未加载库：libmkl_intel_lp64.dylib，在OS X上使用Anaconda

Question

我无法在OSX（10.11.3）上使用支持MKL的NumPy版本。这些模块似乎安装正常，但是当我试图导入它时，我得到了错误Library not loaded: @loader_path/../../../../libmkl_intel_lp64.dylib。实际上，如果我搜索这个文件（mdfind -name libmkl_intel_lp64.dylib），则不会返回任何内容。这是软件包的问题还是我的安装问题？同样的过程在我的Windows机器上运行得非常完美。我可以毫无困难地安装nomkl构建并导入它，但是如果可以的话，我想使用MKL。在

编辑：从mkl包（http://anaconda.org/anaconda/mkl/files）手动安装dylibs似乎可以工作-也许这是一个bug？在

看起来由于某种原因，mkl包被安装，而归档文件没有被完全提取。后来的安装使用的是这种不完全抽取。运行conda install debug mkl时报告了此情况：

删除有问题的目录并重新安装mkl包修复了问题。在
