If you want to however, compare the manually compiled versions with this installation, you would need to make conda forget about MKL (which installs openblas instead). This causes all MKL optimised packages to be re-installed (numpy, sklearn, etc). In addition, the blas header files are needed. [bash]conda install -c anaconda nomkl
  • EDIT 2: Numpy results with MKL and OpenBLAS on Ryzen and the two i7: Ran the same benchmark but in Python with Numpy. I tested both OpenBLAS 0.2.20 and MKL 2018.0.1 on my Ryzen machine with Numpy 1.13.3 as well as MKL 2018.0.1 with Numpy 1.13.1 on the i7 machines. Unsurprisingly the MKL performance on the Ryzen is much lower than OpenBLAS.

    The only prerequisite for NumPy is Python itself. If you don’t have Python yet and want the simplest way to get started, we recommend you use the Anaconda Distribution - it includes Python, NumPy, and other commonly used packages for scientific computing and data science.

    There are alternatives to OpenBLAS, but not many. Intel MKL is proprietary, so while it's a good option for (for example) the NumPy shipped by Anaconda, MKL is not an option for many redistributors (including NumPy itself, for its PyPI wheels and conda-forge packages).

    Jul 26, 2012 · There is a second, possibly surprising improvement, provided by set_openblas_num_threads(int). When I use “export OPENBLAS_NUM_THREADS=x”, implicit parallelization employs 4 threads, for all x >= 4, on my 4 dual-core system. However with set_openblas_num_threads, I can utilize all 8.

    The Python implementations of matrixstatistics and matrix_multiply use NumPy v1.14.0 and OpenBLAS v0.2.20 functions; the rest are pure Python implementations. Raw benchmark numbers in CSV format are available here and the benchmark source code for each language can be found in the perf. files listed here .

And no, it is not frequent to have numpy broken on Ubuntu if you knew how to install it. – edwinksl Jun 23 '16 at 19:11 I had a similar problem, simply because my LD_LIBRARY_PATH included a directory with an incompatible Openblas – xiawi Aug 25 '16 at 7:49
An MKL LAPACK linked scipy (also numpy) gives very good computing performance and is easily obtained using the anaconda package manager. In this choice, usual installation of LAPACKE is necessary for running dgesvd and zheev. When using anaconda, installing OpenBLAS is the easiest way to do. See OpenBLAS provided by conda (with multithread BLAS)

Other packages in Anaconda’s suite may depend on different versions of NumPy, but users may want access to the latest and greater version. (Anaconda’s term for this is “dependency pinning.”) R language users now have access to R version 3.4.2. All of R’s packages, including RStudio, were rebuilt using Anaconda’s new compilers.
