我正在使用Ubuntu 14.04 LTS运行AWS EC2 g2.2xlarge实例.我想在训练我的TensorFlow模型时观察GPU的利用率.我试图运行'nvidia-smi'时遇到错误.

ubuntu@ip-10-0-1-213:/etc/alternatives$ cd /usr/lib/nvidia-375/bin
ubuntu@ip-10-0-1-213:/usr/lib/nvidia-375/bin$ ls

ubuntu@ip-10-0-1-213:/usr/lib/nvidia-375/bin$ ./nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

我正在使用R插入包来生成模型.我在预处理过程中使用PCA来降低维数,然后尝试生成逻辑回归模型.

我刚刚将OS X从10.10.5升级到OS X El Capitan 10.11.

我试图将我的mac端口更新到版本2.3.3 ...

Mac端口出现此错误:

$ sudo port selfupdate
Error: Current platform "darwin 15" does not match expected platform "darwin 14

$ port -qv installed > myports.txt
Error: Current platform "darwin 15" does not match expected platform "darwin 14"
Error: If you upgraded your OS, please follow the migration instructions: https://trac.macports.org/wiki/Migration
Error: /opt/local/bin/port: Failed to initialize MacPorts, OS platform mismatch

有任何想法吗？

我尝试按照这些移植说明操作:

https://www.ghostwheel.com/merlin/Personal/notes/2015/09/14/installing-macports-on-os-x-10-11-el-capitan/

但是macport 2.3.3的'make'失败了:
