conda 3.6 installation currently broken due to 3.6.1 ABI breakage #1383
Description
I'm posting here so others with this problem find it. But as I mentioned on Twitter, I don't think this is your bug to fix. Likely 3.6.2 must be pushed out or 3.6.1 marked invalid in conda.
Following these minimal install instructions:
conda create -p pyvenv python=3.6
conda activate ./pyvenv
conda install pytorch torchvision -c soumith
Conda downgrades 3.6.1 to 3.6.0 but it still fails. Then just trying to import torchvision gives this callstack:
Python 3.6.0 |Continuum Analytics, Inc.| (default, Dec 23 2016, 12:22:00)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import torchvision

>>> quit()
UPDATE: maybe the problem is occurring now because they did mark 3.6.1 as incompatible in conda and you're building against it?
