Inference String Format

The inference string is a concatenated string formed by combining conversation data(system, human and bot contents) in the training data format. It is used as input during the inference process. Here is an example format of the concatenated string:

"""
<s>system
System instruction
<s>human
Human 1st round input
<s>bot
Bot 1st round output<|endoftext|>
<s>human
Human 2nd round input
<s>bot
Bot 2nd round output<|endoftext|>
...
...
...
<s>human
Human nth round input
<s>bot
{Bot output to be genreated}<|endoftext|>
"""

When applying inference, you always make your input string end with "<s>bot" to ask the model generating answers.

  • CUDA 11.4

推理数据格式

推理数据为模型在训练数据格式下拼接的字符串形式,它也是推理时输入prompt拼接的方式:

"""
<s>system
这是System指令
<s>human
这是第1轮用户输入的问题
<s>bot
这是第1轮模型生成的内容<|endoftext|>
<s>human
这是第2轮用户输入的问题
<s>bot
这是第2轮模型生成的内容<|endoftext|>
...
...
...
<s>human
这是第n轮用户输入的问题
<s>bot
{模型现在要生成的内容}<|endoftext|>
"""

推理时,请确保拼接的prompt字符串以"<s>bot\n"结尾,引导模型生成回答。
