also setup a fresh amazon instance, only installed python, pip, ipython and ran:
pip install http://download.pytorch.org/whl/cu75/torch-0.2.0.post3-cp27-cp27mu-manylinux1_x86_64.whl 

(Python 2.7, no CUDA, pip-installed 0.2.0_3 (didn’t install torchvision))
The dummy example I pasted above also gives segfault on the fresh machine.
