Error running with provided LDPC code #2

Open mlscsdn opened 2 years ago

mlscsdn commented 2 years ago

使用提供的LDPC码运行出错，大概是某个tensorflow向量维度不一致的错误。而当我使用BCH码或汉明码时成功运行。 There is an error when running with the provided LDPC code, probably because of an inconsistent tensorflow vector dimension. And when I use BCH code or Hamming code it runs successfully. `Traceback (most recent call last):

请问你使用的tensorflow和python是什么版本的呢

请问你使用的tensorflow和python是什么版本的呢

tensorflow 2.1 + python 3.7. 这个代码并不灵活，换另一个LDPC码后就出错了。错误大概是在BP算法中计算节点之间传递的信息时出错。

好的好的，我研究下他怎么计算的

请问方便分享一下您基于TF2.1的代码？我现在被困得很痛苦，用TF1.x
