安装具有GPU支持的dlib时发生错误

Posted 2021-04-12

我已经安装了Cmake，visual studio 2019和anaconda。我正在尝试在gpu支持中使用Dlib。但是每次我尝试安装它时，运行python setup.py都会出现以下错误。我想将Dlib与GPU（CUDA）支持一起使用。

有没有解决此问题的方法。首先，我想知道是什么导致了此问题。

答案

--set的参数setup.py应该采用格式

--set <variable>=<value>

这将cmake参数转换为-D<variable>=<value>，完全适合cmake synopsis。

例如代替

--set USE_AVX_INSTRUCTIONS

使用

--set USE_AVX_INSTRUCTIONS=ON

---

--no的参数setup.py没有分配（=<value>）部分，因为

--no <variable>

将自动转换为cmake参数-D<variable>=no。
