要在AWS EC2 g2.2xlarge实例上的Ubuntu 14.04.1 LTS上安装CUDA 6.5,无论是通过.deb文件还是.run文件安装

.sudo ./cuda_6.5.14_linux_64.run --kernel-source-path=/usr/src/linux-headers-3.13.0-34-generic

我总是得到关于丢失drm.ko的相同错误.代码编译似乎很成功.下面是日志.(我在安装前重新启动)

内核模块编译完成.

无法确定是否启用了安全启动:没有此类文件或目录

内核模块加载错误:没有这样的文件或目录

我正在使用Ubuntu 14.04上的Python 3.4进行开发.我试图做递归Pool.map().在我调用之后g(),它会挂起并且永远不会返回.

import multiprocessing as mp

pool = mp.Pool()

def d(x):
    return x / 2.0


def f(x):
    w = pool.map(d, x)
    return w

def g():
    v = pool.map(f, [[1, 2], [3, 4]])

    print(v)
