From this 19 thread:



PyTorch no longer supports this GPU because it is too old.


From 0.3.1 onward, cuda capability 5.0 will not be included in the pre-packaged binary release (so all torch.cuda related stuff will not work).
You will be able to get pytorch to work with such architecture by compiling from source (so all operations will work).


Compiling from source is pretty straight-forward. You can find the instructions here 389. Let me know, if you have any trouble with it.
