What are the system requirements for Fooocus AI?

Fooocus AI is a free, open-source tool that transforms text descriptions into images using artificial intelligence. Designed with user-friendliness in mind, it automates many settings, allowing users to focus on crafting prompts and exploring creative possibilities. Running Fooocus locally provides enhanced control and privacy compared to web-based alternatives.

System Requirements

To ensure optimal performance with Fooocus AI, your system should meet the following minimum specifications:

• Operating System: Windows, Linux, or macOS
• Graphics Processing Unit (GPU):
  • NVIDIA GPUs:
    • RTX 4000 series: Minimum 4GB VRAM
    • RTX 3000 series: Minimum 4GB VRAM
    • RTX 2000 series: Minimum 4GB VRAM
    • GTX 1000 series: Minimum 8GB VRAM (6GB may work but is uncertain)
    • GTX 900 series: Minimum 8GB VRAM
  • AMD GPUs:
    • Windows: Minimum 8GB VRAM (via DirectML)
    • Linux: Minimum 8GB VRAM (via ROCm)
• System Memory (RAM): At least 8GB
• Storage Space: Ensure at least 40GB of free space to accommodate model downloads and virtual memory needs.
• Virtual Memory (Swap Space): Enabled, especially crucial for systems with minimum RAM.

For macOS users with M1 or M2 chips, Fooocus operates using the Metal Performance Shaders (MPS) framework. However, performance may be slower compared to systems with dedicated GPUs.

Installation Steps

For Windows Users:

1. Download: Obtain the latest version of Fooocus from the official GitHub repository.
2. Extract Files: Unzip the downloaded package to your chosen directory.
3. Launch Application: Run the run.bat file. On the first launch, Fooocus will automatically download the necessary models.

For Linux Users:

1. Clone Repository:bashCopyEditgit clone https://github.com/lllyasviel/Fooocus.git cd Fooocus
2. Set Up Environment:bashCopyEditconda env create -f environment.yaml conda activate fooocus
3. Install Dependencies:bashCopyEditpip install -r requirements_versions.txt
4. Launch Application:bashCopyEditpython entry_with_update.py

For macOS Users:

1. Install Dependencies: Ensure Python 3.10 and Conda are installed.
2. Clone Repository:bashCopyEditgit clone https://github.com/lllyasviel/Fooocus.git cd Fooocus
3. Set Up Environment:bashCopyEditconda env create -f environment.yaml conda activate fooocus
4. Install Required Packages:bashCopyEditpip install -r requirements_versions.txt
5. Launch Application:bashCopyEditpython entry_with_update.py

During the initial launch, Fooocus will download default models to the Fooocus\models\checkpoints directory. For inpainting features, an additional model (inpaint_v26.fooocus.patch, approximately 1.28GB) will be downloaded to the Fooocus\models\inpaint folder upon first use.

Frequently Asked Questions (FAQs)

1. What if I encounter a “MetadataIncompleteBuffer” or “PytorchStreamReader” error?
   • These errors suggest that the model files might be corrupted. It’s recommended to delete the existing model files and allow Fooocus to re-download them automatically.
2. My image generation is slower than expected. What can I do?
   • Ensure your NVIDIA GPU drivers are up-to-date. Some users have reported performance issues with drivers above version 532; reverting to version 531 has resolved speed concerns for some.
3. What does “RuntimeError: CPUAllocator” mean, and how can I fix it?
   • This error indicates insufficient virtual memory. Verify that your system’s virtual memory (swap space) is enabled and has adequate space. On Windows, you can adjust virtual memory settings through the System Properties.
4. Can I run Fooocus without a dedicated GPU?
   • While possible, running Fooocus solely on a CPU is significantly slower. For a smoother experience, a compatible GPU is recommended.
5. Is there support for AMD GPUs?
   • Yes, Fooocus supports AMD GPUs. On Windows, it utilizes DirectML, and on Linux, it operates via ROCm. Note that AMD support is currently in beta, and performance may vary.
6. How much disk space is required for Fooocus?
   • It’s advisable to have at least 40GB of free disk space. This accommodates model downloads and ensures sufficient virtual memory for operations.
7. Are there different model presets available?
   • Yes, starting from version 2.1.60, Fooocus offers different model presets, including run_anime.bat and run_realistic.bat. These presets automatically download the necessary models upon first use.
8. Can I use Fooocus on macOS systems?
   • Yes, Fooocus is compatible with macOS, particularly on M1 and M2 chips. However, due to the lack of a dedicated GPU, performance may be slower compared to systems equipped with NVIDIA GPUs.
