ComfyUI Node: Image To Prompt

Image To Prompt:

The easy imageInterrogator node is designed to convert images into descriptive text prompts using advanced AI models. This node leverages the power of the CLIP Interrogator to analyze the content of an image and generate a textual description that captures its essence. This can be particularly useful for AI artists who want to generate prompts for text-to-image models or for those who need to catalog and describe their image collections. The node offers various modes to balance between speed and accuracy, making it adaptable to different needs and computational resources.

Image To Prompt Input Parameters:

image

This parameter accepts the image that you want to convert into a text prompt. The image should be in a format that the node can process, typically a tensor representation of the image. The quality and content of the image will directly impact the generated prompt.

mode

This parameter determines the method used to generate the text prompt. The available options are fast, classic, best, and negative.

• fast: Prioritizes speed over accuracy, useful for quick results.
• classic: Balances between speed and accuracy, providing a good middle ground.
• best: Focuses on generating the most accurate and detailed prompts, but may take longer to process.
• negative: Generates a prompt that describes what the image is not, useful for certain types of image analysis. There is no default value, so you must choose one of the options.

use_lowvram

This boolean parameter allows you to enable or disable low VRAM mode. When set to True, the node will use less GPU memory, which can be useful if you are working with limited resources. The default value is True.

Image To Prompt Output Parameters:

prompt

This output parameter provides the generated text prompt as a string. The prompt is a descriptive text that captures the essence of the input image, based on the selected mode. This can be used for various purposes, such as generating new images, cataloging, or further analysis.

Image To Prompt Usage Tips:

• For quick results, use the fast mode, but be aware that the generated prompts may be less detailed.
• If you need highly accurate and detailed prompts, opt for the best mode, but ensure you have sufficient computational resources as it may take longer to process.
• Use the negative mode to generate prompts that describe what the image is not, which can be useful for certain types of image analysis or filtering.
• Enable use_lowvram if you are working on a machine with limited GPU memory to avoid running into memory issues.

Image To Prompt Common Errors and Solutions:

Unknown mode <mode>

• Explanation: This error occurs when an invalid mode is provided to the node.
• Solution: Ensure that the mode parameter is set to one of the following valid options: fast, classic, best, or negative.

CUDA out of memory

• Explanation: This error occurs when the GPU runs out of memory during the processing of the image.
• Solution: Enable the use_lowvram option to reduce GPU memory usage, or try processing smaller images.

Model loading failed

• Explanation: This error occurs when the node fails to load the required AI model.
• Solution: Ensure that the necessary models are installed and accessible. You may need to reinstall the clip_interrogator package or check the model paths.

Image format not supported

• Explanation: This error occurs when the input image is in an unsupported format.
• Solution: Convert the image to a supported format, such as a tensor representation, before passing it to the node.
