Indexing Failure BUG about torch HOT 4 CLOSED

Hi, thx! @mdushkoff is this only observed on intel/torch or it also exists on original torch?
We did rewrite torch.rand() for better performance, however the guy who wrote this @MlWoo is in hospital now. Will get back to this issue when he finished his therapy.

from torch.

@mingfeima I'm so sorry to hear @MlWoo is in the hospital, I hope that they have a swift recovery!

Yes this is only observed in the intel/torch build, and not the original torch build as far as I can tell. I don't think it has much to do with the torch.rand() function as it has been corrupting data that has been loaded in with torch.load(...) and other structured data.

@mdushkoff I have looked into the code and identified the problem. After removing the bug, the result seems OK, here is my test:

th> x = torch.rand(2000,20000)+3
                                                                      [0.4202s]
th> ind = torch.randperm(x:size(2))[{{1,10}}]:long()
                                                                      [0.0012s]
th> sx = x:index(2,ind)
                                                                      [0.0461s]
th> print("Slice Range: " .. sx:min() .. "," .. sx:max())
Slice Range: 3.000022164546,3.9997919152956
                                                                      [0.0001s]
