How to Install and Use FLUX 🛠️

First, ensure that your computer has Git and Python 3.10 installed! Next, follow these steps to easily install FLUX locally:

cd $HOME && git clone https://github.com/black-forest-labs/flux

• cd $HOME: This command switches your current working directory to the user’s home directory for better path management.
• git clone https://github.com/black-forest-labs/flux: This uses Git to clone the FLUX code repository from GitHub, allowing you to easily operate and modify this excellent code locally!

cd $HOME/flux

• cd $HOME/flux: Enter the just-cloned FLUX project directory to access more project functions and resources.

python3.10 -m venv .venv

• python3.10 -m venv .venv: Create a virtual environment named .venv to effectively isolate project dependencies and ensure that other projects’ packages do not affect the current project—such a smart move!

source .venv/bin/activate

• source .venv/bin/activate: Activate your newly created virtual environment! ✨ From now on, any Python packages installed will only apply to this environment, ensuring your project remains clean and efficient.

pip install -e ".[all]"

• pip install -e ".[all]": This installs FLUX and all its related dependencies in editable mode. This way, any changes you make to the source code of FLUX will automatically update the installed packages, making work much more flexible!

Using FLUX Models 🖼️

FLUX provides a variety of models for image generation and editing, suitable for various application needs. Check out the classification below, and you’re sure to find a model that fits your needs:

The table clearly presents the names, purposes, and HuggingFace links of FLUX models, allowing you to choose the most suitable model based on project needs and discover different functionalities to kickstart your creative journey!

Using the FLUX API 🌐

Don’t forget, FLUX’s API provides users with powerful interfaces to access its models! First, you need to register and obtain an API key at api.bfl.ml to easily start your journey! 🤩 When using the API key, you can set it up in the terminal like this:

export BFL_API_KEY=<your_key_here>

• export BFL_API_KEY=<your_key_here>: Set the API key as an environment variable so that subsequent API requests can recognize and use this key!

In your code, you can also import the necessary modules as follows:

from flux.api import ImageRequest

• from flux.api import ImageRequest: This line imports the ImageRequest class from the flux module, which you will use to generate image requests.

Next, use the following code to send an image request and see the results:

request = ImageRequest("A beautiful beach", name="flux.1.1-pro")

• request = ImageRequest("A beautiful beach", name="flux.1.1-pro"): This creates an image request where "A beautiful beach" is the descriptive text for the image to be generated, and name="flux.1.1-pro" indicates the model used for image generation.

request.url

• request.url: This retrieves the link to the generated image, and will block until the generation is complete, suitable for subsequent processes!

request.bytes

• request.bytes: This returns the byte data of the generated image, which can be used to save a file or carry out further processing—so easy!

request.save("outputs/api.jpg")

• request.save("outputs/api.jpg"): This saves the generated image as api.jpg, allowing for easy viewing and management later~🎉

request.image

• request.image: This returns the generated image object, which can be easily displayed or manipulated using the PIL library!

Using FLUX from the Command Line 💻

Of course, another convenient way to use FLUX is through the command line! Just input the following command in your terminal to easily send an image request:

$ python -m flux.api --prompt="A beautiful beach" url

• python -m flux.api --prompt="A beautiful beach" url: This generates an image using the specified prompt text and returns the URL of the generated image; getting results is that simple!

# Generate and save the results
$ python -m flux.api --prompt="A beautiful beach" save outputs/api

• python -m flux.api --prompt="A beautiful beach" save outputs/api: This command will generate the image and directly save it as outputs/api, making it convenient for later use!

# Open the image directly
$ python -m flux.api --prompt="A beautiful beach" image show

• python -m flux.api --prompt="A beautiful beach" image show: This opens the generated image directly for quick viewing, allowing you to see the generated results in one click!

With these simple and easy steps, you can easily install FLUX and create magnificent images using its API or command-line interface. If you want to delve deeper into more features, head to its official documentation for more detailed information! 📚
