Performance mismatch

[wtzhang99]

Hi, I ran ChartQA-Test evaluation on OPPOer/AndesVL-0_6B-Instruct with provided code with provided package version And

CUDA=13.0
flash_attn=2.8.3

The performance i got is

--------------  -----
test_human      54.8
test_augmented  85.76
Overall         **70.28**
--------------  -----

While the number reported in the paper is 78.2.

Is there any special specification to reproduce this result ?

Thx !
