The build fails even though I use the same dockerfile from the repo, all I add is openmpi. (but it fails without it too).
In the new Dockerfile from main pytorch repo it is working with only 1 line change.
I don’t fully understand where it fails and what causing the failure in pytorch/builder.
I made it work ~4 months ago for the nightly version, but I can’t make it work again for pytorch 1.4 (or later).
