+```
+
+## 🔧 模型管理器API
+
+### 主要方法
+
+#### 1. 保存模型
+```python
+model_path = model_manager.save_model(
+    model_data=model_data,
+    product_id='P001',
+    model_type='tcn',
+    version='v1',
+    store_id='S001',                    # 可选，店铺模式需要
+    training_mode='product',            # 'product', 'store', 'global'
+    aggregation_method='sum',           # 可选，全局模式需要
+    product_name='感冒灵颗粒'
+)
+```
+
+#### 2. 列出模型
+```python
+# 列出所有模型
+models = model_manager.list_models()
+
+# 按条件过滤
+models = model_manager.list_models(
+    product_id='P001',                  # 按产品过滤
+    model_type='tcn',                   # 按模型类型过滤
+    store_id='S001',                    # 按店铺过滤
+    training_mode='product'             # 按训练模式过滤
+)
+```
+
+#### 3. 解析文件名
+```python
+info = model_manager.parse_model_filename('tcn_product_P001_v1.pth')
+# 返回：
+# {
+#     'model_type': 'tcn',
+#     'product_id': 'P001',
+#     'version': 'v1',
+#     'training_mode': 'product',
+#     'store_id': None,
+#     'aggregation_method': None
+# }
+```
+
+#### 4. 获取特定模型
+```python
+model = model_manager.get_model_by_id('tcn_product_P001_v1')
+```
+
+## 🚀 版本管理策略
+
+### 版本号规则
+- **v1**: 初始版本
+- **v2, v3, ...**: 后续优化版本
+- **自动递增**: 同一配置下重新训练自动生成新版本
+
+### 版本冲突处理
+- 相同产品、模型类型、训练模式的模型会自动生成新版本号
+- 避免意外覆盖之前训练的模型
+- 支持模型版本对比和回滚
+
+## 📊 兼容性支持
+
+### 支持的旧格式
+系统可以解析和处理以下旧格式文件名：
+- `transformer_model_product_P001_v1.pth`
+- `P001_mlstm_v1_global_model.pt`
+- `kan_optimized_model_product_P001.pth`
+
+### 迁移策略
+- 旧格式模型可以正常读取和使用
+- 重新训练时会使用新的标准化命名
+- 提供迁移工具将旧格式转换为新格式
+
+## 🛠️ 使用示例
+
+### 1. 训练并保存模型
+```python
+from core.predictor import PharmacyPredictor
+
+predictor = PharmacyPredictor()
+
+# 产品模式训练
+metrics = predictor.train_model(
+    product_id='P001',
+    model_type='tcn',
+    epochs=50,
+    training_mode='product'
+)
+
+# 店铺模式训练
+metrics = predictor.train_model(
+    product_id='P001',
+    model_type='mlstm',
+    epochs=50,
+    training_mode='store',
+    store_id='S001'
+)
+
+# 全局模式训练
+metrics = predictor.train_model(
+    product_id='P001',
+    model_type='transformer',
+    epochs=50,
+    training_mode='global',
+    aggregation_method='sum'
+)
+```
+
+### 2. 加载和预测
+```python
+from predictors.model_predictor import load_model_and_predict
+
+# 使用特定模型进行预测
+predictions = load_model_and_predict(
+    product_id='P001',
+    model_type='tcn',
+    training_mode='product',
+    store_id=None
+)
+```
+
+## 📈 性能和监控
+
+### 存储效率
+- 统一目录避免文件分散
+- 标准化命名便于查找和管理
+- 支持大量模型文件的高效检索
+
+### 元数据管理
+- 每个模型包含完整的训练信息
+- 支持模型性能对比和分析
+- 便于模型版本管理和回滚
+
+## 🔄 更新日志
+
+### v2.1.0 (2025-06-21)
+- ✅ 实现统一模型命名规范
+- ✅ 创建标准化模型管理器
+- ✅ 支持三种训练模式的文件名格式
+- ✅ 添加完整的元数据管理
+- ✅ 实现版本自动管理

+# 中文乱码问题解决方案总结
+
+## 📋 问题回顾
+
+### 原始问题
+1. **训练时控制台无日志输出** - API服务器训练模型时控制台没有任何显示
+2. **中文字符乱码** - 控制台输出中文显示为乱码或问号
+3. **表情符号无法显示** - 🚀 📊 等表情符号显示异常
+
+### 环境背景
+- **运行环境**: Windows + uv Python包管理器
+- **项目特点**: 大量使用中文注释和表情符号增强可读性
+- **问题影响**: 开发调试体验严重受影响
+
+## 🔍 根本原因分析
+
+### 1. Python运行环境编码
+- `uv run` 启动的Python进程默认编码可能不是UTF-8
+- Windows系统默认使用GBK编码
+- 环境变量 `PYTHONIOENCODING` 未正确设置
+
+### 2. 控制台输出流配置
+- `sys.stdout` 和 `sys.stderr` 编码配置不正确
+- 缓冲机制导致输出延迟或丢失
+- Windows控制台代码页设置不当
+
+### 3. 脚本文件编码
+- Python脚本文件保存编码与运行时编码不匹配
+- UTF-8 BOM头处理问题
+
+## ✅ 解决方案实施
+
+### 第一步：环境变量修复
+```bash
+# 核心解决方案：设置环境变量
+PYTHONIOENCODING=utf-8 uv run server/api.py
+```
+
+**原理**: 强制Python使用UTF-8编码处理输入输出流
+
+### 第二步：代码内编码强化
+在 `server/api.py` 中添加：
+```python
+import sys
+import os
+
+# 设置环境变量强制UTF-8编码
+os.environ['PYTHONIOENCODING'] = 'utf-8'
+os.environ['PYTHONLEGACYWINDOWSSTDIO'] = '0'
+
+# Windows系统特殊处理
+if os.name == 'nt':
+    try:
+        os.system('chcp 65001 >nul 2>&1')  # 设置控制台代码页
+        if hasattr(sys.stdout, 'reconfigure'):
+            sys.stdout.reconfigure(encoding='utf-8', errors='replace')
+            sys.stderr.reconfigure(encoding='utf-8', errors='replace')
+    except Exception as e:
+        print(f"Warning: Failed to set UTF-8 encoding: {e}")
+```
+
+### 第三步：批处理文件方案
+创建 `启动API服务器.bat`：
+```batch
+@echo off
+chcp 65001 >nul 2>&1
+set PYTHONIOENCODING=utf-8
+set PYTHONLEGACYWINDOWSSTDIO=0
+cd /d %~dp0
+echo 🚀 启动药店销售预测系统API服务器...
+uv run server/api.py
+pause
+```
+
+### 第四步：训练器输出修复
+在 `server/trainers/transformer_trainer.py` 中：
+```python
+def emit_progress(message, progress=None, metrics=None):
+    # 强制刷新输出缓冲区
+    print(f"[{time.strftime('%H:%M:%S')}] {message}", flush=True)
+    import sys
+    sys.stdout.flush()
+    sys.stderr.flush()
+```
+
+## 📊 修复效果验证
+
+### Before (修复前)
+```
+使用设备: cuda
+成功加载数据文件: pharmacy_sales_multi_store.csv
+数据标准化完成，可用特征列: ['sales', 'price', ...]
+模型训练失败: 'gbk' codec can't encode character '\U0001f916'
+```
+
+### After (修复后)
+```

+📊 模型评估指标:
+   MSE: 226.7259
+   RMSE: 15.0574
+   ✅ 训练成功完成
+```
+
+## 🎯 最佳实践总结
+
+### 1. 统一启动方式
+**强制要求**: 所有 `uv run` 命令前添加环境变量
+```bash
+PYTHONIOENCODING=utf-8 uv run [script_name]
+```
+
+### 2. 代码防御性编程
+在关键脚本开头添加编码配置代码，确保兼容性
+
+### 3. 使用批处理文件
+为常用操作创建预配置的启动脚本，避免重复设置
+
+### 4. 测试验证机制
+创建编码测试脚本，每次修改后验证编码正常
+
+## 📋 问题预防清单
+
+### 开发阶段
+- [ ] 新脚本复制已验证的编码配置代码
+- [ ] 文件保存时确保UTF-8编码
+- [ ] 使用统一的启动方式
+
+### 部署阶段  
+- [ ] 环境变量正确设置
+- [ ] 控制台支持UTF-8显示
+- [ ] 批处理文件配置正确
+
+### 维护阶段
+- [ ] 定期运行编码测试
+- [ ] 团队成员统一开发规范
+- [ ] 文档保持更新
+
+## 🚀 后续优化建议

+2. **IDE集成**: 配置开发环境默认使用UTF-8
+3. **CI/CD集成**: 在持续集成中包含编码测试
+4. **文档完善**: 在README中明确说明编码要求
+
+## 💡 经验教训
+
+1. **环境变量优先**: `PYTHONIOENCODING=utf-8` 是最简单有效的解决方案
+2. **代码容错**: 即使环境配置失败，代码内配置可以作为后备
+3. **用户体验**: 表情符号和中文大大提升了日志的可读性，值得保留
+4. **文档重要性**: 详细记录解决方案避免重复踩坑

+### 1. 增强Windows UTF-8编码支持
+
+**修改文件:** `server/api.py`
+
+**修复内容:**
+```python
+# 强化UTF-8编码配置
+if os.name == 'nt':  # Windows系统
+    os.system('chcp 65001 >nul 2>&1')
+    os.system('cls >nul 2>&1' if os.name == 'nt' else 'clear')
+    import io
+    sys.stdout = io.TextIOWrapper(sys.stdout.buffer, encoding='utf-8', errors='replace', line_buffering=True)
+    sys.stderr = io.TextIOWrapper(sys.stderr.buffer, encoding='utf-8', errors='replace', line_buffering=True)
+    sys.stdout.reconfigure(encoding='utf-8', errors='replace', line_buffering=True)
+    sys.stderr.reconfigure(encoding='utf-8', errors='replace', line_buffering=True)
+```
+
+### 2. 优化日志配置
+
+**修改内容:**
+```python
+# 增强中文支持的日志配置
+logging.basicConfig(
+    level=logging.INFO,
+    format='[%(asctime)s] %(levelname)s - %(message)s',
+    datefmt='%H:%M:%S',
+    handlers=[
+        logging.StreamHandler(sys.stdout),
+        logging.FileHandler('api.log', encoding='utf-8')
+    ],
+    force=True  # 强制重新配置日志
+)
+
+# 设置所有logger立即刷新
+for handler in logging.root.handlers:
+    if isinstance(handler, logging.StreamHandler):
+        handler.stream = sys.stdout
+        handler.flush = lambda: handler.stream.flush()
+```
+
+### 3. 美化训练进度输出
+
+**修改内容:**
+- 将原始的debug信息转换为用户友好的表情符号输出
+- 所有print语句添加 `flush=True` 参数
+- 关键节点添加 `sys.stdout.flush()` 强制刷新
+
+**输出示例:**
+```
+🚀 训练任务开始: task-12345
+📋 任务详情: 训练 TRANSFORMER 模型 - 药品 P001
+⚙️ 配置参数: 共 50 个轮次
+🏷️ 版本信息: 版本号 v1.0, 模型标识: P001
+🤖 调用 TRANSFORMER 训练器 - 产品: P001
+📊 Epoch 10/50, 训练损失: 0.0234, 测试损失: 0.0245
+📈 训练完成! 结果类型: <class 'dict'>
+💾 模型保存路径: saved_models/transformer/P001_v1.0.pth
+✔️ 任务状态更新: 已完成, 版本: v1.0
+```
+
+### 4. 修复训练器输出
+
+**修改文件:** `server/trainers/transformer_trainer.py`
+
+**修复内容:**
+- emit_progress函数添加强制缓冲区刷新
+- 训练进度输出添加表情符号增强可读性
+- 评估指标输出格式化并添加表情符号
+
+## ✅ 修复效果验证
+
+### 测试1: 基础控制台输出
+```bash
+python test_console_output.py
+```
+**结果:** ✅ 中文和表情符号完美显示
+
+### 测试2: API日志输出
+```bash
+python test_api_logging.py
+```
+**结果:** ✅ Logger和print混合输出正常，文件日志正确保存
+
+### 测试3: 实际训练测试
+现在可以启动API服务器进行实际训练测试：
+```bash
+uv run server/api.py
+```
+
+## 📊 修复前后对比
+
+| 项目 | 修复前 | 修复后 |
+|------|--------|--------|
+| 控制台输出 | ❌ 无输出 | ✅ 丰富的实时输出 |
+| 中文支持 | ❌ 乱码 | ✅ 完美显示 |
+| 表情符号 | ❌ 不显示 | ✅ 完美显示 |
+| 进度反馈 | ❌ 无反馈 | ✅ 详细进度信息 |
+| 日志文件 | ❌ 可能乱码 | ✅ UTF-8编码正确 |
+| 缓冲刷新 | ❌ 延迟输出 | ✅ 立即输出 |
+
+## 🎯 核心改进点
+
+1. **编码支持**: 强化Windows控制台UTF-8支持
+2. **缓冲管理**: 启用行缓冲和强制刷新机制
+3. **输出美化**: 使用表情符号和结构化输出提升可读性
+4. **双重输出**: print + logger确保输出可见性和日志记录
+5. **实时反馈**: 训练过程中的详细进度信息
+
+## 🚀 使用建议
+
+启动API服务器时，现在将看到完整的中文训练日志：
+
+```bash
+cd server
+uv run api.py
+```
+
+前端训练时控制台将显示：
+- 🚀 任务启动信息
+- 📋 训练配置详情  
+- 🤖 模型训练进度
+- 📊 实时损失曲线
+- 💾 模型保存状态
+- ✔️ 任务完成确认
+
+所有输出现在都支持完整的中文和表情符号显示，大大改善了开发和调试体验。
