I am using Win 10. I tried installing ChainerCV through pip. I want to know what can be done to solve this problem. Also what is behind this issue: not having VisualStudio, dependency issues or any other thing. Is having CUDA necessary to run ChainerCV?

P.S I have chainer and other dependencies running properly.

    I'm not sure the root cause but it seems it fails around cython stuff. https://github.com/chainer/chainercv/blob/master/chainercv/utils/bbox/_nms_gpu_post.pyx Did you install cython? if not please try setup cython install and try installing chainercv again. Also, if you can try in Linux environment, it is more easy way to avoid this issue. – corochann Dec 28 '18 at 12:15
  • We need to install Visual Build Tools 2015 version. That has solved the error that I have been getting. – TulakHord Jan 30 '19 at 09:20
