Token length limit

[rose-jinyang]

Hello
How are you?
Thanks for contributing to this project.
I am going to fine-tune Whisper model for Indian Telugu language on google/fleurs dataset.

torchrun --nproc_per_node=2 finetune.py --base_model=openai/whisper-large-v2 --language=None

But while training, I met the following issue.

File "/opt/conda/lib/python3.10/site-packages/transformers/models/whisper/modeling_whisper.py", line 1757, in forward
raise ValueError(
ValueError: Labels' sequence length 495 cannot exceed the maximum allowed length of 448 tokens.

What do you think about possible reasons?
