fix: 算力节点任务/GPU 统计纳入评测与推理占用，补充测试依赖

- compute_nodes() 的 current_running_jobs 纳入运行中的评测任务（eval_tasks）
  与已加载的推理模型（compare_tasks 持久化状态 + 内存标记兜底），
  多节点时 GPU 被评测/推理占用不再显示 0/1
- gpus() 直接按 eval_tasks / compare_tasks 派生 GPU busy/reserved 状态，
  修复 gpu_id=0 时 or -1 导致匹配失败；删除评测后 GPU 不再残留 busy
- 评测不再复用 mark_inference_loaded 内存标记，GPU 占用由任务数据驱动
- requirements.txt 补充 pytest / ruff（此前仅声明在 pyproject dev 可选依赖）

 ## 算力服务启动
 
+算力服务是一个 FastAPI 应用，同时承载 Compute API（模型训练/推理/GPU 管理）和 File Gateway（文件上传下载）路由。Docker 部署时对外暴露两个端口（19100 和 19101）均指向同一服务，方便应用平台分别配置 `api_base_url` 和 `file_gateway_url`。本地开发只需启动一个进程。
+
+### 方式一：Docker 启动（推荐）
+
 ```bash
-cd compute
+cd docker/compute
-uvicorn api.main:app --reload --port 19100
+cp .env.example .env
+docker compose up -d
 ```
 
-默认 `COMPUTE_MODE=real`。真实 GPU 接入时，在每台算力服务器上部署 Compute API、Agent、File Gateway 和 LLaMA-Factory，应用平台通过 `compute_nodes.api_base_url` 和 `compute_nodes.file_gateway_url` 主动轮询。仅在隔离联调环境可显式设置 `COMPUTE_MODE=simulator` 或 `COMPUTE_EXECUTION_MODE=simulator`。
+### 方式二：本地开发启动
+
+**Windows (cmd)：**
+
+```cmd
+cd /d E:\yg_ft\compute
+set PYTHONPATH=E:\yg_ft
+.\.venv\Scripts\python.exe -m uvicorn api.main:app --reload --port 19100
+```
+
+> `PYTHONPATH=E:\yg_ft` 是必需的，因为代码使用 `from compute.agent...` 绝对导入。
+
+**Linux / macOS：**
+
+```bash
+cd compute
+PYTHONPATH=.. uvicorn api.main:app --reload --port 19100
+```
+
+### 环境变量说明
+
+| 变量 | 默认值 | 说明 |
+|---|---|---|
+| `COMPUTE_MODE` | `real` | `real` / `simulator`，仅隔离联调用 simulator |
+| `COMPUTE_EXECUTION_MODE` | `real` | 训练执行模式 |
+| `COMPUTE_SERVICE_TOKEN` | `change_me` | 服务间认证 token |
+| `MODELTF_ROUTE_PREFIX` | `/modelTF` | API 路由前缀 |
+
+应用平台通过数据库 `compute_nodes` 表中的 `api_base_url` 和 `file_gateway_url` 主动轮询算力节点状态。

+# 模型评测功能总结
+
+本项目（基于 LLaMA-Factory 的微调训练平台）包含 **4 套相对独立** 的模型评测能力，分别面向不同的使用场景：
+
+| 能力 | 入口/目录 | 评测类型 | 打分方式 |
+| --- | --- | --- | --- |
+| 1. 学术 Benchmark 评测 | `llamafactory/eval/` | 选择题式基准（类 MMLU/C-Eval） | 选项匹配 + few-shot |
+| 2. 评估工作台 | `backend/app/api/v1/eval/` | 生成式问答（指令跟随） | BLEU / ROUGE / ExactMatch + 可选 LLM 评审 |
+| 3. 平台评估系统 | `backend/app/api/v1/evaluation/` | 基于评估数据集的问答 | 判卷模型（judge model）打分（0–5 分） |
+| 4. 训练时验证评估 | `backend/app/services/task_runner.py` | 训练验证集 | loss 指标 |
+
+下面分别说明。
+
+---
+
+## 1. 学术 Benchmark 评测（LLaMA-Factory 原生）
+
+面向标准学术选择题基准（如 MMLU、C-Eval 等），复用 LLaMA-Factory 原生的评测框架。
+
+**核心文件**
+- `llamafactory/eval/evaluator.py`：`Evaluator` 类 + `run_eval()` 入口
+- `llamafactory/eval/template.py`：评测 prompt 模板（中/英，含 few-shot 示例构建）
+- `llamafactory/hparams/evaluation_args.py`：`EvaluationArguments` 配置类
+
+**工作流程**
+1. 按 `task`（benchmark 名称）加载数据集，按科目（subject）拆分。
+2. 每个样本构造 few-shot 提示词（`n_shot` 控制示例数，由 `lang` 决定中/英模板），将题干与候选选项拼入 prompt。
+3. 调用模型推理得到预测，与标准答案比对，统计每个科目及整体的 `accuracy`。
+4. 结果写入 `save_dir`，打印各科目与平均准确率。
+
+**关键参数（`EvaluationArguments`）**
+- `task`：基准数据集名
+- `batch_size` / `n_shot` / `lang` / `save_dir` / `seed`
+- `model_name_or_path`、`template`、`trust_remote_code` 等模型相关参数
+
+> 该能力属于框架底层，本平台前端未直接提供操作入口，主要通过配置文件/脚本调用。
+
+---
+
+## 2. 评估工作台（生成式评测 + 指标计算）
+
+后端路由位于 `backend/app/api/v1/eval/__init__.py`，前端称为「评估工作台」。**适用于评测模型的指令跟随与生成质量**，并支持 LLM 作为裁判（LLM-as-a-Judge）。
+
+**API 端点**
+- `GET  /evaluation/tasks`：列出评测任务（`frontend/src/api/evaluation.ts:listTasks`）
+- `POST /evaluation/run`：提交一次评测（`runEval`）
+- `GET  /evaluation/report/{task_id}`：拉取评测报告（`getReport`）
+- `DELETE /evaluation/tasks/{task_id}`：删除任务（`deleteTask`）
+
+**评测流程（`run_eval`）**
+1. 通过 **LLaMA-Factory 数据管道**（`get_dataset`) 加载数据集，支持 `subset` 与抽样（`eval_sample`）。
+2. 用 **原生 transformers** 加载模型在本地做生成推理（单进程顺序生成，便于展示样本）。
+3. 计算客观指标（`compute_score`）：
+   - `BLEU`（sacrebleu）
+   - `ROUGE-1 / ROUGE-2 / ROUGE-L`（rouge-score）
+   - `Exact Match`
+4. **可选 LLM 评审**（judge）：当配置了 `judge_model` / `judge_api_base` / `judge_api_key` 时，调用 OpenAI 兼容接口对每条样本打分（10 分制），并输出 4 个维度与理由：
+   - 核心事实正确性 `factual`
+   - 信息完整性 `completeness`
+   - 无幻觉 `no_hallucination`
+   - 格式合规性 `format`
+   - 综合分 `score` + `reason`
+5. 任务状态持久化在后端 `eval_tasks.json`（支持 running/completed/failed/stopped），前端轮询进度。
+
+**前端页面**
+- `frontend/src/views/evaluation/EvaluateTask.vue`：任务列表、创建评测对话框（选模型、数据集、指标、可选 judge 配置）
+- `frontend/src/views/evaluation/EvaluateReport.vue`：报告页，展示综合得分、BLEU、ROUGE-L、各维度指标及「参考答案 vs 模型预测 vs LLM 评审」对比样例
+
+---
+
+## 3. 平台评估系统（基于评估数据集 + 判卷模型）
+
+后端路由位于 `backend/app/api/v1/evaluation/__init__.py`，是平台业务层自研的评测体系。通过「评估数据集」组织题目，可一次性对 **多个被测模型 + 指定判卷模型** 进行批量评分。
+
+**核心概念（数据模型 `backend/app/models/models.py`）**
+- `EvalDataset`（`models.py:131`）：评估数据集，从项目问答对（`Question`/`Chunk`）中按 `question_type`（mixed/fact/reasoning）选题构建，状态 `pending/running/completed/failed`。
+- `EvalResult`（`models.py:147`）：单条评测结果，含 `judge_score`（0–5 分）、`is_correct`（true/false/partial）、`feedback`、`expected_answer` 等。
+- `Task`（`models.py:184`）：后台任务，`task_type="model-evaluation"`，记录进度与 `model_info`（存放平均分等汇总）。
+
+**评测流程（`process_evaluation_task`，`backend/app/services/task_processor.py:336` 起）**
+1. 加载评估数据集关联的题目，可选带入 `chunk` 上下文（RAG 场景）。
+2. 对每道题，先用 `build_eval_prompt` 组合「上下文 + 题目 + 参考答案」，调用 **判卷模型**（`call_model`，temperature=0.3）生成评分。
+3. `parse_eval_result` 解析出 `score`(0–5)、`is_correct`、`feedback`，写入 `EvalResult`。
+4. 逐题提交进度（`completed_count` / `progress`），支持中途 `stopped`。
+5. 汇总：`avg_score = 总分/有效数 × 20`（换算百分制），`avg_score_5 = 总分/有效数`（5 分制），存入 `task.model_info`。判定规则：得分 **≥3 视为正确**。
+
+**特点**
+- 判卷与被测模型解耦：被测模型给出答案，判卷模型（judge）独立评分，降低自评偏差。
+- 支持失败隔离：单题异常写入 `evaluation_status: failed` 记录而不中断整体任务。
+
+---
+
+## 4. 训练时验证评估
+
+在微调训练任务执行期间，由 `backend/app/services/task_runner.py` 的 `do_eval` 触发：
+
+- 在训练过程中对验证集（validation set）计算 `eval_loss`，用于监控过拟合。
+- 结果回填到 `Task` 的 `loss_info` / `detail`，前端绘制 loss 曲线。
+- 属于训练配套的轻量评估，不参与上述 1–3 的业务评测。
+
+---
+
+## 附属：前端评测相关页面
+
+| 文件 | 作用 |
+| --- | --- |
+| `frontend/src/views/evaluation/EvaluateTask.vue` | 评估工作台：任务列表 + 创建评测 |
+| `frontend/src/views/evaluation/EvaluateReport.vue` | 评估报告：指标卡 + 维度标签 + 对比样例 |
+| `frontend/src/api/evaluation.ts` | 评估工作台接口封装 |
+| 平台评估系统入口 | 评估数据集管理 + 评估任务（model-evaluation）创建与结果查看 |
+
+---
+
+## 小结
+
+- **想要学术榜单式准确率** → 用能力 1（LLaMA-Factory `eval/`）。
+- **想要开放式生成质量（BLEU/ROUGE + LLM 评审）** → 用能力 2（评估工作台 `/evaluation/run`）。
+- **想要基于自有问答数据、用判卷模型批量打分** → 用能力 3（平台评估系统 `model-evaluation` 任务）。
+- **训练过程监控** → 能力 4（`do_eval` 验证集 loss）。

+# 平台治理功能说明
+
+平台治理涵盖用户管理、租户管理、项目管理、审批管理、审计日志、资源授权(ACL)、留存策略等企业管理能力。功能入口位于侧边栏「平台治理」和「系统设置」两个分组下。
+
+本平台核心业务是**模型微调**：用户上传数据 → 数据处理 → 模型训练 → 模型评测 → 模型推理。平台治理负责管理**谁**能访问**哪个租户/项目**的**哪些资源**。

+## 6. 平台性能
+
+**对应页面**：`HardwareView.vue`  
+**后端接口**：`GET /system-info`、`GET /health`（顶部栏实时指标）
+
+### 页面内容
+
+**概览卡片**：CPU（型号/核心数/使用率）、内存（已用/总量/使用率）、磁盘（已用/总量/使用率）、网络吞吐
+
+**趋势图**：CPU/内存/磁盘/GPU 利用率折线图（最近 60 次采样，1/3/5/10秒自动刷新）
+
+**GPU 资源池**：每张卡展示名称、状态、利用率、显存、温度、功耗、风扇转速；点击卡片查看详情抽屉（设备属性、趋势图、进程列表）
+
+**主机信息**：OS、运行时长、进程数、GPU 驱动版本
+
+### 当前缺失
+- [ ] 历史数据持久化（刷新后采样清空）
+- [ ] 告警阈值设置

+**对应页面**：`LogsView.vue`（系统日志 + 训练日志双 Tab）
+
+### 系统日志
+
+- 按日期选择日志文件
+- 关键词搜索
+- 日志级别筛选（INFO/WARN/ERROR/DEBUG）
+- 自动刷新（5/10/30/60 秒可调）
+
+### 训练日志
+
+- 按 PID 选择训练日志文件
+- 同样支持搜索和级别筛选
+
+### 当前缺失
+- [ ] 日志下载/导出
+- [ ] 分页或虚拟滚动（大文件加载慢）
+- [ ] 行号显示
+

+用户登录 → 分配角色(admin/operator/viewer) + 页面权限
+    │
+    ├─ 创建租户（配额：GPU/存储/项目数）
+    │     └─ 关联用户
+    │
+    ├─ 创建项目（关联租户，选择编码ID）
+    │     ├─ 项目成员（角色：member/admin/viewer）
+    │     └─ 资源授权(ACL)：谁对什么资源有什么权限
+    │
+    ├─ 创建审批模板（定义审批流程）
+    │     └─ 审批实例：敏感操作需要审批（通过/拒绝）
+    │
+    ├─ 审计日志：所有操作自动记录（谁在什么时间做了什么）
+    │
+    └─ 留存策略：定义数据保留周期，自动清理过期数据
