Well, I personally would have a look at the 1.0 preview, as there are some awesome new features.
Especially if you are learning PyTorch and don’t write some production code etc., I would play around with the nightly build. It’s also really easy to install, so that you don’t even have to build from source.
That’s just my biased opinion, and I have to admit I use a lot of conda environments for the stable release, nightly build, and several builds from source.
