环境：
ubuntu16.04
cuda-9.0
pytorch 1.4
gcc6.5
安装spatial-correlation-sampler出现如下错误：

后查阅资料，找到相关问题说是由于gcc版本的问题。
在问题解答中指出：
nvcc 9.0 is not compatible with gcc>5.
cuda 9.2 supports gcc >=5
cuda 9.0 supports gcc<=5

所以我最终的解决办法是：

 CC=/usr/bin/gcc-5 CXX=/usr/bin/g++-5 CUDA_HOME=/usr/local/cuda-9.0/ pip install spatial-correlation-sampler

采用这个命令成功安装了spatial-correlation-sampler.

之后报出: 找不到 libcudart.so.9.0
按照之前的解决办法，在pycharm软件的run——>Edit configuration——>Environment variables添加环境变量：
LD_LIBRARY_PATH,设置值为/usr/local/cuda-9.0/lib64
或者在底部Terminal面板下运行：
sudo ldconfig /usr/local/cuda-9.0/lib64

问题即可解决！
