Checkpoint Selector Description

Efficiently manage and select model checkpoints in ComfyUI for AI art projects.

Checkpoint Selector:

The Checkpoint Selector node is designed to help you easily select and manage your model checkpoints within the ComfyUI environment. This node provides a streamlined way to access and choose from a list of available checkpoints, ensuring that you can quickly load the desired model configurations for your AI art projects. By utilizing this node, you can efficiently switch between different model states, facilitating experimentation and iteration in your creative process. The primary goal of the Checkpoint Selector is to enhance your workflow by providing a user-friendly interface for checkpoint management, making it easier to leverage various model versions without delving into complex file handling.

Checkpoint Selector Input Parameters:


The ckpt_name parameter allows you to specify the name of the checkpoint you wish to select. This parameter pulls from a list of available checkpoint filenames, ensuring that you can choose from the models you have previously saved or downloaded. By selecting the appropriate checkpoint, you can load the corresponding model state into your workflow. This parameter is crucial for ensuring that the correct model configuration is used, impacting the results of your AI art generation. There are no minimum or maximum values for this parameter, as it is a selection from a predefined list of filenames.

Checkpoint Selector Output Parameters:


The ckpt_name output parameter returns the name of the selected checkpoint. This output is essential as it provides the identifier for the chosen model state, which can then be used in subsequent nodes or processes within your workflow. By outputting the checkpoint name, the node ensures that the correct model configuration is referenced, maintaining consistency and accuracy in your AI art generation tasks.

Checkpoint Selector Usage Tips:

  • Ensure that your checkpoints are properly named and organized in the designated directory to make selection easier and more intuitive.
  • Use descriptive names for your checkpoints to quickly identify the model configurations and versions, facilitating smoother transitions between different states.

Checkpoint Selector Common Errors and Solutions:

Checkpoint not found

  • Explanation: This error occurs when the specified checkpoint name does not match any files in the checkpoints directory.
  • Solution: Verify that the checkpoint file exists in the correct directory and that the name is spelled correctly. Ensure that the directory path is correctly set in the ComfyUI configuration.

Invalid checkpoint format

  • Explanation: This error indicates that the selected checkpoint file is not in a valid format or is corrupted.
  • Solution: Check the integrity of the checkpoint file and ensure it is in the correct format. If the file is corrupted, try re-downloading or re-saving the checkpoint.

Permission denied

  • Explanation: This error occurs when the node does not have the necessary permissions to access the checkpoint file.
  • Solution: Ensure that the file permissions are set correctly and that the ComfyUI process has the necessary read permissions for the checkpoints directory.
