# LLaMA-Factory Kernels 系统
|
||||
|
||||
## 概述
|
||||
|
||||
LLaMA-Factory Kernels 系统用于管理不同硬件设备提供的高性能计算内核(kernel)实现,该系统通过替换模型中的关键模块(如 RMSNorm、SwiGLU、RoPE、MoE 等)为硬件优化的版本,从而显著提升模型训练和推理的性能。
|
||||
|
||||
Kernels 系统采用基于注册表的自动发现机制,能够根据当前运行环境自动检测可用的硬件设备(NPU、CUDA 等),并使能相应的高性能 kernels。这种设计使得用户无需关心底层实现细节,只需简单调用接口即可获得性能提升。
|
||||
|
||||
## 核心特性
|
||||
|
||||
- **自动注册机制**:基于 `@register_kernel` 装饰器实现自动注册系统。系统启动时会自动扫描 `ops` 目录下的 kernel 实现,并将其注册到全局注册表中。
|
||||
|
||||
- **设备适配感知**:自动检测当前硬件设备(NPU、CUDA 等)并应用相应的优化。系统会跳过不支持的设备,确保在不同环境下都能正常工作。
|
||||
|
||||
- **模块化设计**:每个 kernel 独立实现,互不干扰。可以单独应用某个 kernel,也可以批量应用所有默认的 kernels。
|
||||
|
||||
- **后向兼容**:kernel 替换不修改模型权重,保持数值一致性。优化后的实现与原始实现保持精度一致(在浮点误差范围内)。
|
||||
|
||||
- **灵活扩展**:通过继承 `BaseKernel` 基类并使用装饰器,可以轻松添加新的 kernel 实现,支持新的硬件设备或优化算法。
|
||||
|
||||
## 使用方式
|
||||
|
||||
### 1. 通过训练 YAML 配置文件使用
|
||||
|
||||
要在训练过程中使能 kernels,只需在配置文件中增加如下配置,即可自动使能所有默认可用的 kernels:
|
||||
|
||||
```yaml
|
||||
...
|
||||
kernel_config:
|
||||
name: auto
|
||||
include_kernels: auto # choice: null/true/false/auto/kernel_id1,kernel_id2,kernel_id3, default is null
|
||||
|
||||
...
|
||||
```
|
||||
|
||||
### 2. 调用 API 使能
|
||||
|
||||
#### 2.1 apply_default_kernels 使能所有默认 kernels
|
||||
|
||||
`apply_default_kernels` API 能够自动应用当前设备上所有默认注册的 kernels:
|
||||
|
||||
```python
|
||||
from transformers import AutoModelForCausalLM
|
||||
from llamafactory.v1.plugins.model_plugins.kernels import apply_default_kernels
|
||||
|
||||
# 加载模型
|
||||
model = AutoModelForCausalLM.from_pretrained("qwen/qwen2.5-0.5B")
|
||||
|
||||
# 自动应用所有默认 kernels
|
||||
model = apply_default_kernels(model, include_kernels="auto")
|
||||
```
|
||||
|
||||
#### 2.2 apply_kernel 使能特定 kernel
|
||||
|
||||
如果需要更精细的控制,例如在某些场合单独应用某个 kernel,可以手动调用 `apply_kernel` 函数并传入 kernel ID:
|
||||
|
||||
```python
|
||||
from transformers import AutoModelForCausalLM
|
||||
from llamafactory.v1.plugins.model_plugins.kernels import apply_kernel
|
||||
|
||||
# 加载模型
|
||||
model = AutoModelForCausalLM.from_pretrained("qwen/qwen2.5-0.5B")
|
||||
|
||||
# 手动应用各个 kernels
|
||||
# 注意:kernel ID 必须与定义时的 _kernel_id 一致
|
||||
model = apply_kernel("npu_fused_rope", model=model)
|
||||
model = apply_kernel("npu_fused_rmsnorm", model=model)
|
||||
model = apply_kernel("npu_fused_swiglu", model=model)
|
||||
model = apply_kernel("npu_fused_moe", model=model)
|
||||
|
||||
### 3. 查询已注册的可用 kernels
|
||||
|
||||
可以通过 `get_default_kernels` 获取当前环境中所有已注册且可用的默认 kernel ID:
|
||||
|
||||
```python
|
||||
from llamafactory.v1.plugins.model_plugins.kernels import get_default_kernels
|
||||
|
||||
# 获取默认 kernel 列表
|
||||
available_kernels = get_default_kernels()
|
||||
print(f"Available kernels: {available_kernels}")
|
||||
# 输出示例: ['npu_fused_rmsnorm', 'npu_fused_swiglu', 'npu_fused_rope', 'npu_fused_moe']
|
||||
```
|
||||
|
||||
### 当前已实现的 kernels
|
||||
|
||||

# Fused Operators
|
||||
|
||||
LLaMA-Factory 提供了一系列针对特定硬件优化的融合算子。这些算子位于 `src/llamafactory/v1/plugins/model_plugins/kernels/ops` 目录下。
|
||||
|
||||
系统启动时,`scan_all_kernels` 函数会自动扫描该目录,注册所有可用的算子。您可以通过 `apply_default_kernels(model, include_kernels="auto")` 一键启用它们,或者使用 `apply_kernel` 单独启用。
|
||||
|
||||
以下是当前支持的融合算子详情:
|
||||
|
||||
## NpuFusedRMSNorm
|
||||
RMSNorm(Root Mean Square Layer Normalization)是一种常用于大模型的归一化方法。在推理或训练中,RMSNorm 融合算子 将bias、residual等操作进行融合,可以减少显存访问次数,加速计算。
|
||||
|
||||
Ascend npu 通过 `torch_npu.npu_rms_norm` 接口提供 RMSNorm 融合算子调用接口,支持 float16, bfloat16, float 等数据格式。RMSNorm 算子常见于Qwen等LLM模型中,由于torch侧没有提供 RMSNorm 算子的接口,因此在模型中通常是以自定义类的形式出现,通过替换 RMSNorm 类的 `forward` 方法即可使能。
|
||||
|
||||
```python
|
||||
def _npu_rms_forward(self, hidden_states):
|
||||
"""NPU forward implementation for RMSNorm.
|
||||
|
||||
Args:
|
||||
self: RMSNorm module instance with `weight` and `variance_epsilon`.
|
||||
hidden_states: Input hidden states tensor, same shape as the baseline.
|
||||
|
||||
Returns:
|
||||
Normalized tensor consistent with the baseline RMSNorm behavior.
|
||||
"""
|
||||
|
||||
return torch_npu.npu_rms_norm(hidden_states, self.weight, epsilon=self.variance_epsilon)[0]
|
||||
```
|
||||
|
||||
在 LlamaFactory 中,通过 `NpuRMSNormKernel` 提供使能该融合算子的入口,只需要调用 `apply_kernel("npu_fused_rmsnorm", model=model)` 即可针对已适配的模型使能 npu RMSNorm 融合算子。
|
||||
|
||||
## NpuFusedSwiGlu
|
||||
SwiGLU(Swish-Gated Linear Unit)是一种结合了Swish激活函数和门控线性单元(GLU)的混合激活函数,其主要功能是对输入张量进行门控线性变换,近年来被广泛应用于 LLM 模型中的 MLP 层。SwiGLU 融合算子将分割、激活、矩阵乘等多个操作融合为单一硬件指令,避免多次内核启动开销。
|
||||
|
||||
Ascend npu 通过 `torch_npu.npu_swiglu` 接口提供 SwiGLU 融合算子调用接口,支持 float16,bfloat16,float SwiGLU 算子常见于Qwen等LLM模型中,由于torch侧没有提供 SwiGLU 算子的接口,因此在模型中通常是以自定义类的形式出现,通过替换 SwiGLU 类的 `forward` 方法即可使能。替换过程可参考如下示例:
|
||||
|
||||
```python
|
||||
# 原始 MLP forward 方法:
|
||||
def forward(self, x):
|
||||
down_proj = self.down_proj(self.act_fn(self.gate_proj(x)) * self.up_proj(x))
|
||||
return down_proj
|
||||
|
||||
# 替换后的 forward 方法:
|
||||
def _npu_swiglu_forward(self, hidden_state):
|
||||
return self.down_proj(
|
||||
torch_npu.npu_swiglu(torch.cat((self.gate_proj(hidden_state), self.up_proj(hidden_state)), dim=-1), dim=-1)
|
||||
)
|
||||
```
|
||||
|
||||
在 LLaMA-Factory 中,通过 `NpuSwiGluKernel` 提供使能该融合算子的入口,只需要调用 `apply_kernel("npu_fused_swiglu", model=model)` 即可针对已适配的模型使能 npu SwiGLU 融合算子。对于未适配的模型,如有需要,您可根据示例以及[开发者文档](../../dev-guide/plugins/model-plugins/kernels.md)自行适配。
|
||||
|
||||
|
||||
## NpuFusedRoPE
|
||||
RoPE(Rotary Positional Embedding,旋转式位置嵌入) 是一种位置编码技术,广泛应用于 Qwen 等 LLM 模型中,用于有效编码文本序列的位置信息。它结合了绝对位置编码的稳定性与相对位置编码的灵活性,同时具备优秀的长度泛化能力。传统 RoPE 算子通常在 LLM 等模型结构中通过自定义函数的形式实现。RoPE 融合算子将原计算流程合并为单个硬件优化算子,从而提升性能。
|
||||
|
||||
Ascend npu 通过 `torch_npu.npu_rotary_mul` 提供 RoPE 融合算子调用接口,支持 float16,bfloat16,float32 等数据格式。以 Qwen3 系列模型为例,通过替换其 `apply_rotary_pos_emb` 函数即可实现 RoPE融合算子使能:
|
||||
|
||||
```python
|
||||
# 原始 apply_rotary_pos_emb:
|
||||
def apply_rotary_pos_emb(q, k, cos, sin, position_ids=None, unsqueeze_dim=1):
|
||||
cos = cos.unsqueeze(unsqueeze_dim)
|
||||
sin = sin.unsqueeze(unsqueeze_dim)
|
||||
q_embed = (q * cos) + (rotate_half(q) * sin)
|
||||
k_embed = (k * cos) + (rotate_half(k) * sin)
|
||||
return q_embed, k_embed
|
||||
|
||||
# 替换 RoPE 融合算子后:
|
||||
def _apply_rotary_pos_emb(q, k, cos, sin, position_ids=None, unsqueeze_dim=1):
|
||||
cos = cos.unsqueeze(unsqueeze_dim)
|
||||
sin = sin.unsqueeze(unsqueeze_dim)
|
||||
q_embed = torch_npu.npu_rotary_mul(q, cos, sin)
|
||||
k_embed = torch_npu.npu_rotary_mul(k, cos, sin)
|
||||
return q_embed, k_embed
|
||||
```
|
||||
|
||||
在 LLaMA-Factory 中,通过 `NpuRoPEKernel` 提供使能该融合算子的入口,只需要调用 `apply_kernel("npu_fused_rope", model=model)` 即可针对已适配的模型使能 npu RoPE 融合算子。对于未适配的模型,如有需要,您可根据示例以及[开发者文档](../../dev-guide/plugins/model-plugins/kernels.md)自行适配。
|
||||
|
||||
|
||||
## NpuFusedMoE
|
||||
MoE(Mixture of Experts)模型通过稀疏激活扩展容量。在原生 Transformers 实现中,使用串行循环遍历专家,导致内核启动开销大、硬件利用率低。
|
||||
|
||||
**MoE 融合算子** 利用 **GMM(Grouped Matrix Multiplication,分组矩阵乘)** 技术,支持在单个硬件指令内并行处理多组不同形状(行数不一)的矩阵乘法,消减循环开销,同时无需额外的显存复制,显著提升训练性能。
|
||||
|
||||
Ascend npu 通过 `torch_npu.npu_grouped_matmul` 等接口提供底层支持,通过替换模型中的 MoE Block forward 方法,即可利用 NPU 的分组矩阵乘能力。
|
||||
|
||||
核心逻辑替换如下(简化示意):
|
||||
|
||||
```python
|
||||
def _npu_moe_forward(self, hidden_states, routing_weights, router_indices):
|
||||
# 1. 排序:将乱序的 Token 按指派的专家归类,并生成索引映射
|
||||
permuted_states, row_map = torch_npu.npu_moe_token_permute(hidden_states, router_indices)
|
||||
|
||||
# 2. 统计:计算每个专家需要处理的 Token 数量
|
||||
tokens_per_expert = torch.histc(router_indices, bins=self.num_experts, min=0, max=self.num_experts)
|
||||
|
||||
# 3. 计算 (GMM):一次性并行计算所有专家的权重,自动适配不同专家的输入长度
|
||||
inter_states = torch_npu.npu_grouped_matmul(permuted_states, self.gate_up_proj_weights, split_sizes=tokens_per_expert, ...)
|
||||
inter_states = torch_npu.npu_swiglu(inter_states)
|
||||
output = torch_npu.npu_grouped_matmul(inter_states, self.down_proj_weights, split_sizes=tokens_per_expert, ...)
|
||||
|
||||
# 4. 还原:将结果恢复成原始 Token 顺序并应用路由权重
|
||||
return torch_npu.npu_moe_token_unpermute(output, row_map, routing_weights)
|
||||
```
|
||||
|
||||
在 LLaMA-Factory 中,通过 `NpuFusedMoEKernel` 提供使能该融合算子的入口。只需要调用 `apply_kernel("npu_fused_moe", model=model)` 即可针对已适配的模型使能 NPU MoE 融合算子。对于未适配的模型,您也可以参考上述示例代码以及[开发者文档](../../dev-guide/plugins/model-plugins/kernels.md)自行适配。

<details open>
|
||||
<summary>方式 1:使用 HF Hub Repo ID</summary>
|
||||
|
||||
直接指定 HF Hub 上的数据集 Repo ID,DataEngine 会自动从 HF Hub 下载并加载数据集。
|
||||
|
||||
注:使用 Repo ID 直接加载的数据集需要为标准格式
|
||||
|
||||
**训练配置文件示例:**
|
||||
|
||||
```yaml
|
||||
# example_sft.yaml
|
||||
|
||||
...
|
||||
|
||||
dataset: llamafactory/v1-sft-demo # HF Hub Repo ID
|
||||
|
||||
...
|
||||
```

<summary>方式 2:使用 HF Hub 上的 YAML 配置文件</summary>
|
||||
|
||||
`dataset`字段指定 HF Hub 上的 `dataset_info.yaml` 的 URI,DataEngine 会自动下载该配置文件并根据其中的配置加载数据集。
|
||||
|
||||
**训练配置文件示例:**
|
||||
|
||||
```yaml
|
||||
# example_sft.yaml
|
||||
|
||||
...
|
||||
|
||||
dataset: llamafactory/v1-sft-demo/dataset_info.yaml # 远程 dataset_info.yaml 路径
|
||||
|
||||
...
|
||||
|
||||
```
|
||||
|
||||
</details>
|
||||
|
||||
<details>
|
||||
<summary>方式 3:使用本地 HF 数据集文件路径</summary>
|
||||
|
||||
`dataset`字段指定本地的数据集文件路径(`.json`、`.jsonl` 等)
|
||||
|
||||
注:直接指定数据集文件路径,要求该数据文件的格式已为标准格式
|
||||
|
||||
**训练配置文件示例:**
|
||||
|
||||
```yaml
|
||||
# example_sft.yaml
|
||||
|
||||
...
|
||||
|
||||
dataset: ~/data/v1_sft_demo.jsonl # 本地数据集文件绝对路径
|
||||
|
||||
...
|
||||
```
|
||||
|
||||
</details>
|
||||
|
||||
<details>
|
||||
<summary>方式 4:使用本地 YAML 配置文件路径</summary>
|
||||
|
||||
`dataset`字段指定本地的 `dataset_info.yaml` 配置文件路径,DataEngine 会根据该配置加载其中的数据集。
|
||||
|
||||
**训练配置文件示例:**
|
||||
|
||||
```yaml
|
||||
# example_sft.yaml
|
||||
|
||||
...
|
||||
|
||||
dataset: ~/data/dataset_info.yaml # 本地 dataset_info.yaml 文件路径
|
||||
|
||||
...
|
||||
```
|
||||
|

|
||||
|
||||
|
||||
|
||||
## 标准数据格式
|
||||
|
||||
v1 使用统一的 **Messages 格式**作为标准数据格式。每个样本都是一个包含 `messages` 字段的 JSON 对象。
|
||||
|
||||
针对alpaca、sharegpt、以及dpo等格式的数据,可以通过内置的`DataConverterPlugin`插件,自动将其转化为标准格式,对于其他自定义格式的数据,用户也可通过自定义`DataConverterPlugin`来实现数据格式标准化,这部分内容参见[`DataConverterPlugin`](../dev-guide/plugins/data-plugins.md/#data-converter-plugin)
|
||||
|
||||
### 1. SFT(监督微调)样本格式
|
||||
|
||||
|
||||
```json
|
||||
{
|
||||
"messages": [
|
||||
{
|
||||
"role": "system",
|
||||
"content": [{"type": "text", "value": "You are a helpful assistant."}],
|
||||
"loss_weight": 0.0
|
||||
},
|
||||
{
|
||||
"role": "user",
|
||||
"content": [{"type": "text", "value": "Hello, who are you?"}],
|
||||
"loss_weight": 0.0
|
||||
},
|
||||
{
|
||||
"role": "assistant",
|
||||
"content": [{"type": "text", "value": "I am an AI assistant."}],
|
||||
"loss_weight": 1.0
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
#### 字段说明:
|
||||
|
||||
- **messages**: 消息列表,包含一轮或多轮对话
|
||||
- **role**: 消息角色,可选值:
|
||||
- `"system"`: 系统提示
|
||||
- `"user"`: 用户输入
|
||||
- `"assistant"`: 模型回复
|
||||
- **content**: 内容列表,每个元素包含:
|
||||
- **type**: 内容类型,可选值:
|
||||
- `"text"`: 文本内容
|
||||
- `"image_url"`: 图像 URL(多模态)
|
||||
- `"audio_url"`: 音频 URL(多模态)
|
||||
- `"video_url"`: 视频 URL(多模态)
|
||||
- `"tools"`: 工具描述
|
||||
- `"tool_calls"`: 工具调用
|
||||
- `"reasoning"`: 推理过程
|
||||
- **value**: 具体内容(字符串)
|
||||
- **loss_weight**: 损失权重(浮点数)
|
||||
- `0.0`: 不计算损失(用于提示词部分)
|
||||
- `1.0`: 完全计算损失(用于回复部分)
|
||||
- 可设置为其他值以调整不同部分的学习权重
|
||||
|
||||
- **_dataset_name** (可选): 数据集名称,由 DataEngine 自动添加
|
||||
- **extra_info** (可选): 额外信息字段
|
||||
|
||||
### 2. DPO(偏好对齐)样本格式
|
||||
|
||||
```json
|
||||
{
|
||||
"chosen_messages": [
|
||||
{
|
||||
"role": "user",
|
||||
"content": [{"type": "text", "value": "用户提问"}],
|
||||
"loss_weight": 0.0
|
||||
},
|
||||
{
|
||||
"role": "assistant",
|
||||
"content": [{"type": "text", "value": "更优的回答"}],
|
||||
"loss_weight": 1.0
|
||||
}
|
||||
],
|
||||
"rejected_messages": [
|
||||
{
|
||||
"role": "user",
|
||||
"content": [{"type": "text", "value": "用户提问"}],
|
||||
"loss_weight": 0.0
|
||||
},
|
||||
{
|
||||
"role": "assistant",
|
||||
"content": [{"type": "text", "value": "较差的回答"}],
|
||||
"loss_weight": 1.0
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 多模态支持
|
||||
|
||||
对于多模态数据,可以在 `content` 列表中添加非文本类型的内容:
|
||||
|
||||
```json
|
||||
{
|
||||
"messages": [
|
||||
{
|
||||
"role": "user",
|
||||
"content": [
|
||||
{"type": "text", "value": "这张图片里有什么?"},
|
||||
{"type": "image_url", "value": "path/to/image.jpg"}
|
||||
],
|
||||
"loss_weight": 0.0
|
||||
},
|
||||
{
|
||||
"role": "assistant",
|
||||
"content": [{"type": "text", "value": "图片中有一只猫。"}],
|
||||
"loss_weight": 1.0
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**说明**:`image_url`、`audio_url`、`video_url` 的路径可以是相对路径或绝对路径,具体加载方式由 `DataLoaderPlugin` 决定。
|
||||
|
||||
---
|
||||
|
||||
## 数据集配置文件
|
||||
|
||||
### 1. dataset_info.yaml 配置文件格式
|
||||
|
||||
`dataset_info.yaml` 支持同时配置多个数据集,支持分别从 HF Hub 和本地获取数据集,数据集默认会混合并打乱顺序。
|
||||
|
||||
**示例配置文件:`data/dataset_info.yaml`**
|
||||
|
||||
```yaml
|
||||
# 数据集 1:使用本地文件 + Alpaca 转换器
|
||||
identity:
|
||||
file_name: ~/data/identity.json #本地数据集文件绝对路径
|
||||
converter: alpaca # 使用 alpaca 转换器
|
||||
|
||||
# 数据集 2:指定自定义数据集目录
|
||||
alpaca_en_demo:
|
||||
file_name: ~/data/alpaca_en_demo.json # 数据集文件名
|
||||
converter: alpaca # 转换器插件
|
||||
size: 500 # 只使用 500 个样本
|
||||
weight: 0.5 # 数据集权重,用于控制该数据集的采样频率
|
||||
split: train # 数据集划分,默认为 train
|
||||
streaming: false # 是否流式加载,默认为 false
|
||||
|
||||
# 数据集 3:从 Hugging Face Hub 加载
|
||||
hf_dataset:
|
||||
hf_hub_url: llamafactory/v1-sft-demo # HF repo ID
|
||||
streaming: false
|
||||
|
||||
# 数据集 4:已经是标准格式,无需转换器
|
||||
standard:
|
||||
file_name: ~/data/v1_sft_demo.jsonl # 本地标准数据集文件路径
|
||||
|
||||
# 数据集 5:自定义数据集和 converter 插件
|
||||
custom_dataset:
|
||||
file_name: custom_data.json
|
||||
converter: custom_converter
|
||||
weight: 1.0
|
||||
```
|
||||
|
||||
### 2. 配置字段说明

|
||||
|
||||
data_args = DataArguments(dataset="data/multimodal_demo.jsonl")
|
||||
engine = DataEngine(data_args=data_args)
|
||||
|
||||
# 访问多模态样本
|
||||
sample = engine[0]
|
||||
print("用户消息内容:")
|
||||
for content_item in sample['messages'][0]['content']:
|
||||
print(f" 类型: {content_item['type']}, 值: {content_item['value']}")

```
|
||||
|
||||
---
|
||||
|
||||
**注意事项**:
|
||||
|
||||
1. 所有数据最终都会转换为标准的 Messages 格式
|
||||
2. 通过 `converter` 插件可以支持多种数据格式
|
||||
3. 通过 `weight` 和 `size` 参数可以灵活控制数据分布
|
||||
4. 支持同时使用本地数据集和 HuggingFace Hub 数据集
|
||||
5. 多模态数据通过在 `content` 中添加不同类型的元素来支持
|
||||

# DataEngine
|
||||
|
||||
## 1. DataEngine 简介
|
||||
|
||||
|
||||
`DataEngine` 是 LLaMA-Factory v1 数据处理的核心类,继承自 PyTorch 的 `Dataset`,负责各种插件的接入,其他功能(如数据格式转换、数据加载等)均通过插件的形式实现并接入 `DataEngine`。
|
||||
|
||||
`DataEngine`接受一个唯一入参:`DataArguments` 实例,所有的元数据集信息均通过该参数配置传入。
|
||||
|
||||
## 2. DataEngine 与 DataArguments 接口定义
|
||||
|
||||
```python
|
||||
@dataclass
|
||||

|
||||
""" `DataEngine`初始化入参

|

|

`DataArguments` 参数说明:
|
||||
|
||||
`dataset`: 数据集路径,支持本地或远程,当传入本地数据集文件路径时,需要满足该数据集为标准格式;否则需要传入 `dataset_info.yaml` 来配置数据集的 `converter` 等元信息,以告知 `DataEngine` 应当如何处理该数据。
|
||||
|
||||
`cutoff_len`: 数据集的截止长度,即该数据集的最大样本数量。
|
||||
|
||||
---
|
||||
|
||||
## 3. DataEngine 核心方法
|
||||
|
||||
### 3.1 `get_dataset_info`:加载数据元信息
|
||||
|
||||
根据 `dataset` 参数加载数据集配置,获取数据位置、数据格式、插件配置等所有数据元信息,在实例化 `DataEngine` 时会自动调用此方法。
|
||||
|
||||
### 3.2 加载数据集:`load_dataset`
|
||||
|
||||
遍历所有数据源,根据不同的数据源加载数据,在实例化 `DataEngine` 时会自动调用此方法。
|
||||
|
||||
```python
|
||||
for key, value in self.dataset_infos.items():
|
||||
split = value.get("split", "train")
|
||||
streaming = value.get("streaming", False)
|
||||
|
||||
if "hf_hub_url" in value:
|
||||
# 从 HF Hub 加载
|
||||
dataset = load_dataset(value["hf_hub_url"], split=split, streaming=streaming)
|
||||
else:
|
||||
# 使用 DataLoaderPlugin 加载本地文件
|
||||
dataset = DataLoaderPlugin(args=self.args).auto_load_data(value)
|
||||
|
||||
self.datasets[key] = dataset
|
||||
```
|
||||
|
||||
### 3.3 `build_data_index`:构建数据索引
|
||||
|
||||
为每个数据集创建索引列表 `[(dataset_name, sample_index), ...]`, `DataIndexPlugin`插件在此处被调用,可控制各数据集的采样频率、采样方式等,在实例化`DataEngine`时会自动调用此方法。
|
||||
|
||||
```python
|
||||
for dataset_name, dataset in self.datasets.items():
|
||||
# 创建基础索引
|
||||
data_index = [(dataset_name, idx) for idx in range(len(dataset))]
|
||||
|
||||
# 根据 size 和 weight 调整索引
|
||||
size = self.dataset_infos[dataset_name].get("size")
|
||||
weight = self.dataset_infos[dataset_name].get("weight")
|
||||
if size or weight:
|
||||
data_index = DataIndexPlugin().adjust_data_index(data_index, size, weight)
|
||||
|
||||
self.data_index.extend(data_index)
|
||||
```
|
||||
|
||||
### 3.4 `_convert_data_sample`:数据格式标准化
|
||||
|
||||
将原始数据转换为标准格式,`DataConverterPlugin`插件在此处被调用,具体调用的插件由 `get_dataset_info` 方法获取的 `converter` 信息指定,若 `converter` 为空则假定数据集为标准格式,此方法由`DataEngine`的 `__getitem__` 方法调用。
|
||||
|
||||
```python
|
||||
def _convert_data_sample(self, raw_sample: dict, dataset_name: str) -> Sample:
|
||||
converter = self.dataset_infos[dataset_name].get("converter")
|
||||
if converter is not None:
|
||||
# 使用指定的转换器
|
||||
from ..plugins.data_plugins.converter import get_converter
|
||||
return {"_dataset_name": dataset_name, **get_converter(converter)(raw_sample)}
|
||||
else:
|
||||
# 已经是标准格式
|
||||
return {"_dataset_name": dataset_name, **raw_sample}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 4. 初始化
|
||||
|
||||
`DataEngine` 初始化过程只需传入一个构建好的 `DataArguments` 即可,后续可通过该 `DataEngine` 访问数据集中的数据。
|
||||
|
||||
```python
|
||||
from llamafactory.v1.config.data_args import DataArguments
|
||||
from llamafactory.v1.core.data_engine import DataEngine
|
||||
|
||||
# 1. 创建数据参数
|
||||
data_args = DataArguments(
|
||||
dataset="~/data/v1_sft_demo.jsonl",
|
||||
cutoff_len=2048
|
||||
)
|
||||
|
||||
# 2. 初始化 Data Engine
|
||||
data_engine = DataEngine(data_args=data_args)
|
||||
|
||||
# 3. 访问数据
|
||||
sample = data_engine[0] # 获取第一个样本
|
||||
```
|
||||
|
||||
## 5. 数据访问方式
|
||||
|
||||
实例化后的`DataEngine`支持整数索引、列表索引、以及切片等访问方式,其数据读取用法可等价于 Python 列表。
|
||||
|
||||
```python
|
||||
sample = data_engine[0] # 获取第一个样本
|
||||
|
||||
sample = data_engine[0:10] # 获取前 10 个样本
|
||||
|
||||
sample = data_engine[[0, 5, 10]] # 获取指定索引的样本
|
||||
|
||||
```

# Data Plugins
|
||||
|
||||
## 1. Data Plugins 简介
|
||||
|
||||
## DataConverterPlugin
|
||||
|
||||
### 1. DataConverterPlugin 简介
|
||||
|
||||
DataConverter 负责将非标准格式的数据集转换为 v1 的标准 Messages 格式。这使得用户可以继续使用现有的数据集(如 Alpaca 格式),而无需手动转换。针对自定义格式的数据集,用户也可以通过构建对应的自定义 DataConverter 插件,来负责其数据格式标准化。
|
||||
|
||||
当前,LLaMA-Factory 已内置了 `Alpaca Converter` 和 `Pair Converter`,这两类数据集可以直接使用对应的 converter 进行标准化,无需自定义转换器。
|
||||
|
||||
|
||||
### 2. Alpaca Converter 详解
|
||||
|
||||
#### 2.1 Alpaca 格式
|
||||
|
||||
Alpaca 格式是一种常见的指令微调数据格式:
|
||||
|
||||
```json
|
||||
{
|
||||
"system": "You are a helpful assistant.",
|
||||
"instruction": "Describe a process of making crepes.",
|
||||
"input": "",
|
||||
"output": "Making crepes is an easy and delicious process..."
|
||||
}
|
||||
```
|
||||
|
||||
#### 2.2 Alpaca Converter 接口定义
|
||||
|
||||
```python
|
||||
class AlpacaSample(TypedDict, total=False):
|
||||
"""Alpaca 格式数据样本结构
|
||||
|
||||
attr:
|
||||
system (str, 可选): 系统提示信息(system prompt),用于设定对话背景或模型行为。
|
||||
instruction (str, 可选): 用户指令(user instruction),通常为任务描述。
|
||||
input (str, 可选): 额外的输入内容(input text),可与 instruction 拼接。
|
||||
output (str, 可选): 模型生成的目标输出(expected response)。
|
||||
"""
|
||||
...
|
||||
|
||||
|
||||
def alpaca_converter(raw_sample: AlpacaSample) -> SFTSample:
|
||||
"""将 Alpaca 样本转换为 SFT(Supervised Fine-Tuning)标准样本格式
|
||||
|
||||
`alpaca_converter` 将 Alpaca 数据集中一条样本转换为通用的 `SFTSample` 格式
|
||||
该格式用于监督微调(SFT)或多轮对话建模
|
||||
|
||||
转换逻辑:
|
||||
- 若存在 `system` 字段,则生成一条系统消息,loss_weight = 0.0
|
||||
- 若存在 `instruction` 或 `input` 字段,则合并为一条用户消息,loss_weight = 0.0
|
||||
- 若存在 `output` 字段,则生成一条助手机器人回复消息,loss_weight = 1.0
|
||||
|
||||
args:
|
||||
raw_sample (AlpacaSample): 原始 Alpaca 数据样本
|
||||
|
||||
return:
|
||||
SFTSample: 转换后的标准化样本,格式如下:
|
||||
|
||||
{
|
||||
"messages": [
|
||||
{"role": "system", "content": [{"type": "text", "value": "..."}], "loss_weight": 0.0},
|
||||
{"role": "user", "content": [{"type": "text", "value": "..."}], "loss_weight": 0.0},
|
||||
{"role": "assistant", "content": [{"type": "text", "value": "..."}], "loss_weight": 1.0},
|
||||
]
|
||||
}
|
||||
|
||||
example:
|
||||
>>> raw = {"instruction": "请将以下句子翻译成英文:", "input": "你好", "output": "Hello"}
|
||||
>>> alpaca_converter(raw)
|
||||
{
|
||||
"messages": [
|
||||
{"role": "user", "content": [{"type": "text", "value": "请将以下句子翻译成英文:你好"}], "loss_weight": 0.0},
|
||||
{"role": "assistant", "content": [{"type": "text", "value": "Hello"}], "loss_weight": 1.0}
|
||||
]
|
||||
}
|
||||
"""
|
||||
|
||||
```
|
||||
|
||||
#### 2.3 转换过程
|
||||
|
||||
`alpaca_converter` 函数将 Alpaca 格式转换为标准格式,转换逻辑如下:
|
||||
|
||||
```python
|
||||
def alpaca_converter(raw_sample: AlpacaSample) -> SFTSample:
|
||||
messages = []
|
||||
|
||||
# 1. 添加系统提示词(如果存在)
|
||||
if "system" in raw_sample:
|
||||
messages.append({
|
||||
"role": "system",
|
||||
"content": [{"type": "text", "value": raw_sample["system"]}],
|
||||
"loss_weight": 0.0
|
||||
})
|
||||
|
||||
# 2. 添加用户输入(instruction + input)
|
||||
if "instruction" in raw_sample or "input" in raw_sample:
|
||||
user_content = raw_sample.get("instruction", "") + raw_sample.get("input", "")
|
||||
messages.append({
|
||||
"role": "user",
|
||||
"content": [{"type": "text", "value": user_content}],
|
||||
"loss_weight": 0.0
|
||||
})
|
||||
|
||||
# 3. 添加模型回复
|
||||
if "output" in raw_sample:
|
||||
messages.append({
|
||||
"role": "assistant",
|
||||
"content": [{"type": "text", "value": raw_sample["output"]}],
|
||||
"loss_weight": 1.0
|
||||
})
|
||||
|
||||
return {"messages": messages}
|
||||
```
|
||||
|
||||
#### 2.4 转换示例
|
||||
|
||||
**输入(Alpaca 格式):**
|
||||
|
||||
```json
|
||||
{
|
||||
"instruction": "What is the capital of France?",
|
||||
"input": "",
|
||||
"output": "The capital of France is Paris."
|
||||
}
|
||||
```
|
||||
|
||||
**输出(标准格式):**
|
||||
|
||||
```json
|
||||
{
|
||||
"messages": [
|
||||
{
|
||||
"role": "user",
|
||||
"content": [{"type": "text", "value": "What is the capital of France?"}],
|
||||
"loss_weight": 0.0
|
||||
},
|
||||
{
|
||||
"role": "assistant",
|
||||
"content": [{"type": "text", "value": "The capital of France is Paris."}],
|
||||
"loss_weight": 1.0
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 自定义转换器
|
||||
|
||||
#### 3.1 创建自定义转换器
|
||||
|
||||
如果用户有自己的数据格式,可以轻松添加自定义转换器将其标准化,实现过程可参考如下示例:
|
||||
|
||||
```python
|
||||
# src/llamafactory/v1/plugins/data_plugins/converter.py
|
||||
|
||||
from typing import TypedDict, NotRequired
|
||||
from ...extras.types import SFTSample
|
||||
|
||||
# 1. 定义输入格式的类型
|
||||
class MyCustomSample(TypedDict, total=False):
|
||||
question: str
|
||||
answer: str
|
||||
context: NotRequired[str]
|
||||
|
||||
# 2. 实现转换逻辑
|
||||
def custom_converter(raw_sample: MyCustomSample) -> SFTSample:
|
||||
messages = []
|
||||
|
||||
# 构建用户消息
|
||||
user_text = raw_sample["question"]
|
||||
if "context" in raw_sample:
|
||||
user_text = f"Context: {raw_sample['context']}\n\nQuestion: {user_text}"
|
||||
|
||||
messages.append({
|
||||
"role": "user",
|
||||
"content": [{"type": "text", "value": user_text}],
|
||||
"loss_weight": 0.0
|
||||
})
|
||||
|
||||
# 构建助手消息
|
||||
messages.append({
|
||||
"role": "assistant",
|
||||
"content": [{"type": "text", "value": raw_sample["answer"]}],
|
||||
"loss_weight": 1.0
|
||||
})
|
||||
|
||||
return {"messages": messages}
|
||||
|
||||
# 3. 注册 custom_converter
|
||||
#src/llamafactory/v1/plugins/data_plugins/converter.py: CONVERTERS
|
||||
CONVERTERS = {
|
||||
"alpaca": alpaca_converter,
|
||||
"custom": custom_converter, # 添加自定义转换器
|
||||
}
|
||||
```
|
||||
|
||||
#### 3.2 使用自定义转换器
|
||||
|
||||
在 YAML 配置中指定转换器名称:
|
||||
|
||||
```yaml
|
||||
my_dataset:
|
||||
file_name: custom_data.json
|
||||
converter: custom
|
||||
```
|
||||

## DataLoaderPlugin
|
||||
|
||||
### 1. DataLoaderPlugin 简介
|
||||
|
||||
`DataLoaderPlugin` 负责从本地文件加载数据集,当前支持如下文件格式:
|
||||
|
||||
- **JSON**: `.json`
|
||||
- **JSONL**: `.jsonl`
|
||||
- **CSV**: `.csv`
|
||||
- **Parquet**: `.parquet`
|
||||
- **Arrow**: `.arrow`

## DataIndexPlugin
|
||||
|
||||
### 1. DataIndexPlugin 简介
|
||||
|
||||
`DataIndexPlugin` 负责调整数据索引,支持通过配置 `size`, `weight` 等参数控制数据集样本数量和采样频率。
|
||||
|
||||
- 使用 `size` 参数 限制使用的样本数量:
|
||||
|
||||
```yaml
|
||||
my_dataset:
|
||||
file_name: large_dataset.json
|
||||
size: 1000 # 只使用前 1000 个样本
|
||||
```
|
||||
|
||||
- 使用 `weight` 参数调整数据集在混合数据中的采样频率:
|
||||
|
||||
```yaml
|
||||
dataset_a:
|
||||
file_name: data_a.json
|
||||
weight: 1.0
|
||||
|
||||
dataset_b:
|
||||
file_name: data_b.json
|
||||
weight: 2.0 # dataset_b 的样本出现频率是 dataset_a 的 2 倍
|
||||
```
|
||||
|
||||
**说明**:`weight` 参数适用于在多个数据集混合训练时,调整不同数据集的的采样频率
|
||||
|
||||
- 当 `weight=1.0` 时,数据集按原始比例采样
|
||||
- 当 `weight=2.0` 时,该数据集的索引会复制 2 倍,使其样本出现频率翻倍
|
||||
|
||||
### 2. DataIndexPlugin 接口定义
|
||||
|
||||
```python
|
||||
@dataclass
|
||||
class DataIndexPlugin:
|
||||
"""数据索引插件(DataIndexPlugin)
|
||||
|
||||

|
||||

# Kernels plugins
|
||||
|
||||
## 概览
|
||||
LLaMA-Factory 通过 Kernels plugins 系统,依据不同硬件设备提供高性能计算内核(kernel)实现。该系统通过注册表机制管理所有 kernel,通过 `@register_kernel` 装饰器实现 kernel 定义后自动注册,由 `apply_kernel` 方法来使能指定的 kernel,`apply_default_kernels` 可使能注册表中当前环境所有可用的默认 kernels。
|
||||
|
||||
## 架构设计
|
||||
|
||||
### 核心组件
|
||||
|
||||
#### 1. Registry(注册表)
|
||||
|
||||
`Registry` 是一个用于管理所有 kernel 实现的静态类。它维护一个字典结构:`{kernel_id: KernelClass}`。
|
||||
|
||||
```python
|
||||
# 注册表结构示例
|
||||
{
|
||||
"npu_fused_rmsnorm": NpuRMSNormKernel,
|
||||
"npu_fused_swiglu": NpuSwiGluKernel,
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. register_kernel (装饰器)
|
||||
|
||||
`@register_kernel` 是 `Registry.register` 的别名。所有 kernel 类均应使用该装饰器进行注册。
|
||||
|
||||
**注册机制**:
|
||||
- 装饰器检查类是否继承自 `BaseKernel`。
|
||||
- 检查类是否定义了 `_kernel_id` 和 `_device` 属性。
|
||||
- 检查 `_device` 是否与当前运行环境的加速器类型匹配。如果不匹配,则跳过注册。
|
||||
- 如果一切符合要求,将 kernel 类注册到全局注册表中。
|
||||
|
||||
#### 3. BaseKernel(基类)
|
||||
|
||||
所有 kernel 的实现都必须继承自 `BaseKernel` 抽象基类。`BaseKernel` 定义了 kernel 的基本属性和接口。
|
||||
|
||||
#### 4. 标识系统
|
||||
|
||||
**Kernel ID** (`_kernel_id`):
|
||||
每个 kernel 必须拥有一个唯一的字符串标识符,例如 `"npu_fused_rmsnorm"`。
|
||||
|
||||
**Device Type** (`_device`):
|
||||
kernel 必须声明其支持的设备类型,例如 `DeviceType.NPU` 或 `DeviceType.CUDA`。
|
||||
|
||||
## Kernel 系统 API 设计
|
||||
|
||||
### **Registry**:全局 kernel 注册表
|
||||
|
||||
`Registry` 类提供了注册和获取 kernel 的接口:
|
||||
|
||||
```python
|
||||
class Registry:
|
||||
@classmethod
|
||||
def register(cls, kernel_cls: type[BaseKernel]) -> type[BaseKernel] | None:
|
||||
"""注册一个 kernel 类"""
|
||||
...
|
||||
|
||||
@classmethod
|
||||
def get(cls, kernel_id: str) -> type[BaseKernel] | None:
|
||||
"""根据 ID 获取 kernel 类"""
|
||||
...
|
||||
```
|
||||
|
||||
### **BaseKernel**
|
||||
|
||||
`BaseKernel` 定义了所有 kernel 必须实现的协议:
|
||||
|
||||
- `_kernel_id`: 类属性,kernel 的唯一标识符。
|
||||
- `_device`: 类属性,kernel 支持的设备类型。
|
||||
- `check_deps()`: 类方法,检查 kernel 的依赖项是否满足(如 `torch_npu` 是否安装)。
|
||||
- `apply(**kwargs)`: 抽象类方法,实现 kernel 的具体应用逻辑。
|
||||
|
||||
```python
|
||||
class BaseKernel(ABC):
|
||||
_kernel_id: Any = ""
|
||||
_device: DeviceType = DeviceType.CPU
|
||||
|
||||
@classmethod
|
||||
def check_deps(cls) -> bool:
|
||||
"""检查依赖项"""
|
||||
...
|
||||
|
||||
@classmethod
|
||||
@abstractmethod
|
||||
def apply(cls, **kwargs) -> HFModel:
|
||||
"""应用 kernel 到模型"""
|
||||
...
|
||||
```
|
||||
|
||||
### **scan_all_kernels**
|
||||
|
||||
`scan_all_kernels` 函数会自动扫描 `ops` 目录下的所有 `.py` 文件并导入它们,从而触发 `@register_kernel` 装饰器完成自动注册。
|
||||
|
||||
### **apply_kernel**
|
||||
|
||||
对模型使能指定的 kernel。
|
||||
|
||||
```python
|
||||
def apply_kernel(kernel_id: str, **kwargs) -> HFModel:
|
||||
"""应用指定的 kernel 到模型
|
||||
|
||||
Args:
|
||||
kernel_id: 目标 kernel 的 ID
|
||||
**kwargs: 传递给 kernel.apply 的参数,通常包含 model
|
||||
"""
|
||||
```
|
||||
|
||||
**用法示例**:
|
||||
```python
|
||||
from llamafactory.v1.plugins.model_plugins.kernels import apply_kernel
|
||||
|
||||
model = apply_kernel("npu_fused_rmsnorm", model=model)
|
||||
```
|
||||
|
||||
### **apply_default_kernels**
|
||||
|
||||
对模型使能所有默认注册的 kernel。这是一个高级 API,通常在模型加载流程中自动调用。
|
||||
|
||||
```python
|
||||
def apply_default_kernels(model: HFModel, include_kernels: str = None) -> HFModel:
|
||||
"""应用所有默认 kernel
|
||||
|
||||
Args:
|
||||
model: HFModel 实例
|
||||
include_kernels: 包含的 kernel ID 列表(逗号分隔字符串),或者 "auto"/True 表示全部
|
||||
"""
|
||||
```
|
||||
|
||||
## 扩展 Kernels
|
||||
|
||||
如果用户有针对特定模型或者设备的 kernel,可以按照下述步骤去实现并接入 LLaMA-Factory。
|
||||
|
||||
### 创建新 Kernel 的步骤
|
||||
|
||||
#### 1. 创建 Kernel 实现文件
|
||||
|
||||
在 `src/llamafactory/v1/plugins/model_plugins/kernels/ops` 下的相应子目录中创建新的 kernel 实现文件,例如 `mlp/cuda_swiglu.py`:
|
||||
|
||||
```python
|
||||
import torch
|
||||
from ......accelerator.helper import DeviceType
|
||||
from ......utils.types import HFModel
|
||||
from ...base import BaseKernel
|
||||
from ...registry import register_kernel
|
||||
|
||||
# 实现具体的 kernel 函数
|
||||
def _cuda_swiglu_forward(self, hidden_state):
|
||||
# ... CUDA 优化实现 ...
|
||||
pass
|
||||
|
||||
@register_kernel
|
||||
class CudaSwiGluKernel(BaseKernel):
|
||||
_kernel_id = "cuda_fused_swiglu"
|
||||
_device = DeviceType.CUDA
|
||||
|
||||
@classmethod
|
||||
def apply(cls, **kwargs) -> HFModel:
|
||||
model = kwargs.get("model")
|
||||
if model is None:
|
||||
raise ValueError("model is required")
|
||||
|
||||
if not cls.check_deps():
|
||||
raise RuntimeError("Dependencies not met")
|
||||
|
||||
# 遍历模型并替换 forward 方法
|
||||
for name, module in model.named_modules():
|
||||
# ... 匹配和替换逻辑 ...
|
||||
pass
|
||||
|
||||
return model
|
||||
```
|
||||
|
||||
#### 2. 自动发现
|
||||
|
||||
由于 `scan_all_kernels` 会自动扫描 `ops` 目录,只要文件位于该目录下且没有语法错误,系统启动时会自动导入并注册,无需手动修改注册表代码。
|
||||
|
||||
#### 3. 测试 Kernel
|
||||
|
||||
创建测试用例验证 kernel 的正确性:
|
||||
|
||||
```python
|
||||
from llamafactory.v1.plugins.model_plugins.kernels import apply_kernel
|
||||
|
||||
# ... 加载模型 ...
|
||||
model = apply_kernel("cuda_fused_swiglu", model=model)
|
||||
# ... 验证 forward 是否被替换 ...
|
||||
```
|
||||
|
||||
## 异常处理
|
||||
|
||||
### 依赖不可用
|
||||
|
||||
`BaseKernel.check_deps()` 默认会检查当前设备类型是否匹配。子类可以重写此方法以添加额外的依赖检查(如检查特定的库是否安装)。如果 `check_deps()` 返回 `False`,`apply()` 方法应当抛出异常或进行相应处理。
|
||||
|
||||
### Kernel ID 未找到
|
||||
|
||||
如果调用 `apply_kernel` 时传入了不存在的 `kernel_id`,会抛出 `ValueError`。

||||
|
||||
> [!IMPORTANT]
|
||||
> 此步骤为必需。
|
||||
|
||||
#### 从源码安装
|
||||
|
||||
```bash
|
||||
git clone --depth 1 https://github.com/hiyouga/LlamaFactory.git
|
||||
cd LlamaFactory
|
||||
pip install -e .
|
||||
```
|
||||
|
||||
|
||||
### 数据准备
|
||||
|
||||
关于数据集文件的格式,请参考 [data-preparation/README.md](data-preparation/README.md) 的内容。你可以使用 HuggingFace / ModelScope 上的数据集或加载本地数据集。
|
||||
|
||||
> [!NOTE]
|
||||
> 使用自定义数据集或自定义数据集格式时,请参照 [data-preparation/README.md](data-preparation/README.md) 进行配置,如有必要,请重新实现自定义数据集的数据处理逻辑,包括对应的`converter`。
|
||||
|
||||
您也可以使用 **[Easy Dataset](https://github.com/ConardLi/easy-dataset)**、**[DataFlow](https://github.com/OpenDCAI/DataFlow)** 和 **[GraphGen](https://github.com/open-sciencelab/GraphGen)** 构建用于微调的合成数据。
