本次项目的文件

main.py主程序如下

1. 导入必要的库和模块：

   • 导入 TensorFlow 库以及自定义的 FaceAging 模块。
   • 导入操作系统库和参数解析库。

2. 定义 str2bool 函数：

   • 自定义函数用于将字符串转换为布尔值。

3. 创建命令行参数解析器：

   • 使用 argparse.ArgumentParser 创建解析器，设置命令行参数的相关信息，如是否训练、轮数、数据集名称等。

4. 主函数 main(_) 入口：

   • 打印设置的参数。
   • 配置 TensorFlow 会话，设置 GPU 使用等。

5. 在 with tf.Session(config=config) as session 中：

   • 创建 FaceAging 模型实例，传入会话、训练模式标志、保存路径和数据集名称。

6. 判断是否训练模式：

   • 如果是训练模式，根据参数决定是否使用预训练模型进行训练。
   • 如果不使用预训练模型，执行预训练步骤，并在预训练完成后开始正式训练。
   • 执行模型的训练方法，传入训练轮数等参数。

7. 如果不是训练模式：

   • 进入测试模式，执行模型的自定义测试方法，传入测试图像目录。

8. 在 __name__ == '__main__' 中执行程序：

   • 执行命令行参数解析和主函数。

2.FaceAging.py

主要流程

1. 导入必要的库和模块：

   • 导入所需的Python库，如NumPy、TensorFlow等。
   • 导入自定义的操作（ops.py）。

2. 定义 FaceAging 类：

   • 在初始化方法中，设置了模型的各种参数，例如输入图像大小、网络层参数、训练参数等，并创建了 TensorFlow 图的输入节点。
   • 定义了图的结构，包括编码器、生成器、判别器等。
   • 定义了损失函数，包括生成器、判别器、总变差（TV）等。
   • 收集了需要用于TensorBoard可视化的摘要信息。

3. train 方法：

   • 从文件中加载训练数据集的文件名列表。
   • 定义了优化器和损失函数，然后进行模型的训练。
   • 在每个epoch中，随机选择一部分训练图像样本，计算并更新生成器和判别器的参数，输出训练进度等信息。
   • 保存模型的中间检查点，生成样本图像用于可视化，训练结束后保存最终模型。

4. encoder 方法：

   • 实现了编码器结构，将输入图像转化为对应的噪声或特征。

5. generator 方法：

   • 实现了生成器结构，将噪声特征、年龄标签和性别标签拼接，生成相应年龄段的人脸图像。

6. discriminator_z 和 discriminator_img 方法：

   • 实现了判别器结构，对输入的噪声特征或图像进行判别。

7. save_checkpoint 和 load_checkpoint 方法：

   • 用于保存和加载训练过程中的模型检查点。

8. sample 和 test 方法：

   • 生成一些样本图像以及将训练过程中的中间结果保存为图片。

9. custom_test 方法：

   • 运行模型进行自定义测试，加载模型并生成特定人脸的年龄化效果。
