llamafactory微调模型报错ModuleNotFoundError: No module named ‘triton.ops‘

一、问题

在阿里云Notebook上使用llamafactory微调Meta-Llama-3-8B-Instruct模型报错ModuleNotFoundError: No module named ‘triton.ops’

Traceback (most recent call last):

二、原因

在triton新版本中，triton.ops不存在了，可在triton的github上找到对应问题：
In version 3.2.0 of triton, triton.ops no longer exists (triton-lang/triton#5471)
from: https://github.com/edenartlab/sd-lora-trainer/issues/12

二、问题解决

参考github上Import error with latest version of triton #12
给出的解决方案，调整triton为旧版本

查看triton的版本(https://github.com/triton-lang/triton/blob/main/RELEASE.md)如下：

这里选择旧一点的版本: 2.3.0

pip uninstall triton
pip install triton==2.3.0

重新启动llamafactory-cli webui，进行微调，可正常运行：
