LLaMA-Factory使用V100微调ChatGLM2报错 RuntimeError: “addmm_impl_cpu_“ not implemented for ‘Half‘

已经从huggingface下载完整的模型并配置正确路径，也对自定义数据集仿照alpaca_gpt4_data_zh.json在dataset_info.json中写入相关配置。但运行如上命令还是有报错如下：

命令运行过程中，看上去已经成功加载模型了，应该是训练第1个epoch时的报错。我--fp16加到上面的命令中运行，也有报错。

这是与开源社区交流的记录： https://github.com/hiyouga/LLaMA-Factory/issues/1359

• 原因：cuda 环境问题
• 解决方案：pip install torch==2.0.1
• 排查：打log看torch.cuda.is_available()输出为False说明CUDA环境有问题
