caffe powered和GPU启用Microsoft Azure VM

Question

我正在尝试为Azure中的模型培训构建VM。我发现这个Data Science Virtual Machine for Linux (Ubuntu) VM似乎是一个合适的候选者。

不幸的是，当我启动VM并安装了caffe先决条件时，我无法运行测试。我在make runtest上收到了以下错误（make all和make test已完成且没有错误）：

是否可以使用caffe在Azure中启动适合启用GPU的机器学习的虚拟机？

有关VM here的所有详细信息

Answer 1

Ubuntu的数据科学虚拟机（DSVM）已经在/ opt / caffe中安装了Caffe。要在GPU上使用它，请通过选择其中一个NC大小来创建具有K80 GPU的VM。 （请务必选择HDD作为存储类型，否则NC尺寸将不会出现。）Caffe将随时可用。

另请注意，PyCaffe可用。在终点站：

source activate root

然后python将提供PyCaffe。
