Bug反馈

[weixians]

作者您好，非常有幸能阅读到您这篇论文，让我受益匪浅。 关于论文的代码实现，这里我发现了几个问题。

1. 由于将邻接矩阵转成了sparse，导致内存爆炸，目前还没有人能够使用这份代码进行训练；
2. 代码中有比较明显的低级错误，麻烦您改一下。

您好，显存原因可以调小规模训练，关于该问题确实不规范但我测试了一下不影响结果

for me the same

[Lei-Kun]

你可以降低pytorch版本试试，我用的1.4.0，或者按照报错提升修改下，应该没问题

[MagMueller]

The error occurs, because the code uses the same critic for Job and Machine Policy. Therefore the same v value is used in the loss function and after the job policy finished its backward step, the machine policy says, that the gradients are changed.

[Lei-Kun]

I've revised the 'PPOwithValue.py', please check for detials.
