我正在尝试在安装了Cuda的Ubuntu 14.04 EC2实例上安装cudamat。
安装脚本失败，“无法执行'nvcc'：没有这样的文件或目录”。我添加了一行来回显环境变量$ PATH，它没有先前导出的shell变量：
(deeplearning) ubuntu@ip-x-x-x-x:~/cudamat$ sudo python setup.py install
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin running

--compiler-options=-fPIC unable to execute 'nvcc': No such file or directory error: command 'nvcc' failed with exit status 1
如果有人好奇，这是来自.bashrc的导出命令：
export PATH=/usr/local/cuda-7.5/bin:/home/ubuntu/.virtualenvs/deeplearning/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
export LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib64:
我确认我的路径设置了：
(deeplearning) ubuntu@ip-x-x-x-x:~/cudamat$ env
LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib64
PATH=/home/ubuntu/.virtualenvs/deeplearning/bin:/usr/local/cuda-7.5/bin:/home/ubuntu/.virtualenvs/deeplearning/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
