undefined symbol: state
When I ran "bash make_cuda.sh", it didn't raise any mistake, but when I ran "python test/test.py", it reported "correlation_package/_ext/corr/_corr.so: undefined symbol: state", I don't know how to solve it. I use Ubuntu16.04, cuda8.0 and pytorch 0.2
Can you try the installation script using Anaconda to set up the environment (copied from readme under PyTorch)?
setup environment
conda create -n pwcnet_test python=2.7 anaconda conda activate pwcnet_test
install pytorch and other dependencies
pip install http://download.pytorch.org/whl/cu80/torch-0.2.0.post3-cp27-cp27mu-manylinux1_x86_64.whl pip install torchvision visdom dominate opencv-python cffi
install external packages
cd external_packages/correlation-pytorch-master/ bash make_cuda.sh cd ../../
When I run "conda activate pwcnet_test", the error is "CommandNotFoundError: 'activate is not a conda command.", so I replace it by "source activate pwcnet_test". Then I just do as the installation script tells, and when I run "python script_pwc.py './data/frame_0010.png' './data/frame_0011.png' './tmp/frame_0010.flo'", it still reports that "ImportError: /home/zhang/anaconda2/envs/pwcnet_test/lib/python2.7/site-packages/correlation_package-0.1-py2.7-linux-x86_64.egg-tmp/correlation_package/_ext/corr/_corr.so: undefined symbol: state".
Can you try again by installing anaconda3 and follow the instructions of the readme in this repository?

Installing the post3 version instead of post2, i.e. http://download.pytorch.org/whl/cu80/torch-0.2.0.post3-cp27-cp27mu-manylinux1_x86_64.whl solved the problem for me.
