Automatically generates checkpoints during the execution of workflows in ComfyUI, enabling users to resume processes with minimal data loss in case of interruptions like crashes or cancellations. This tool is essential for maintaining workflow continuity and efficiency, particularly in long-running tasks.
- Enables automatic checkpoint creation, ensuring progress is saved throughout workflow execution.
- Supports both local and networked checkpoint storage, providing flexibility based on user needs.
- Allows for independent execution caching for multiple users through client ID management.
Context
This tool, ComfyUI-WorkflowCheckpointing, is designed to enhance the functionality of ComfyUI by automatically creating checkpoints during the execution of workflows. Its primary purpose is to mitigate the risks associated with workflow interruptions, such as crashes or user cancellations, by allowing users to resume workflows without significant loss of progress.
Key Features & Benefits
The main feature of this tool is its ability to create checkpoints automatically, which ensures that if a workflow is interrupted, users can quickly resume from the last saved point. It also allows for configurations that enable storage of checkpoints either locally or on a network via the Salad Simple Storage Service, giving users the option to choose the most suitable storage method for their needs.
Advanced Functionalities
For advanced users, the tool offers a feature that allows the simulation of workflow crashes for testing purposes. By setting the FORCE_CRASH_AT variable, users can specify a particular sampling step at which the workflow execution will terminate, facilitating the assessment of the checkpointing functionality under controlled conditions.
Practical Benefits
This tool significantly enhances workflow management in ComfyUI by providing a safety net against data loss, thus improving overall efficiency and control. Users can focus on their creative processes without the constant worry of losing progress, making it an invaluable addition for those working on complex or lengthy tasks.
