res = torch.linalg.lstsq (a_matrix, b_matrix).solution. So that we stop using a deprecated function. One caveat is that maybe some tests might start failing (due to its inherent flakiness), and we should fix the tests that break on the way. It would be good to fix this before the next release, so that users don't get those warnings. cc @vfdev-5.

I noticed that the results of torch.linalg.lstsq are not reproducible, which is not the case for torch.lstsq. By not reproducible I mean that running the same operation twice will yield to a different result. This causes me problem since my experiments become irreproducible, which is not the case with the previous implementation.

torch.linalg.lstsq() has reversed arguments and does not return the QR decomposition in the returned tuple, (it returns other information about the problem). The returned solution in torch.lstsq() stores the residuals of the solution in the last m - n columns in the case m > n.

Warning. torch.lstsq() is deprecated in favor of torch.linalg.lstsq() and will be removed in a future PyTorch release. torch.linalg.lstsq() has reversed arguments and does not return the QR decomposition in the returned tuple, (it returns other information about the problem). The returned solution in torch.lstsq() stores the residuals of the solution in the last m - n columns in the case …
