在虚拟机centOS 7上安装dlib,安装结束显示Successfully了,但是进入python后import dlib却提示“undefined symbol:cblas_ddot”。 网上搜了很久基本没什么对应的解决方案,dlib的github中有一个issue是类似的问题:https://github.com/davisking/dlib/issues/154,但是跟我的请情况也不太一样。 使用yum安装blas和lapack也...

We are using MKL in NumPy. We noticed that performance of cblas_ddot (running on single thread) **significantly** depends on values of incx and incy.
Here, I have found that cblas_dnrm2 is significantly slower (3.4 s) than the corresponding cblas_ddot call (0.5 s) using one thread. This is very surprising for me, because if I use cblas_ddot to calculate the 2-Norm it is faster (0.3 s) than cblas_dnrm2. ...
