No.82:为神经网络编译器 CINN 增加 triangular_solve 算子

在 cublas 里面,矩阵使用列优先,而 CINN 用的行优先,所以要对计算的公式的两边做转置。

$$AX = B$$

变成了

$$X^T A^T = B^T$$

输入的参数:

  • left_side: 反过来取值,经过转置,参数矩阵从左边变到了右边
  • upper: 参数矩阵原本取上半部分,转置之后要去下半部分
  • transpose_a: 保持不变,因为和上述逻辑不冲突。
  • unit_diagonal: 这个参数更加不相干了。

@thisjiang 您好~可以帮忙看看这个算子吗?单测 Paddle-CINN-CI 没有通过,检测 docker md5 失败了, 应该如何解决?

这个CI不用管,目前还在开发阶段,只用Required的CI通过了就行
