Conditional GAN是由 Ian Goodfe等人提出的一个GAN的改进模型，在GAN的基础上加入用户指定的标签，生成器根据标签，生成与标签相关的样本；判别器根据标签判断图片（在图片真实的基础上加入与标签相关的要求，只有二者同时满足才标记为1，其余情况标记为0）。从而达到根据指定标签生成图片的功能，论文链接如下：

简介：
A Jittor implementation of Conditional GAN (CGAN).
本题目为第三届计图人工智能挑战赛计图挑战热身赛，南开大学计算机图形学小作业。
技术介绍

第三届计图人工智能挑战赛 (educoder.net)
在数字图片数据集 MNIST 上训练 Conditional GAN（Conditional generative adversarial nets）模型，通过输入一个随机向量 z 和额外的辅助信息 y (如类别标签)，生成特定数字的图像。
其中使用到了计图（Jittor），安装与使用链接如下：

环境要求
主要为Jittor框架的环境要求：（来自赛题官网）
Jittor框架对环境要求如下:
如果您不希望手动配置环境，我们推荐使用 Docker 进行安装。 除此之外，您还可以使用 pip 安装和手动安装。
注意：目前Jittor通过WSL的方式在Windows操作系统上运行，WSL的安装方法请参考微软官网，WSL版本目前尚不支持CUDA。
结果展示
本代码在给定的框架基础上进行修改，生成图像见reault.png
