Hello, may I ask the memory for your device? You can try to decrease prefill from 124928 to 122880 to see if it is still OOM. The code can run on a single A100-80GB.

What is your transformers version? Can you set it to transformers==4.37.2 since apply_rotary_pos_emb api changes for recent versions？

Jun 26 '24 02:06 preminstrel

thanks, I think it's more likely to be an environment problem

I changed the version of the transformer because there are other environment issues, such as:

Torch uses the default CUDA version (12.1), but mine is 11.8 (I installed it manually).
The latest flash-attn has this problem: https://github.com/Dao-AILab/flash-attention/issues/451, so I switched to an older version (2.5.2). If possible, could you please add a note in the README about the version of your flash_attn and how to install the correct version of torch?

Jun 26 '24 04:06 Lucas-TY

Yeah I am using CUDA 12.1. Here is my flash_attn version.

>>> import torch
>>> torch.__version__
'2.2.1+cu121'
>>> import flash_attn
>>> flash_attn.__version__
'2.5.7'

Jun 26 '24 04:06 preminstrel

I have added a FAQ in the README :)
