  • 不用提在GPU还是CPU运行了,这个任务太简单了。

  • training cost 那个图看起来太像心电图了,看看怎么样改一下能看出来cost是在降吧。(把test cost也画到图里)

  • 以前版本的这张图: https://githubraw.cdn.bcebos.com/PaddlePaddle/book/develop/01.fit_a_line/image/predictions.png?raw=true
    还是比较容易让人看懂效果的。 可以考虑用matplotlib也打印出来类似的图,展示效果。

  • 可以考虑对比一下mse loss 和 paddle的smooth_l1_loss (把结果都画到上面说的图上的话,能看出来区别)。
