我想使用 Dlib 进行面部标志检测,并尝试将其安装在我的 macOS Sierra 上。我按照 main GitHub Repo for dlib 中的说明进行操作.
进入示例文件夹后,我首先执行了以下命令,没有出现错误:
mkdir build; cd build; cmake .. ; cmake --build .
回到父目录,我执行了以下命令:
sudo python2.7 setup.py install
完成 38% 后遇到 20 多个错误:

[ 35%] Building CXX object dlib_build/CMakeFiles/dlib.dir/stack_trace.cpp.o

稍微研究一下,我觉得有一条小路径(到 python)我需要更改才能让一切正常工作。引用a similar problem ,他更改了 CMakeCache.txt 中的一些路径,但我不确定是哪一行/哪一部分。此外,还有 4 个 CMakeCache.txt 文件。我应该更改哪一个(如果有的话)?
Ajays-MacBook-Pro:dlib Ajay$ find . -name "CMakeCache.txt"
./examples/build/CMakeCache.txt
./examples/build/cpp11_test_build/CMakeCache.txt
./tools/python/build/CMakeCache.txt
./tools/python/build/cpp11_test_build/CMakeCache.txt
还有其他解决办法吗?我应该怎么办?任何帮助将不胜感激!
最佳答案
看我的回答here
长话短说,你可以得到这个问题even with xQuartz installed .
Git 中的最新版本似乎可以工作,但 PyPi 存储库尚未更新。
在那之前,使用这些命令:
git clone https://github.com/davisking/dlib.git
cd dlib
pip install .
关于python - macOS - 安装 dlib 时遇到问题,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/41289426/
