Hello,
I’m trying to compile the master branch (pytorch >= 0.4, commit 4251e38) on a raspberry pi 3.
In the past, it worked (v0.4a after the pull request  #4473) but now i have got a memory issue when it compiles aten_dispatch.cpp : virtual memory exhausted: Cannot allocate memory
I tried augmenting the swap space (up to 3 Go) but it still fails…
Do you have any suggestion to make it compile ?
