TeaCache Issue After Update: Troubleshooting and Resolution

Introduction

The TeaCache is a crucial component in various machine learning models, particularly in the context of video processing and analysis. However, after a recent update, users have reported encountering issues with the TeaCache, specifically the "Prompt outputs failed validation" error. In this article, we will delve into the possible causes of this issue and provide step-by-step solutions to resolve the problem.

Understanding the Error Message

When encountering the "Prompt outputs failed validation" error, the error message typically includes the following details:

WanVideoTeaCache: This indicates that the issue is related to the TeaCache component in the WanVideo model.
Required input is missing: use_coefficients: This suggests that the use_coefficients input is missing, which is a required parameter for the TeaCache component.

Checking the Input Parameters

The first step in resolving this issue is to verify that the use_coefficients input is indeed missing. To do this:

Review the model architecture: Check the model architecture to ensure that the TeaCache component is properly configured and that the use_coefficients input is included.
Inspect the input parameters: Inspect the input parameters to confirm that the use_coefficients input is missing.
Check for typos or errors: Verify that there are no typos or errors in the input parameters, as this can cause the use_coefficients input to be missing.

Resolving the Issue

If the use_coefficients input is indeed missing, the following solutions can be applied:

Solution 1: Add the `use_coefficients` Input

To resolve the issue, add the use_coefficients input to the TeaCache component. This can be done by:

Modifying the model architecture: Update the model architecture to include the use_coefficients input.
Adding the input parameter: Add the use_coefficients input to the input parameters.

Solution 2: Update the Model Configuration

If the use_coefficients input is already included in the model architecture, the issue may be related to the model configuration. To resolve this:

Review the model configuration: Check the model configuration to ensure that the use_coefficients input is properly configured.
Update the model configuration: Update the model configuration to include the use_coefficients input.

Solution 3: Revert to a Previous Version

If the above solutions do not resolve the issue, it may be necessary to revert to a previous version of the model. This can be done by:

Checking the version history: Review the version history to identify the previous version that worked correctly.
Reverting to the previous version: Revert to the previous version of the model.

Conclusion

The "Prompt outputs failed validation" error with the TeaCache component can be a frustrating issue, especially after a recent update. By following the steps outlined in this article, users can troubleshoot and resolve the issue by adding the use_coefficients input, updating the model configuration, or reverting to a previous version of the model. By taking these steps, users can ensure that their TeaCache component is functioning correctly and that their machine learning models are running smoothly.
