Nvidia V100 GPU 运行 InternVL 1.5-8bit

        InternVL        运行 InternVL 1.5-8bit教程

        InternVL        官网仓库及教程

1. 设置最小环境

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.更改模型的cfg文件（config.json）

        OpenGVLab/InternVL-Chat-V1-5-Int8       里面包含了config.json文件

• 设置use_flash_attn​false
• 设置attn_implementation​eager

3.准备脚本        inter.py

4.检查结果

FlashAttention is not installed.
The `load_in_4bit` and `load_in_8bit` arguments are deprecated and will be removed in the future versions. Please, pass a `BitsAndBytesConfig` object in `quantization_config` argument instead.
Unused kwargs: ['quant_method']. These kwargs are not used in <class 'transformers.utils.quantization_config.BitsAndBytesConfig'>.

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。
