Example Usage Script: BLIP

In this example, we will demonstrate how to use Nataili to generate captions for an image using BLIP.

Import Required Libraries

We start by importing the necessary libraries:

from PIL import Image
from nataili.blip import Caption
from nataili.model_manager.blip import BlipModelManager
from nataili.util.logger import logger

• Image from the Python Imaging Library (PIL) is used to open the image file.
• Caption from the nataili.blip module is the service class used to generate captions.
• BlipModelManager from the nataili.model_manager.blip module is the model manager used to download and manage the BLIP model.
• logger from the nataili.util.logger module is used to log the generated caption.

Open the Image

Next, we open the image file:

image = Image.open("01.png")

Replace "01.png" with the path to the image file you want to use.

Create an Instance of the Model Manager

We create an instance of the BlipModelManager:

mm = BlipModelManager()

Load the BLIP Model

We use the load function of the model manager to download and load the BLIP model:

mm.load("BLIP")

The "BLIP" argument is the key used to identify the BLIP model in the model database.

Create a Caption Object

We create a Caption object, passing in the loaded BLIP model:

blip = Caption(mm.loaded_models["BLIP"])

Generate the Caption

Finally, we use the __call__ function of the Caption object to generate the caption:

logger.generation(f"caption: {blip(image)}")

The generated caption will be logged using the logger object. The format of the log message is "caption: [generated caption]".

With these steps, we have successfully used Nataili to generate captions for an image using BLIP.
