extent analysis

TL;DR

The error is likely caused by an "IndexError: list index out of range" exception in the slice_lora_b function, which may be due to incorrect Lora configuration or model loading.

Guidance

  • Check the Lora configuration and model loading process to ensure that the lora_b list is properly initialized and indexed.
  • Verify that the mix-lora=checkpoint configuration is correct and compatible with the model being used.
  • Review the model architecture and Lora implementation to ensure that the slice_lora_b function is correctly handling the Lora weights.
  • Consider checking the model's documentation or seeking help from the model's developers to ensure proper usage of Lora.

Notes

The error message indicates that the issue is related to the Lora configuration or model loading, but the exact cause is unclear without further information about the model and its implementation.

Recommendation

Apply a workaround by re-checking the Lora configuration and model loading process to ensure correctness, and consider seeking help from the model's developers if necessary.
