Executing bash train_1lm.sh resulted in an IndexError error: index -1 is out of bounds for dimension 0 with size 0

System Info

The environment is consistent with the default, and the GPU is Nvidia A40

Who can help?

No response

Information

• The official example scripts
• My own modified scripts

Tasks

• An officially supported task in the codebase (such as scrips/, ...)
• My own task or dataset (give details below)

Reproduction

From v4.47 onwards, when a model cache is to be returned, generate will return a Cache instance instead by default (as opposed to the legacy tuple of tuples format). If you want to keep returning the legacy format, please set return_legacy_cache=True.

last_step_score = step_score[-1]
IndexError: index -1 is out of bounds for dimension 0 with size 0

Expected behavior

How should I fix it, should I replace the A100 GPU or something? I can't simply check the length of the array and continue it
