<br>

> **Note:** If your GPU is not listed above, it may not be supported by TheRock on Windows. Support status and future updates can be found in the [official documentation](https://github.com/ROCm/TheRock/blob/main/SUPPORTED_GPUS.md).

## Requirements

- Python 3.11 (recommended for Wan2GP - TheRock currently supports Python 3.11, 3.12, and 3.13).
- Windows 10/11

## Installation Environment

This installation uses PyTorch wheels built by TheRock.

### Installing Python

Download Python 3.11 from [python.org/downloads/windows](https://www.python.org/downloads/windows/). Press Ctrl+F and search for "3.11." to find the newest version available for installation.

Alternatively, you can use this direct link: [Python 3.11.9 (64-bit)](https://www.python.org/ftp/python/3.11.9/python-3.11.9-amd64.exe).

After installing, make sure `python --version` works in your terminal and returns `3.11.9`

If it doesn’t, you need to add Python to your PATH:

* Press the `Windows` key, type `Environment Variables`, and select `Edit the system environment variables`.
* In the `System Properties` window, click `Environment Variables…`.
* Under `User variables`, find `Path`, then click `Edit` → `New` and add the following entries (replace `<username>` with your Windows username):

```cmd

C:\Users\<username>\AppData\Local\Programs\Python\Launcher\

C:\Users\<username>\AppData\Local\Programs\Python\Python311\Scripts\

C:\Users\<username>\AppData\Local\Programs\Python\Python311\

```

> **Note:** If Python still doesn't show the correct version after updating PATH, try signing out and signing back in to Windows to apply the changes.

### Installing Git

Download Git from [git-scm.com/downloads/windows](https://git-scm.com/install/windows) and install it. The default installation options are fine.


## Installation Steps (Windows, using a Python `venv`)
> **Note:** The following commands are intended for use in the Windows Command Prompt (CMD).  
> If you are using PowerShell, some commands (like comments and activating the virtual environment) may differ.


### Step 1: Download and set up Wan2GP Environment

```cmd

:: Navigate to your desired install directory

cd \your-path-to-wan2gp



:: Clone the repository

git clone https://github.com/deepbeepmeep/Wan2GP.git

cd Wan2GP



:: Create virtual environment

python -m venv wan2gp-env



:: Activate the virtual environment

wan2gp-env\Scripts\activate

```

> **Note:** If you have multiple versions of Python installed, use `py -3.11 -m venv wan2gp-env` instead of `python -m venv wan2gp-env` to ensure the correct version is used.

### Step 2: Install ROCm/PyTorch by TheRock

**IMPORTANT:** Choose the correct index URL for your GPU family!

#### For gfx110X-all (RX 7900 XTX, RX 7800 XT, etc.):

```cmd

pip install --pre torch torchaudio torchvision rocm[devel] --index-url https://rocm.nightlies.amd.com/v2/gfx110X-all/

```

#### For gfx120X-all (RX 9060, RX 9070, etc.):

```cmd

pip install --pre torch torchaudio torchvision rocm[devel] --index-url https://rocm.nightlies.amd.com/v2/gfx120X-all/

```

#### For gfx1151 (Strix Halo iGPU):

```cmd

pip install --pre torch torchaudio torchvision rocm[devel] --index-url https://rocm.nightlies.amd.com/v2/gfx1151/

```

#### For gfx1150 (Radeon 890M - Strix Point):

```cmd

pip install --pre torch torchaudio torchvision rocm[devel] --index-url https://rocm.nightlies.amd.com/v2-staging/gfx1150/

```

#### For gfx103X-dgpu (RDNA 2):

```cmd

pip install --pre torch torchaudio torchvision rocm[devel] --index-url https://rocm.nightlies.amd.com/v2-staging/gfx103X-dgpu/

```

This will automatically install the latest PyTorch, torchaudio, and torchvision wheels with ROCm support.

### Step 3: Install Wan2GP Dependencies

```cmd

:: Install core dependencies

pip install -r requirements.txt

```

### Step 4: Verify Installation

```cmd

python -c "import torch; print('PyTorch:', torch.__version__); print('ROCm available:', torch.cuda.is_available()); print('Device:', torch.cuda.get_device_name(0) if torch.cuda.is_available() else 'No GPU')"

```

Expected output example:
```

PyTorch: 2.11.0+rocm7.12.0

ROCm available: True

Device: AMD Radeon RX 9070 XT

```

## Attention Modes

WanGP supports multiple attention implementations via [triton-windows](https://github.com/woct0rdho/triton-windows/).

First, install `triton-windows` in your virtual environment.
If you have an older version of Triton installed, uninstall it first.
ROCm SDK needs to be initialized.
Visual Studio environment should also be activated.

```cmd

pip uninstall triton

pip install triton-windows

rocm-sdk init

"C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat" >nul 2>&1

```

### Supported attention implementations

- **SageAttention V1** (Requires the `.post26` wheel or newer to fix Triton compilation issues without needing unofficial patches. Download it from [this](https://github.com/Comfy-Org/wheels/actions/runs/21343435018) URL)

```cmd

pip install "sageattention <2"

```

- **FlashAttention-2** (Only the Triton backend is supported): 
```cmd

git clone https://github.com/Dao-AILab/flash-attention.git

cd flash-attention

pip install ninja

pip install packaging

set FLASH_ATTENTION_TRITON_AMD_ENABLE=TRUE && python setup.py install

```

- **SDPA Flash**: Available by default in PyTorch on post-RDNA2 GPUs via AOTriton.

## Running Wan2GP

For future sessions, activate the environment every time if it isn't already activated, then run `python wgp.py`:

```cmd

cd \path-to\Wan2GP

wan2gp-env\Scripts\activate

:: Add the AMD-specific environment variables mentioned below here

python wgp.py

```

It is advised to set the following environment variables at the start of every new session (you can create a `.bat` file that activates your venv, sets these, then launches `wgp.py`):

```cmd

set ROCM_HOME=%ROCM_ROOT%

set PATH=%ROCM_ROOT%\lib\llvm\bin;%ROCM_BIN%;%PATH%

set CC=clang-cl

set CXX=clang-cl

set DISTUTILS_USE_SDK=1

set FLASH_ATTENTION_TRITON_AMD_ENABLE=TRUE

set TORCH_ROCM_AOTRITON_ENABLE_EXPERIMENTAL=1

```

MIOpen (AMD’s equivalent of NVIDIA’s cuDNN) is not yet fully stable on several architectures; it can cause out-of-memory errors (OOMs), crash the display driver, or significantly increase generation times. Currently, it is recommended to use fast mode by setting:

```cmd

set MIOPEN_FIND_MODE=FAST

```

Alternatively, you can disable MIOpen entirely by editing `wgp.py` and adding the following line below `import torch` (around line 51):

```cmd

...

:: /lines already in the file/

:: ...

:: import torch

torch.backends.cudnn.enabled = False # <-- Add this here

:: import gc

:: ...

...

```

To verify that it is disabled, or to enable verbose logging, you can set:

```cmd

set MIOPEN_ENABLE_LOGGING=1

set MIOPEN_ENABLE_LOGGING_CMD=1

set MIOPEN_LOG_LEVEL=5

```

## Troubleshooting

### GPU Not Detected

If `torch.cuda.is_available()` returns `False`:

1. **Verify your GPU is supported** - Check the [Supported GPUs](#supported-gpus) list above
2. **Check AMD drivers** - Ensure you have the latest AMD Adrenalin drivers installed
3. **Verify correct index URL** - Make sure you used the right GPU family index URL

### Installation Errors

**"Could not find a version that satisfies the requirement":**
- Double-check that you're using the correct `--index-url` for your GPU family. You can also try adding the `--pre` flag or replacing `/v2/` in the URL with `/v2/staging/`
- Ensure you're using Python 3.11, and not 3.10

**"No matching distribution found":**
- Your GPU architecture may not be supported
- Check that you've activated your virtual environment

### Performance Issues

- **Monitor VRAM usage** - Reduce batch size or resolution if running out of memory
- **Close GPU-intensive apps** - Apps with hardware acceleration enabled (browsers, Discord etc.).

### Known Issues

Windows packages are new and may be unstable.
