Re: [Kwant] Installation instructions for Kwant on WSL

Bas, Using conda is a good solution, but a caveat is that Ubuntu anaconda on WSL is broken. There are 2 problems with it: - broken MKL : numpy simply crashes. Some bugs are avoided by setting KMP_AFFINITY=1 as the environment variable, but it’s not stable. - ABI incompatibility of libraries. Basically when I tried to compile kwant and link it to conda libraries, I get all kinds of errors. These problems might be possible to circumvent, but conda is a binary distribution, so I gave up and choose to compile from scratch. Christoph : I’ll give it a try. Andrey.

Sorry, I wasn’t clear in my last message, I accidentally copied the instructions for installing conda and kwant on OSX.

What I meant to say is, that you can just install conda http://conda.pydata.org/docs/download.html for Linux and use it on WSL (at least from Googling a bit I see that other packages work).

As far as I understand, you could just use conda:

Conda Conda is a cross-platform package and environment manager that installs, runs, and updates packages and their dependencies. It allows you to easily set up and switch between environments on your local computer. Conda is included in all versions of Anaconda and Miniconda. Anaconda is Python distribution that includes 150 installed of the most popular Python packages for science. Miniconda is an lighter alternative to Anaconda and comes just with Python and conda. Open a terminal and download Miniconda http://conda.pydata.org/miniconda.html (or Anaconda https://www.continuum.io/downloads#osx) by running wget https://repo.continuum.io/miniconda/Miniconda3-latest-MacOSX-x86_64.sh Install Miniconda with bash Miniconda3-latest-MacOSX-x86_64.sh and follow its instructions. Make sure that conda is in your PATH, which you can do by adding export PATH="$HOME/miniconda3/bin:$PATH" to your .bashrc or .bash_profile. Add the conda-forge https://conda-forge.github.io/ channel and install Kwant and its dependencies with conda config --add channels conda-forge conda install kwant

Hi Andrey,

Thanks for sharing your instructions. Do you see a way to automatize this somehow, e.g. to provide Kwant packages for WSL? Is it possible to install our regular Ubuntu Kwant packages [1] in WSL?
