在interStudio进行InternLM2-Chat-1.8B模型访问,进入开发机后
- 配置基础环境
新建conda环境并且进入
conda create -n demo python3.10 -y
conda activate demo
下载pytorch等相关包
conda install pytorch2.0.1 torchvision0.15.2 torchaudio2.0.2 pytorch-cuda=11.7 -c pytorch -c nvidia
pip install huggingface-hub0.17.3
pip install transformers4.34
pip install psutil5.9.8
pip install accelerate0.24.1
pip install streamlit1.32.2
pip install matplotlib3.8.3
pip install modelscope1.9.5
pip install sentencepiece0.1.99
- 创建下载模型的文件,并下载模型
import os
from modelscope.hub.snapshot_download import snapshot_download
# 创建保存模型目录
os.system("mkdir /root/models")
# save_dir是模型保存到本地的目录
save_dir="/root/models"
snapshot_download("Shanghai_AI_Laboratory/internlm2-chat-1_8b",
cache_dir=save_dir,
revision='v1.1.0')
- 创建执行文件

tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, trust_remote_code=True, device_map='cuda:0')
model = AutoModelForCausalLM.from_pretrained(model_name_or_path, trust_remote_code=True, torch_dtype=torch.bfloat16, device_map='cuda:0')
model = model.eval()

messages = [(system_prompt, '')]
print("=============Welcome to InternLM chatbot, type 'exit' to exit.=============")
while True:
input_text = input("\nUser >>> ")
input_text = input_text.replace(' ', '')
if input_text == "exit":
break
length = 0
for response, _ in model.stream_chat(tokenizer, input_text, messages):
if response is not None:
print(response[length:], flush=True, end="")
length = len(response)
- 测试模型demo
点评:能创作通话故事,但是故事主角有3个而不是2个,缺失了人物主角。
不知道是对齐的时候太严格了还是怎么样,能力有限
