llama.cpp的examples里提供了一个finetune小工具,支持LoRA,这个工具比较简单,也不支持GPU加速,训练效率其实是比较差的,但对于我们学习来说,影响不大。 Chat-template 在开始之前,我们还需要对数据格式进行一点点微调: 匹配phi-3的chat-template:对于经过”指令微调“后的模型(我们用的phi-3-mini-4k-intruct就属于...
除此之外，这次还顺带发布了一个对齐人类偏好的finetune版本——Llama-2-chat模型，其对话流畅性和安全...

These options help improve the performance and memory usage of the LLaMA models. By adjusting these settings, you can fine-tune the model's behavior to better suit your system's capabilities and achieve optimal performance for your specific use case....

we'll take thellama.cpp toolas an example and introduce the detailed steps to quantize and deploy the model on MacOS and Linux systems. For Windows, you may need to install build tools like cmake.For a local quick deployment experience, it is recommended to use the instruction-finetuned ...
