我一直在使用this在我的 Windows 10 系统上安装 caffe 的资源。
我首先通过命令提示符为 Python 安装必要的依赖项:
C:\Users\MYNAME>conda config --add channels conda-forge
C:\Users\MYNAME>conda config --add channels willyd
C:\Users\MYNAME>conda install --yes cmake ninja numpy scipy protobuf==3.1.0 six scikit-image pyyaml pydotplus graphviz
然后我在我的 C:\ 目录中创建了一个名为 caffe 的空目录。然后我通过命令提示符进入该目录并键入以下命令:
C:\caffe\caffe>git clone https://github.com/BVLC/caffe.git
C:\caffe\caffe>cd caffe
然后我打开 /scripts 目录中的文件 build_win.cmd 并编辑了一些内容。编辑后的文件如下所示:

当 build_win.cmd 明确包含以下行时，我的系统中如何检测不到这些文件:
set PATH=C:\Users\MYNAME\Anaconda3;C:\Users\ MYNAME\Anaconda3\Scripts;C:\Users\MYNAME\Anaconda3\Library\bin;!PATH!
相关的 python 文件也存在于我的系统中。
.cmd 文件找不到的 PythonLibs 存在于 Anaconda3 目录中。
Numpy 也存在于该目录的一个子目录中。
我什至可以直接从命令行运行 python:
此时，我不知道为什么我会收到有关 numpy 和 Python 库的错误。如果您有任何建议，请告诉我。
编辑:
看完this video后，我在我的项目目录中运行了以下命令:
C:\caffe\caffe>python scripts\download_prebuilt_dependencies.py --msvc_version=v140
输出如下:
ERROR: Could not find url for MSVC version = v140 and Python version = 3.6.
Available combinations are: [('v120', '2.7'), ('v140', '2.7'), ('v140', '3.5')]
这是否意味着我必须切换到 Python 3.5 才能使用这个框架？
编辑:
我下载了python 3.5.5，执行了和上面一样的步骤，得到了同样的错误。
我更多地考虑了CristiFati的建议并执行了以下命令:
C:\caffe\caffe\build>cmake -DPYTHON_EXECUTABLE=C:\Users\Abdullah Siddiqui\Anaconda3\python.exe ..
这给了我以下输出:

我现在明白问题是由Python 2.7 的可执行文件用于编译引起的。 如何让构建脚本指向 python 3.5？
编辑:
我正确地运行了 cmake 命令，如下所示，但我现在看到了新的错误。
C:\Users\MYNAME\projects\caffe\build>cmake -DPYTHON_EXECUTABLE="C:\Users\MYNAME\Anaconda3\python.exe" ..
它给我这些错误:
-- Could NOT find Glog (missing: GLOG_LIBRARY)
CMake Error at cmake/ProtoBuf.cmake:6 (find_package):
Could not find a configuration file for package "Protobuf" that is
compatible with requested version "".
最佳答案
cmake 有“标准”方式定位外部包安装(通过脚本)。这适用于 Python。当找到这样的包时，会设置一些变量，通常:
${PACKAGE}_FOUND=ON(包状态标志)${PACKAGE}_INCLUDE_DIRS(包括目录 - 在编译时使用)${PACKAGE}_LIBRARIES(库 - 在链接时使用)
当搜索 numpy ( [GitHub]: BVLC/caffe - (windows) caffe/cmake/Modules/FindNumPy.cmake ) 时，搜索 PythonInterp(标准 cmake 模块)(并使用)。如初始输出所示:
检测到-- Found PythonInterp: C:/cygwin64/bin/python2.7.exe (found suitable version "2.7.14", minimum required is "2.7")
python 2.7(没有安装 numpy 模块)，导致 numpy发现失败。
查看 FindPythonInterp.cmake 脚本，我注意到它设置了(除其他外)${PYTHON_EXECUTABLE} (cmake) 变量。
将该变量“手动”设置为 cmake(通过传递 cmdline 参数)，将是下一个合乎逻辑的事情(因为我不知道这是否单独是够了，我只是添加了一条评论):
-DPYTHON_EXECUTABLE="c:\path\to\python3"
注意:不要混合使用 Cygwin 和 native Win 工具，因为您可能会遇到微妙的问题。
关于python - 当我尝试在 Windows 10 上安装 caffe 时，脚本找不到 python 库和 numpy，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52358784/
