Manual Installation Guide For Windows & Linux

This guide covers installation for different GPU generations and operating systems.

Requirements

- Compatible GPU (GTX 10XX - RTX 50XX)

Git Git Download
Build Tools for Visual Studio 2022 with C++ Extentions Vs2022 Download
Cuda Toolkit 12.8 or higher Cuda Toolkit Download
Nvidia Drivers Up to Date Nvidia Drivers Download
FFMPEG downloaded, unzipped & the bin folder on PATH FFMPEG Download
Python 3.10.9 Python Download
Miniconda Miniconda Download or Python venv

Installation for Nvidia GTX 10XX - RTX QUADRO - 50XX (Stable)

This installation uses PyTorch 2.6.0, Cuda 12.6 for GTX 10XX - RTX 30XX & PyTorch 2.7.1, Cuda 12.8 for RTX 40XX - 50XX which are well-tested and stable.

Unless you need absolutely to use Pytorch compilation (with RTX 50xx), it is not recommeneded to use PytTorch 2.8.0 as some System RAM memory leaks have been observed when switching models.

If you want to use the NV FP4 optimized kernels for RTX 50xx, you will need PyTorch 2.9.1 with Cuda 13.0

Flash Attention

Linux

Attention Modes

WanGP supports several attention implementations:

SDPA (default): Available by default with PyTorch
Sage: 30% speed boost with small quality cost
Sage2: 40% speed boost
Flash: Good performance, may be complex to install on Windows

Attention GPU Compatibility

RTX 10XX: SDPA
RTX 20XX: SPDA, Sage1
RTX 30XX, 40XX: SDPA, Flash Attention, Xformers, Sage1, Sage2/Sage2++
RTX 50XX: SDPA, Flash Attention, Xformers, Sage2/Sage2++ / Sage3

Performance Profiles

Choose a profile based on your hardware:

Profile 3 (LowRAM_HighVRAM): Loads entire model in VRAM, requires 24GB VRAM for 8-bit quantized 14B model
Profile 4 (LowRAM_LowVRAM): Default, loads model parts as needed, slower but lower VRAM requirement

Troubleshooting

Sage Attention Issues

If Sage attention doesn't work:

Check if Triton is properly installed
Clear Triton cache
Fallback to SDPA attention:
```
python wgp.py --attention sdpa
```

Memory Issues

Use lower resolution or shorter videos
Enable quantization (default)
Use Profile 4 for lower VRAM usage
Consider using 1.3B models instead of 14B models

For more troubleshooting, see TROUBLESHOOTING.md

Optional Kernels for INT4 / FP4 quantized support

These kernels will offer optimized INT4 / FP4 dequantization.

Please Note FP4 support is hardware dependent and will work only with RTX 50xx / sm120+ GPUs
