Recently there was this thread (https://twitter.com/gneubig/status/899826900834689028 31) on Twitter about how PyTorch is currently much slower than DyNet (between 10x and 20x). Is this exclusively a problem with CPU runs, i.e., the code would be much more competitive on the GPU? Why is it so slow and how likely is to be addressed in the recent future? Soumith promised (https://twitter.com/haldaume3/status/900775899431305217 22) that it would be addressed soon, but I would like to be sure that it is in fact addressable before investing too much into PyTorch (which I’ve already done a bit). A 20x slowdown is prohibitively slow.
