ComfyUI Node: LatentStorageReset

LatentStorageReset:

The LatentStorageReset node is designed to clear specific entries or all entries from the global latent storage. This node is particularly useful when you need to manage and reset the latent data stored during various stages of your AI art generation pipeline. By providing a mechanism to selectively delete latent data, it helps in maintaining an organized and efficient workflow, ensuring that outdated or unnecessary data does not clutter the storage. This node is essential for workflows that involve iterative processes or loops, where latent data might accumulate over time and need periodic clearing to avoid memory issues or to start fresh with new data.

LatentStorageReset Input Parameters:

key_list

The key_list parameter specifies which keys in the global latent storage should be reset. It accepts a string input, which can be a single key or a comma-separated list of keys. If you want to reset all keys, you can use the default value *. This parameter allows you to control precisely which latent data entries are deleted, providing flexibility in managing your storage. The key_list can be multiline, making it easier to input multiple keys if needed.

pipeline

The pipeline parameter is optional and accepts a LOOPCHAIN_PIPELINE type. This parameter can be used to specify a particular pipeline context in which the reset operation should be performed. It allows for more advanced configurations where the latent storage reset is part of a larger, more complex pipeline.

LatentStorageReset Output Parameters:

None

This node does not produce any output parameters. Its primary function is to perform an action (resetting latent storage) rather than generating data to be passed to subsequent nodes.

LatentStorageReset Usage Tips:

• Use the key_list parameter to selectively clear specific latent data entries, which can help in managing memory usage and ensuring that only relevant data is retained.
• Utilize the default value * for key_list when you need to clear all entries in the global latent storage, especially useful at the beginning or end of a pipeline to ensure a clean state.
• Consider using the pipeline parameter if you are working within a complex pipeline and need to reset latent storage in a specific context.

LatentStorageReset Common Errors and Solutions:

KeyError: 'key'

• Explanation: This error occurs when the specified key in the key_list does not exist in the global latent storage.
• Solution: Ensure that the keys you provide in the key_list are correct and exist in the global latent storage. You can check the available keys before executing the reset.

TypeError: 'NoneType' object is not iterable

• Explanation: This error might occur if the key_list is not properly formatted or if there is an issue with the input type.
• Solution: Verify that the key_list is a properly formatted string and that it adheres to the expected input format. Ensure that the input is not None.

AssertionError: Latent storage key doesn't exist

• Explanation: This error is raised when attempting to delete a key that is not present in the global latent storage.
• Solution: Double-check the keys provided in the key_list to ensure they are valid and exist in the storage. If you are unsure, you can list the current keys in the storage before performing the reset operation.
