环境：Win10，python35,CUDA90,tensorflow
github：https://github.com/matterport/Mask_RCNN
这个版本下的训练是在keras下，运行比较慢，因此想找一个能快速训练的版本，如下链接。
github地址：https://github.com/CharlesShang/FastMaskRCNN
但是在编译gpu_nms.cu时一直报错，各种错！！！
然后鼓捣两天，从issue上找：https://github.com/endernewton/tf-faster-rcnn/issues/335（mask rcnn在faster-rcnn的基础上改进）
我一开始按照他的步骤改int_t为int64_t,发现还是不行，然后直接安装原文件，在setup.py同一目录下新建setup_cuda.py专门编译.cu，setup_cuda.py文件如下：

然后在该路径下命令行运行python setup_cuda.py build_ext --inplace，突然就可以了，上图，好吧！
