一、知识总结
本项目使用 GoogLeNet (Inception v1) 网络结构实现猴痘病（Monkeypox）的二分类识别任务。
- 数据集：猴痘皮肤图像数据集（Monkeypox / Others 两类）
- 模型：Inception v1 (GoogLeNet)，含 9 个 Inception Module
- 框架：PyTorch二、代码实现

2.1 识别数据路径
# 定义数据目录

# 获取类别名
data_paths = list(data_dir.glob('*'))
classeNames = [path.name for path in data_paths]

3.1 Inception Module 定义
Inception Module 的核心思想：使用不同大小的卷积核（1x1、3x3、5x5）和最大池化并行提取不同尺度的特征，然后沿通道维度拼接。
使用 1x1 卷积核进行降维，大幅减少参数量和计算量。
