By the way, i have already verify the correctness of cuda installation before doing this. Thank you! ## Environment info (Required) ``` What to do: 1.Ubuntu 16.04 2.I'm using conda and use pip to install mxnet in the conda enviroment 3.cuda version 9.0 with cudnn 7 4.nvidia driver 384.130 ``` Package used (Python/R/Scala/Julia): mxnet-cu90 ## What have you tried to solve it? 1.try different verison of cuda driver and graphic card driver
