ComfyUI Node: Custom Ultralytics Model Loader

Custom Ultralytics Model Loader:

The CustomUltralyticsModelLoader node is designed to facilitate the loading of custom Ultralytics models for AI-based tasks, such as object detection and image analysis. This node allows you to specify a custom model path, making it highly flexible and adaptable to various use cases. By leveraging this node, you can easily integrate your own pre-trained models into your workflow, enabling more personalized and precise AI applications. The primary function of this node is to load a specified model from a directory, ensuring that you can work with models tailored to your specific needs without the hassle of manual loading and configuration.

Custom Ultralytics Model Loader Input Parameters:

model_path

The model_path parameter specifies the relative path to the custom Ultralytics model file you wish to load. This parameter is crucial as it directs the node to the exact location of the model within the models/ultralytics directory. The available options for this parameter are dynamically generated based on the .pt files present in the specified directory. This ensures that you can easily select from the available models without manually typing the path. The model_upload option is enabled, allowing you to upload new models directly into the directory. This parameter does not have minimum, maximum, or default values, as it depends on the files available in the directory.

Custom Ultralytics Model Loader Output Parameters:

ULTRALYTICS_MODEL

The ULTRALYTICS_MODEL output parameter represents the loaded Ultralytics model object. This output is essential as it provides the actual model that can be used for further inference tasks. The model object encapsulates all the necessary information and functionalities required to perform tasks such as object detection, classification, and more. By obtaining this output, you can seamlessly integrate the loaded model into your AI workflow, enabling you to leverage its capabilities for various applications.

Custom Ultralytics Model Loader Usage Tips:

• Ensure that your custom model files are placed in the models/ultralytics directory to be recognized by the node.
• Use the model_upload feature to easily add new models to the directory without manually moving files.
• Verify the model path before loading to avoid errors related to incorrect file paths.

Custom Ultralytics Model Loader Common Errors and Solutions:

Model file not found

• Explanation: This error occurs when the specified model file does not exist in the models/ultralytics directory.
• Solution: Ensure that the model file is correctly placed in the directory and that the model_path parameter is accurately specified.

Invalid model file format

• Explanation: This error happens if the selected file is not a valid .pt file.
• Solution: Verify that the model file is in the correct format and has a .pt extension.

Model loading failed

• Explanation: This error indicates that there was an issue while loading the model, possibly due to file corruption or incompatibility.
• Solution: Check the integrity of the model file and ensure it is compatible with the Ultralytics framework. Re-download or retrain the model if necessary.
