Because of this, conda will always install conda-forge's numpy, which is built against OpenBLAS and not MKL. If you use conda, you can install NumPy from the defaults or conda-forge channels: # Best practice, use an environment rather than install in the base env conda create -n my-env conda activate my-env # If you want to install from conda-forge conda config --env --add channels conda-forge # The actual install command conda install numpy to your account. accelerated linear algebra library - typically It is a small, bootstrap version of Anaconda that includes only conda, Python, the packages they depend on, and a small number of other useful packages, including pip, zlib and a few others. Adding default packages to … win-64 v1.19.2. See https://youtu.be/Ju6zw83PoKo for a more recent video on Python 3.6 with NumPy, SciPy, and Matplotlib. linux-32 v1.15.4. In the conda defaults channel, NumPy is built against Intel MKL. I don't actually care - I wouldn't mind having mkl, but I want a functioning environment and require some things from conda-forge, so I figured I'd start by installing everything from conda-forge to avoid any nasty binary incompatibility issues or the "mkl openblas dance". other libraries). About Gallery Documentation Support. You could try to install a specific NumPy version.

PyPI is the largest collection of packages by far, however, all separate package that will be installed in the users’ environment when they conda install nomkl numpy scipy scikit-learn numexpr still works for me on this problem. Spack is worth considering. When I attempt to install numpy into a fresh miniconda environment, however, I see mkl coming from defaults? be MKL (from the defaults channel), or even NumPy is the fundamental package needed for scientific computing with Python. If you’re in between “beginning” and “advanced”, Because the pinned specs are included with each conda install, subsequent conda update commands without --no-pin will revert NumPy back to the 1.7 series. On windows, do I need to worry at all about whether things come from defaults or conda-forge or are things mostly compatible now? Users don’t have to worry about number of alternative solutions for most tasks. @jjhelmus, I can replicate this by creating a new env conda create -n numpy-test numpy libblas=*=*mkl and then doing conda update --all.

To avoid this, you will need to make the defaults channel higher priority than conda-forge. When using pip, please ensure that binary wheels are used, and NumPy and SciPy are not recompiled from source, which can happen when using particular configurations of operating system and hardware (such as Linux on a Raspberry Pi). conda install. @ChiHangChen How did you force pyinstaller to use the OpenBlas variant of numpy in your pyinstaller exe file?
