May be you can use anaconda, it creates a virtual environment. Also it has huge number of repos. you can install just by doing "conda install cython" after installing the anaconda.

well, I encounter the same problem and I have used anaconda

[baristahell]

I encounter the same issue, has someone found how to deal with it?
I commented out the GPU-related lines and now i get this. (I'm using caffe and the original repo but it's the same thing)

[LinkToPast1990]

I using ubuntu16.04，anaconda python2.7 and I face the same problem……how to fix this？

[maqy1995]

I encounter the same issue,and the reason is the path to Faster-RCNN_TF include chinese.
After I move the file to /home/username/,the issue not appear anymore.
By the way,i use the tensorflow-gpu 1.4.1 ,and I encounter the an issue about nsync_cv.h ,the web fixes my problem. #245
