1. 背景
paddle.linalg.matrix_rank:用于计算输入矩阵的秩(Rank),基于NVIDIA cuSOLVER库提供的奇异值分解(SVD)实现。
例:paddle.linalg.matrix_rank(Tensor([3, 47721859, 5, 6],"float32"), None, False, )
shape
[3, 47721859, 5, 6]中[3,47721859]是batchSize。[5,6]是单个batch。代码核心逻辑
2. 现有问题:
[3, 47721859, 5, 6]耗时达10h+。3. 解决方案
4. 其他
Torch行为:显式报错。已添加到torch_error_skip.txt
