PaddlePaddle如何用GAN生成MINIST手写数字图？
摘要：GAN 性能的提升从生成器 G 和判别器 D 进行左右互搏、交替完善的过程得到的。所以其 G 网络和 D 网络的能力应该设计得相近，复杂度也差不多。这个项目中的生成器，采用了两个全链接层接两组上采样和转置卷积层，将输入的噪声 Z 逐渐转化为

/opt/conda/envs/python35-paddle120-env/lib/python3.7/site-packages/paddle/fluid/layers/utils.py:26: DeprecationWarning: `np.int` is a deprecated alias for the builtin `int`. To silence this warning, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
