安装mxnet仍是遇到很多麻烦事,如今简单记一下,挖个坑,后续详细补充,打算写一下个人mxnet探索之旅。html
更新: 具体安装mxnet,cuda,opencv过程已经补坑——点击进入git
不知道为何,在cuda7.5+ubuntu14.04amd64 + opencv2.4.13时,会显卡驱动有问题,没法显示桌面.可是能够正常使用。后续我改成16.04+cuda8.0rc+opencv2.4.13,解决了桌面显示问题且正常使用,可是在想把opencv2.4.13换为opencv3.10时,编译opencv3.10时会报错,关于cudalegacy模块,以下; github

经屡次尝试,都不成功。暂时放弃使用,初步猜想是由于,opencv3.10是2015年年底发行的,cuda8.0rc是2016.05发行的,因此自己opencv3.10不支持cuda8.0rc,可是我尚未去github问(opencv2.4.13是2016.05发行,使用正常),后续还会再尝试,到时再更新。ubuntu
我我的是由于硬件问题,因此环境选ubuntu16.04+cuda8.0rc。若是没这个限制最好选择比最新版本低一个版本,以求稳定。ide
不得不说,搭建环境很耗时间,环境稳定后,不要轻易改变。ui
