how to run internvl1.5-8bit with nvidia v100

[StevenBanama]

ERROR about flash_attr, can u help to provide version for these old nv card?

---

out, q, k, v, out_padded, softmax_lse, S_dmask, rng_state = flash_attn_cuda.fwd(
^^^^^^^^^^^^^^^^^^^^
RuntimeError: FlashAttention only supports Ampere GPUs or newer.

[StevenBanama]

same issue here: #65

it does not work; we meet the same error as #65; can you help to solve it?

• A common solution here.
• If you can understand Chinese, you can refer to this article
  • inference InternVL-1.5 by HF/LMDeploy/SWIFT on V100 GPUs.
  • test code: https://github.com/BIGBALLON/itvl1.5-v100-test

1. setup minimal env

conda create --name internvl python=3.10 -y
conda activate internvl
conda install pytorch==2.2.2 torchvision pytorch-cuda=11.8 -c pytorch -c nvidia -y
pip install transformers sentencepiece peft einops bitsandbytes accelerate timm ninja packaging protobuf 

2. change the model's cfg file (config.json)

• set use_flash_attn to false
• set attn_implementation to eager

3. prepare script

请详细描述图片 这张图片展示了一只金毛寻回犬幼犬坐在一片开满橙色花朵的草地上。幼犬的毛发是金黄色，看起来非常柔软和蓬松。它的眼睛是深色的，嘴巴张开，似乎在微笑或者是在喘气，显得非常活泼和快乐。背景是一片模糊的绿色草地，可能是由于使用了浅景深拍摄技术，使得焦点集中在幼犬身上，而背景则显得柔和模糊。整体上，这张图片传达了一种温馨和快乐的氛围，幼犬看起来非常健康和快乐。

This is a good solution, thanks for your answer!

hello, thanks for your script!
I'd wonder inference time when running on v100, cause I spend about 1 min per round on A100-40g. I don't know whether it's a normal speed or some bugs in my code [裂开]

[BIGBALLON]

@RAYRAYRAYRita I think it's normal. The specific time it takes depends on the text length you generate. The longer the answer you generate, the longer it takes. here is an article for speed test
