🚀更新

模型链接	训练的数据量	模型版本	备注
https://huggingface.co/yuanzhoulvpi/chinese_bloom_7b_chat	15w中文指令数据	v1
https://huggingface.co/yuanzhoulvpi/chinese_bloom_7b_chat_v2	150w条中文指令数据	v2	目前已经测试过效果，相较于v1，效果有所提升
https://huggingface.co/yuanzhoulvpi/chinese_bloom_7b_chat_v3	420w条中文指令数据	v3	目前效果还没测试，欢迎大家测试

介绍

1. ✅ 对bloom-7b模型做了sft，本次版本为V2版本(使用了150w条有监督数据做sft)，相较于V1版本，效果更好！！！
2. 🚀 训练代码和推理代码全部分享，可以查看链接https://github.com/yuanzhoulvpi2017/zero_nlp/tree/main/chinese_bloom

如何使用

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(checkpoint).half().cuda()

        "Write a response that appropriately completes the request.\n\n"
        "### Instruction:\n{instruction}\n\n### Input:\n{input}\n\n### Response:"
    ),

        "Write a response that appropriately completes the request.\n\n"
        "### Instruction:\n{instruction}\n\n### Response:"
    ),
}
