk. For Python installed via Homebrew, this is usually `python-tk` (e.g., `brew install [email protected]` or `brew install [email protected]`, matching your Python version).

** In case something goes wrong and you need to reinstall the virtual environment **

suggestion: Device placement for hair segmenter model is not configurable.

Consider making device placement configurable or automatically align it with other models to prevent unnecessary CPU-GPU transfers.

    device = kwargs.get("device", "cpu") if "kwargs" in locals() else "cpu"

  • You will need to update the function signature to accept a device parameter (e.g., def your_function(..., device="cpu"):) and ensure that device is passed in when calling this function.
  • If you want to automatically align the device with other models, you should retrieve the device from those models and pass it here.
  • If this is inside a class or larger function, ensure device is available in the scope or passed as an argument.

suggestion: Hardcoded label index for hair segmentation.

Consider making the label index configurable or retrieving it dynamically from the model config to prevent issues if the label mapping changes.

Suggested implementation:

    segmentation_map = upsampled_logits.argmax(dim=1).squeeze().cpu().numpy().astype(np.uint8)

    # Use configurable label index for hair segmentation
    hair_label_index = getattr(HAIR_SEGMENTER_MODEL, "hair_label_index", 2)

    """

    Args:
        image_np: Input image as a numpy array.
        hair_label_index: Optional; index of the hair label in the segmentation map. If not provided, will use model config or default to 2.

    Returns:
        Binary mask of hair segmentation.

    return np.where(segmentation_map == hair_label_index, 255, 0).astype(np.uint8)
  • If you have a model config or class that provides label mappings, set HAIR_SEGMENTER_MODEL.hair_label_index accordingly when loading the model.
  • Update any calls to segment_hair to pass the hair_label_index if you want to override the default.
  • If you want to retrieve the label index from a config file or mapping, add that logic where the model is loaded and set HAIR_SEGMENTER_MODEL.hair_label_index.
