@apaszke I built from the most recent source as follows.
export CMAKE_PREFIX_PATH=/home/kimjook/anaconda3
conda install numpy mkl setuptools cmake gcc cffi
conda install -c soumith magma-cuda75
git clone https://github.com/pytorch/pytorch
cd pytorch
pip install -r requirements.txt
python setup.py install

Could you let me know which closed issues you are referring to? https://github.com/pytorch/pytorch/issues/665 5 seems somewhat related but there is no build error in my case.
Thanks! (I understand that supporting old devices is annoying, but I am somewhat frustrated since my almost the same model worked well on Torch7 doesn’t work on PyTorch.)
