| 基于langchain和chatGML的LLM文档阅读器 |
| |
| options: |
| -h, --help show this help message and exit |
| --no-remote-model remote in the model on loader checkpoint, if your load local model to add the ` --no-remote-model` |
| --model MODEL Name of the model to load by default. |
| --lora LORA Name of the LoRA to apply to the model by default. |
| --model-dir MODEL_DIR |
| Path to directory with all the models |
| --lora-dir LORA_DIR Path to directory with all the loras |
| --cpu Use the CPU to generate text. Warning: Training on CPU is extremely slow. |
| --auto-devices Automatically split the model across the available GPU(s) and CPU. |
| --gpu-memory GPU_MEMORY [GPU_MEMORY ...] |
| Maxmimum GPU memory in GiB to be allocated per GPU. Example: --gpu-memory 10 for a single GPU, --gpu-memory 10 5 for two GPUs. You can also set values in MiB like --gpu-memory 3500MiB. |
| --cpu-memory CPU_MEMORY |
| Maximum CPU memory in GiB to allocate for offloaded weights. Same as above. |
| --load-in-8bit Load the model with 8-bit precision. |
| --bf16 Load the model with bfloat16 precision. Requires NVIDIA Ampere GPU. |

| #### 示例 |
|
|
| - 1、加载本地模型 |
|
|
| ```text |
| --model-dir 本地checkpoint存放文件夹 |
| --model 模型名称 |
| --no-remote-model 不从远程加载模型 |
| ``` |
| ```shell |
| $ python cli_demo.py --model-dir /media/mnt/ --model chatglm-6b --no-remote-model |
| ``` |
|
|
| - 2、低精度加载模型 |
| ```text |
| --model-dir 本地checkpoint存放文件夹 |
| --model 模型名称 |
| --no-remote-model 不从远程加载模型 |
| --load-in-8bit 以8位精度加载模型 |
| ``` |
| ```shell |
| $ python cli_demo.py --model-dir /media/mnt/ --model chatglm-6b --no-remote-model --load-in-8bit |
| ``` |
|
|
|
|
| - 3、使用cpu预测模型 |
| ```text |
| --model-dir 本地checkpoint存放文件夹 |
| --model 模型名称 |
| --no-remote-model 不从远程加载模型 |
| --cpu 使用CPU生成文本。警告:CPU上的训练非常缓慢。 |
| ``` |
| ```shell |
| $ python cli_demo.py --model-dir /media/mnt/ --model chatglm-6b --no-remote-model --cpu |
| ``` |
|
|
|
|
|
|
| - 3、加载lora微调文件 |
| ```text |
| --model-dir 本地checkpoint存放文件夹 |
| --model 模型名称 |
| --no-remote-model 不从远程加载模型 |
| --lora-dir 本地lora存放文件夹 |
| --lora lora名称 |
| ``` |
| ```shell |
| $ python cli_demo.py --model-dir /media/mnt/ --model chatglm-6b --no-remote-model --lora-dir /media/mnt/loras --lora chatglm-step100 |
| ``` |
