Hi @rjurney, thanks for posting and digging around on this! As far as upgrading to PyTorch 1.2: there are some breaking changes, and so we're planning to make the next version (likely v0.10.0) compatible with PyTorch 1.2. The staged PR (needs an update) is #1395.

Now for install issues: I wasn't able to repro any issue with pip install snorkel on Ubuntu or OSX. I tried out pip-tools for the first time (just using snorkel==0.9.1 in requirements.in), and here's what I got:

• On Ubuntu, the resolver gave torch==1.1.0 in requirements.txt and had no issue installing
• On OSX, the resolver gave torch==1.1.0.post2 in requirements.txt and had no issue installing
• On Ubuntu, pip install torch==1.1.0.post2 fails as you pointed to
• Running pip-compile -P snorkel==0.9.1 -P torch==1.1.0 on any platform gave torch==1.1.0 in requirements.txt and had no issue installing

Will one of those combos will work for you before we push the PyTorch 1.2 upgrade?

[rjurney]

Thanks for checking this out. Interesting. I’m using Anaconda Python on Ubuntu and OS X, and when I look at the list of artifacts and there is a 1.1.0.post2 so... I’m confused. I’ve had another issue like this with Anaconda pip recently. Is it possible for you to reproduce with Anaconda?

[henryre]

Hm ok you're activating a new Anaconda environment, installing pip-tools, then using that to install Snorkel? And is there any chance you generated a requirements.txt on OSX then tried installing with that on Ubuntu?

In the meantime, will using pip-compile -P snorkel==0.9.1 -P torch==1.1.0 work?

[rjurney]

@henryre Ok, yeah I think I did generate on Linux and then install in OS X. So that means I can only check in my requirements.in and not my requirements.txt and then I'll have to generate it each install. That makes sense.

jazzband/pip-tools#585 explains things well.

[rjurney]

@henryre So now I'm running into problems with libraries like fast-bert require torch>=1.2.0 and snorkel requires less than this. I understand this is not strictly speaking a Snorkel problem, but wanted to describe my use case :)

[henryre]

@rjurney got it. I expect more and more of these to pop up, and our next release will definitely be on PyTorch 1.2!

When will this release come out? It's there any timeline?
