【中文标题】为啥我在编译 dlib python 接口时得到“dlib is not going to use CUDA”【英文标题】：Why I get "dlib isn't going to use CUDA" when I compile dlib python interface为什么我在编译 dlib python 接口时得到“dlib is not going to use CUDA” 【发布时间】：2018-09-25 05:44:18 【问题描述】：

我在启用了 CUDA 9.1 的 Ubuntu 16.04 上使用 cmake 3.11.0 编译了 dlib 19.10。它进展顺利，没有遇到任何问题！

这里是运行cmake ..的输出

但是当我运行 sudo python3.5 setup.py install 时，我收到一条消息说 CUDA 已找到，但它不会被使用：

-- *** CUDA was found but your compiler failed to compile a simple CUDA program so dlib isn't going to use CUDA.

虽然它在发现 CUDA 和 CuDNN 之前向我展示了：

-- Found CUDA: /usr/local (found suitable version "9.1", minimum required is "7.5") 
-- Looking for cuDNN install...
-- Found cuDNN: /usr/lib/x86_64-linux-gnu/libcudnn.so

这是我运行sudo python3.5 setup.py install时的全部输出：

如果我使用选项 --yes USE_AVX_INSTRUCTIONS 运行 setup.py，我不会收到任何有关使用 CUDA 的消息。我是这样运行的：

sudo python3.5 setup.py install --yes USE_AVX_INSTRUCTIONS

我不知道当我使用该标志时它会导致什么，我不确定它是否禁用使用 CUDA 编译它！

有没有人知道为什么它在构建 Dlib 时成功找到 CUDA 而在我想编译 Dlib 的 Python 接口时却失败了？

我尝试按照Installation guide by dlib.net 的建议使用 Cmake 编译 Dlib 的 Python 接口，但它也失败了！

EDIT1

我跑sudo python3.5 setup.py install --clean

现在在抱怨

-- Could NOT find CUDA (missing: CUDA_INCLUDE_DIRS CUDA_CUDART_LIBRARY) (found suitable version "9.1", minimum required is "7.5")

虽然 CUDA_INCLUDE_DIRS 和 CUDA_CUDART_LIBRARY 在我的环境中定义

echo $CUDA_CUDART_LIBRARY && echo $CUDA_INCLUDE_DIRS
/usr/local/cuda-9.1/lib64/libcudart.so
/usr/local/cuda-9.1/include

编辑2： 在没有 sudo 结果的情况下运行 python3.5 setup.py install --clean

running install
Checking .pth file support in /usr/local/lib/python3.5/dist-packages/
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/usr/local/lib/python3.5/dist-packages/test-easy-install-7244.pth'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /usr/local/lib/python3.5/dist-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

  https://pythonhosted.org/setuptools/easy_install.html

Please make the appropriate changes for your system and try again.

EDIT3： 我已经通过以下操作完成了使用 cmake 编译 dlib：

mkdir build
cd build
cmake ..
cmake --build . --config Release
sudo make install
sudo ldconfig

【问题讨论】：

给——干净。您可能在构建文件夹中有一些破坏的东西。我做到了，检查更新！它现在抱怨在设置时找不到 CUDA_INCLUDE_DIRS 和 CUDA_CUDART_LIBRARY！我可以将这两个硬编码的变量传递给 setup.py 吗？在没有 sudo 的情况下运行这一切我的权限被拒绝了！我可以将硬编码的 CUDA_INCLUDE_DIRS 和 CUDA_CUDART_LIBRARY 变量传递给 setup.py 吗？ 【参考方案1】：

使用 CUDA for Python 3.x 构建 DLIB Python 模块。

sudo python3 setup.py install --yes USE_AVX_INSTRUCTIONS --yes DLIB_USE_CUDA

注意：在构建 Python 模块之前不需要构建 CUDA。

【讨论】：

根据 Davis King 的说法，正如这里提到的 peshmerge.io/… 你只需要运行 python setup.py install 假设 python 是 python3 的别名！

以上是关于为啥我在编译 dlib python 接口时得到“dlib is not going to use CUDA”的主要内容，如果未能解决你的问题，请参考以下文章

为啥我在安装 dlib 时收到此错误“检查日志以获取完整的命令输出”？

在 Ubuntu 上为 Android 编译 dlib

使用 Dlib 进行地标检测期间的 Boost.Python.ArgumentError

为啥我无法在 Anaconda 或 python 中正确安装 dlib

使用 python3.5 安装 dlib 时遇到麻烦

为啥接口的显式实现不能公开？
