设置packing=True SFTTrainer 使用prompt拼接如下: def formatting_func(example): text = f"### Question: {example['question']}\n ### Answer: {example['answer']}" return text trainer = SFTTrainer( "facebook/opt-350m", train_dataset=dataset, packing=True, formatting_func=formatting_func )...
sfttrainer参数packing是一种用于优化深度学习模型训练的技术。在神经网络模型训练中,参数packing指的是将多个权重参数打包成更少的数据单元进行存储和传输。通过将多个参数合并为一个数据单元,可以减少内存占用和数据传输的开销。 以sfttrainer为例,它是一种用于语义分割任务的训练器。在语义分割任务中,需要处理大量的图像...
This is a common format for instruction tuning models. In principle it can be any function that takes a row of your dataset and returns a text field. This function is applied to the whole dataset then. Note that since this is language modeling, there are no input output pairs but the wh...

2.packing模式下的loss问题 构造SFT数据的方式有两种:padding(填充)和packing(打包) 样本构造示意图 如果以一个样本作为训练单位,那么剩余空间需要用pad占位,而在指令数据当中短文本是占比很大的,这样会造成浪费,导致训练效率低下,于是就有将若干sample打包在一起的训练的做法。
