在Ubuntu 14.04上设置caffe，但在运行时遇到错误classify.py

我在安装了CUDA的Ubuntu 14.04虚拟服务器上安装Caffe（无驱动程序），使用https://github.com/BVLC/caffe/wiki/Ubuntu-14.04-VirtualBox-VM作为灵感。我已经安装了所有必需的依赖关系，并且一步一步地遵循了所有说明，但在尝试测试安装时遇到以下错误。在Ubuntu 14.04上设置caffe，但在运行时遇到错误classify.py

在关于步骤： “修改蟒蛇/ classify.py添加--print_results选项”我曾在classify.py通过修改代码是相同的官方朱古力分布

。不知道这是否是导致问题的步骤，但我认为我会添加额外的信息以防万一。

我得到的错误是如下：

那么，locale名称通常是一种语言（和可选编码），而不仅仅是编码。你在'LANG'环境变量中有什么？ – user3159253

查看当前shell环境，这些变量：LC_ALL，LC_CTYPE，LANG，LANGUAGE：

set | grep -a '^LC_ALL=.'; set | grep -a '^LC_CTYPE=.'; 
set | grep -a '^LANG=.'; set | grep -a '^LANGUAGE=.'

可能是第一个印刷线将包含这些变量等于 'UTF-8' 之一。这是错误的。

适当的语言环境应该有语言和可选的国家和编码规范，如'en'或'en_US'或'ru_RU.UTF-8'。有一个特殊的区域设置'C'作为后备。

所以，你可能会永久地重新定义你的语言环境中/etc/default/locale（不要忘记重新加载您的设置，最简单的办法就是注销/登录），或简单地覆盖它特定命令：

> LC_ALL=C python python/classify.py --print_results examples/images/cat.jpg foo

嗨user3159253非常感谢花时间看我的问题。所以我采纳了您的建议，并在我重新定义我的区域设置之前，再次运行命令，更改特定命令的shell环境。我仍然遇到libdc1394错误：虽然我没有收到有关未知语言环境的错误，但未能初始化libdc1394错误。 – tsailun

那么，你需要更新你的问题:)这将是一个http://stackoverflow.com/questions/12689304/ctypes-error-libdc1394-error-failed-to-initialize-libdc1394 :)的副本 – user3159253
