介绍
✅ 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!!!
? 训练代码和推理代码全部分享,可以查看链接

如何使用

tokenizer = AutoTokenizer.from_pretrained(checkpoint)
model = AutoModelForCausalLM.from_pretrained(checkpoint).half().cuda()
PROMPT_DICT = {
"prompt_input": (
"Below is an instruction that describes a task, paired with an input that provides further context. "
"Write a response that appropriately completes the request.\n\n"

),
"prompt_no_input": (
"Below is an instruction that describes a task. "
"Write a response that appropriately completes the request.\n\n"

}
from typing import Optional
