Numpy 为什么'；blas是否在Anaconda3-2.4.1-Windows-x86_64中工作？

当我安装Anaconda3-2.4.1-Windows-x86_64时，结果是

True

，我发现numpy运行非常慢

当我安装Anaconda3-2.3.0-Windows-x86_64时，结果是

False

，numpy运行良好

在Anaconda3-2.4.1-Windows-x86_64中，

numpy.\uu配置\uuu.show（）

输出：

import numpy

id(numpy.dot) == id(numpy.core.multiarray.dot)

在Anaconda3-2.3.0-Windows-x86_64中，

numpy.\uu配置\uuu.show（）

输出：

    library_dirs = ['C:\\aroot\\stage\\libs']
    define_macros = [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]
    include_dirs = ['C:\\aroot\\stage\\include']

如何修复它？

哪个版本的numpy？你安装了MKL吗？Anaconda3-2.4.1-Windows-x86_64中的numpy版本是1.10.1，Anaconda3-2.3.0-Windows-x86_64中的版本是1.9.2。如何判断是否安装了MKL？@Paul Hlooks好像没有。这可能只是numpy的倒退。创建两个不同的环境，每个版本的numpy都可以使用，如果您发现类似的差异，请报告。您可以使用

conda install MKL安装MKL
